Here is a checklist of steps you need to follow to submit a single file or user package for our consideration. Following these steps will save both you and us time. See existing files in packages in the source directory for examples. If you are uncertain, please ask on the lammps-users mailing list.
* All source files you provide must compile with the most current version of LAMMPS with multiple configurations. In particular you need to test compiling LAMMPS from scratch with `-DLAMMPS_BIGBIG` set in addition to the default `-DLAMMPS_SMALLBIG` setting. Your code will need to work correctly in serial and in parallel using MPI.
* For consistency with the rest of LAMMPS and especially, if you want your contribution(s) to be added to main LAMMPS code or one of its standard packages, it needs to be written in a style compatible with other LAMMPS source files. This means: 2-character indentation per level, no tabs, no lines over 80 characters. I/O is done via the C-style stdio library, style class header files should not import any system headers, STL containers should be avoided in headers, and forward declarations used where possible or needed. All added code should be placed into the LAMMPS_NS namespace or a sub-namespace; global or static variables should be avoided, as they conflict with the modular nature of LAMMPS and the C++ class structure. There MUST NOT be any "using namespace XXX;" statements in headers. In the implementation file (<name>.cpp) system includes should be placed in angular brackets (<>) and for c-library functions the C++ style header files should be included (<cstdio> instead of <stdio.h>, or <cstring> instead of <string.h>). This all is so the developers can more easily understand, integrate, and maintain your contribution and reduce conflicts with other parts of LAMMPS. This basically means that the code accesses data structures, performs its operations, and is formatted similar to other LAMMPS source files, including the use of the error class for error and warning messages.
* Source, style name, and documentation file should follow the following naming convention: style names should be lowercase and words separated by a forward slash; for a new fix style 'foo/bar', the class should be named FixFooBar, the name of the source files should be 'fix_foo_bar.h' and 'fix_foo_bar.cpp' and the corresponding documentation should be in a file 'fix_foo_bar.txt'.
* For consistency with the rest of LAMMPS and especially, if you want your contribution(s) to be added to main LAMMPS code or one of its standard packages, it needs to be written in a style compatible with other LAMMPS source files. This means: 2-character indentation per level, no tabs, no trailing whitespace, no lines over 80 characters. I/O is done via the C-style stdio library, style class header files should not import any system headers, STL containers should be avoided in headers, and forward declarations used where possible or needed.

* Source, style name, and documentation file should follow the following naming convention: style names should be lowercase and words separated by a forward slash; for a new fix style 'foo/bar', the class should be named FixFooBar, the name of the source files should be 'fix_foo_bar.h' and 'fix_foo_bar.cpp' and the corresponding documentation should be in a file 'fix_foo_bar.rst'.
* If you want your contribution to be added as a user-contributed feature, and it is a single file (actually a `<name>.cpp` and `<name>.h` file) it can be rapidly added to the USER-MISC directory. Include the one-line entry to add to the USER-MISC/README file in that directory, along with the 2 source files. You can do this multiple times if you wish to contribute several individual features.
* If you want your contribution to be added as a user-contribution and it is several related features, it is probably best to make it a user package directory with a name like USER-FOO. In addition to your new files, the directory should contain a README text file. The README should contain your name and contact information and a brief description of what your new package does. If your files depend on other LAMMPS style files also being installed (e.g. because your file is a derived class from the other LAMMPS class), then an Install.sh file is also needed to check for those dependencies. See other README and Install.sh files in other USER directories as examples. Send us a tarball of this USER-FOO directory.
* Your new source files need to have the LAMMPS copyright, GPL notice, and your name and email address at the top, like other user-contributed LAMMPS source files. They need to create a class that is inside the LAMMPS namespace. If the file is for one of the USER packages, including USER-MISC, then we are not as picky about the coding style (see above). I.e. the files do not need to be in the same stylistic format and syntax as other LAMMPS files, though that would be nice for developers as well as users who try to read your code.
* You **must** also create or extend a documentation file for each new command or style you are adding to LAMMPS. For simplicity and convenience, the documentation of groups of closely related commands or styles may be combined into a single file. This will be one file for a single-file feature. For a package, it might be several files. These are simple text files with a specific markup language, that are then auto-converted to HTML and PDF. The tools for this conversion are included in the source distribution, and the translation can be as simple as doing "make html pdf" in the doc folder. Thus the documentation source files must be in the same format and style as other `<name>.txt` files in the lammps/doc/src directory for similar commands and styles; use one or more of them as a starting point. A description of the markup can also be found in `lammps/doc/utils/txt2html/README.html` As appropriate, the text files can include links to equations (see doc/Eqs/*.tex for examples, we auto-create the associated JPG files), or figures (see doc/JPG for examples), or even additional PDF files with further details (see doc/PDF for examples). The doc page should also include literature citations as appropriate; see the bottom of doc/fix_nh.txt for examples and the earlier part of the same file for how to format the cite itself. The "Restrictions" section of the doc page should indicate that your command is only available if LAMMPS is built with the appropriate USER-MISC or USER-FOO package. See other user package doc files for examples of how to do this. The prerequisite for building the HTML format files are Python 3.x and virtualenv, the requirement for generating the PDF format manual is the htmldoc software. Please run at least "make html" and carefully inspect and proofread the resulting HTML format doc page before submitting your code.
* You **must** also create or extend a documentation file for each new command or style you are adding to LAMMPS. For simplicity and convenience, the documentation of groups of closely related commands or styles may be combined into a single file. This will be one file for a single-file feature. For a package, it might be several files. These are files in the [reStructuredText](https://docutils.sourceforge.io/rst.html) markup language, that are then converted to HTML and PDF. The tools for this conversion are included in the source distribution, and the translation can be as simple as doing "make html pdf" in the doc folder. Thus the documentation source files must be in the same format and style as other `<name>.rst` files in the lammps/doc/src directory for similar commands and styles; use one or more of them as a starting point. An introduction to reStructuredText can be found at [https://docutils.sourceforge.io/docs/user/rst/quickstart.html](https://docutils.sourceforge.io/docs/user/rst/quickstart.html). The text files can include mathematical expressions and symbol in ".. math::" sections or ":math:" expressions or figures (see doc/JPG for examples), or even additional PDF files with further details (see doc/PDF for examples). The doc page should also include literature citations as appropriate; see the bottom of doc/fix_nh.rst for examples and the earlier part of the same file for how to format the cite itself. The "Restrictions" section of the doc page should indicate that your command is only available if LAMMPS is built with the appropriate USER-MISC or USER-FOO package. See other user package doc files for examples of how to do this. The prerequisite for building the HTML format files are Python 3.x and virtualenv. Please run at least `make html`, `make pdf` and `make spelling` and carefully inspect and proofread the resulting HTML format doc page as well as the output produced to the screen. Make sure that all spelling errors are fixed or the necessary false positives are added to the `doc/utils/sphinx-config/false_positives.txt` file. For new styles, those usually also need to be added to lists on the respective overview pages. This can be checked for also with `make style_check`.
* For a new package (or even a single command) you should include one or more example scripts demonstrating its use. These should run in no more than a couple minutes, even on a single processor, and not require large data files as input. See directories under examples/USER for examples of input scripts other users provided for their packages. These example inputs are also required for validating memory accesses and testing for memory leaks with valgrind
* If there is a paper of yours describing your feature (either the algorithm/science behind the feature itself, or its initial usage, or its implementation in LAMMPS), you can add the citation to the *.cpp source file. See src/USER-EFF/atom_vec_electron.cpp for an example. A LaTeX citation is stored in a variable at the top of the file and a single line of code that references the variable is added to the constructor of the class. Whenever a user invokes your feature from their input script, this will cause LAMMPS to output the citation to a log.cite file and prompt the user to examine the file. Note that you should only use this for a paper you or your group authored. E.g. adding a cite in the code for a paper by Nose and Hoover if you write a fix that implements their integrator is not the intended usage. That kind of citation should just be in the doc page you provide.

Serial vs parallel build
-------------------------------------
------------------------
LAMMPS can be built to run in parallel using the ubiquitous `MPI (message-passing interface) <https://en.wikipedia.org/wiki/Message_Passing_Interface>`_
library. Or it can built to run on a single processor (serial)
without MPI. It can also be built with support for OpenMP threading
(see more discussion below).
LAMMPS is written to use the ubiquitous `MPI (Message Passing Interface)
<https://en.wikipedia.org/wiki/Message_Passing_Interface>`_ library API
for distributed memory parallel computation. You need to have such a
library installed for building and running LAMMPS in parallel using a
domain decomposition parallelization. It is compatible with the MPI
standard version 2.x and later. LAMMPS can also be built into a
"serial" executable for use with a single processor using the bundled
MPI STUBS library.
**CMake variables**\ :
Independent of the distributed memory MPI parallelization, parts of
LAMMPS are also written with support for shared memory parallelization
using the `OpenMP <https://en.wikipedia.org/wiki/OpenMP>`_ threading
standard. A more detailed discussion of that is below.
**CMake build**\ :
.. parsed-literal::
.. code-block:: bash
-D BUILD_MPI=value # yes or no, default is yes if CMake finds MPI, else no
-D BUILD_OMP=value # yes or no (default)
-D BUILD_OMP=value # yes or no, default is yes if a compatible compiler is detected
-D LAMMPS_MACHINE=name # name = mpi, serial, mybox, titan, laptop, etc
# no default value
The executable created by CMake (after running make) is lmp\_name. If
the LAMMPS\_MACHINE variable is not specified, the executable is just
lmp. Using BUILD\_MPI=no will produce a serial executable.
The executable created by CMake (after running make) is named ``lmp`` unless
the ``LAMMPS_MACHINE`` option is set. When setting ``LAMMPS_MACHINE=name``
the executable will be called ``lmp_name``. Using ``BUILD_MPI=no`` will
enforce building a serial executable using the MPI STUBS library.
**Traditional make**\ :
The build with traditional makefiles has to be done inside the source folder ``src``.
.. parsed-literal::
.. code-block:: bash
cd lammps/src
make mpi # parallel build, produces lmp_mpi using Makefile.mpi
make serial # serial build, produces lmp_serial using Makefile/serial
make mybox # uses Makefile.mybox to produce lmp_mybox
make mybox # uses Makefile.mybox to produce lmp_mybox
Serial build (see src/MAKE/Makefile.serial):
Any ``make machine`` command will look up the make settings from a file
``Makefile.machine`` in the folder ``src/MAKE`` or one of its
sub-directories ``MINE``, ``MACHINES``, or ``OPTIONS``, create a folder
``Obj_machine`` with all objects and generated files and an executable
called ``lmp_machine``\ . The standard parallel build with ``make mpi``
assumes a standard MPI installation with MPI compiler wrappers where all
necessary compiler and linker flags to get access and link with the
suitable MPI headers and libraries are set by the wrapper programs. For
other cases or the serial build, you have to adjust the make file
variables ``MPI_INC``, ``MPI_PATH``, ``MPI_LIB`` as well as ``CC`` and
``LINK``\ . To enable OpenMP threading usually a compiler specific flag
needs to be added to the compile and link commands. For the GNU
compilers, this is ``-fopenmp``\ , which can be added to the ``CC`` and
``LINK`` makefile variables.
For the serial build the following make variables are set (see src/MAKE/Makefile.serial):
.. parsed-literal::
.. code-block:: make
CC = g++
LINK = g++
MPI_INC = -I../STUBS
MPI_PATH = -L../STUBS
MPI_LIB = -lmpi_stubs
For a parallel build, if MPI is installed on your system in the usual
place (e.g. under /usr/local), you do not need to specify the 3
variables MPI\_INC, MPI\_PATH, MPI\_LIB. The MPI wrapper on the compiler
(e.g. mpicxx, mpiCC) knows where to find the needed include and
library files. Failing this, these 3 variables can be used to specify
where the mpi.h file (MPI\_INC), and the MPI library files (MPI\_PATH)
are found, and the name of the library files (MPI\_LIB).
You also need to build the STUBS library for your platform before making
LAMMPS itself. A ``make serial`` build does this for you automatically,
otherwise, type ``make mpi-stubs`` from the src directory, or ``make``
from the ``src/STUBS`` dir. If the build fails, you may need to edit
the ``STUBS/Makefile`` for your platform. The stubs library does not
provide MPI/IO functions required by some LAMMPS packages,
e.g. ``MPIIO`` or ``USER-LB``, and thus is not compatible with those
packages.
For a serial build, you need to specify the 3 variables, as shown
above.
.. note::
For a serial LAMMPS build, use the dummy MPI library provided in
src/STUBS. You also need to build the STUBS library for your platform
before making LAMMPS itself. A "make serial" build does this for.
Otherwise, type "make mpi-stubs" from the src directory, or "make"
from the src/STUBS dir. If the build fails, you will need to edit the
STUBS/Makefile for your platform.
The file ``src/STUBS/mpi.c`` provides a CPU timer function called
``MPI_Wtime()`` that calls ``gettimeofday()``. If your operating system
does not support ``gettimeofday()``, you will need to insert code to
call another timer. Note that the ANSI-standard function ``clock()``
rolls over after an hour or so, and is therefore insufficient for
timing long LAMMPS simulations.
The file STUBS/mpi.c provides a CPU timer function called MPI\_Wtime()
that calls gettimeofday() . If your system doesn't support
gettimeofday() , you'll need to insert code to call another timer.
Note that the ANSI-standard function clock() rolls over after an hour
or so, and is therefore insufficient for timing long LAMMPS
simulations.
**MPI and OpenMP support info**\ :
**CMake and make info**\ :
If you are installing MPI yourself to build a parallel LAMMPS
executable, we recommend either MPICH or OpenMPI which are regularly
used and tested with LAMMPS by the LAMMPS developers. MPICH can be
downloaded from the `MPICH home page <https://www.mpich.org>`_ and
OpenMPI can be downloaded correspondingly from the `OpenMPI home page
<https://www.open-mpi.org>`_. Other MPI packages should also work. No
specific vendor provided and standard compliant MPI library is currently
known to be incompatible with LAMMPS. If you are running on a large
parallel machine, your system admins or the vendor should have already
installed a version of MPI, which is likely to be faster than a
self-installed MPICH or OpenMPI, so you should study the provided
documentation to find out how to build and link with it.
If you are installing MPI yourself, we recommend MPICH2 from Argonne
National Laboratory or OpenMPI. MPICH can be downloaded from the
`Argonne MPI site <http://www.mcs.anl.gov/research/projects/mpich2/>`_.
OpenMPI can be downloaded from the `OpenMPI site <http://www.open-mpi.org>`_. Other MPI packages should also work.
If you are running on a large parallel machine, your system admins or
the vendor should have already installed a version of MPI, which is
likely to be faster than a self-installed MPICH or OpenMPI, so find
out how to build and link with it.
The majority of OpenMP (threading) support in LAMMPS is provided by the
``USER-OMP`` package; see the :doc:`Speed omp <Speed_omp>` doc page for
details. The ``USER-INTEL`` package also includes OpenMP threading (it
is compatible with ``USER-OMP`` and will usually fall back on styles
from that package, if a ``USER-INTEL`` does not exist) and adds
vectorization support when compiled with compatible compilers, in
particular the Intel compilers on top of OpenMP. Also, the ``KOKKOS``
package can be compiled to include OpenMP threading.

In addition, there are a few commands in LAMMPS that have native OpenMP
support included as well. These are commands in the ``MPIIO``,
``SNAP``, ``USER-DIFFRACTION``, and ``USER-DPD`` packages. In addition
some packages support OpenMP threading indirectly through the libraries
they interface to: e.g. ``LATTE``, ``KSPACE``, and ``USER-COLVARS``.
See the :doc:`Packages details <Packages_details>` doc page for more
info on these packages and the doc pages for their respective commands
for OpenMP threading info.

variable before you launch LAMMPS.
For building via conventional make, the CCFLAGS and LINKFLAGS
For building via conventional make, the ``CCFLAGS`` and ``LINKFLAGS``
variables in Makefile.machine need to include the compiler flag that
enables OpenMP. For GNU compilers it is -fopenmp. For (recent) Intel
compilers it is -qopenmp. If you are using a different compiler,
enables OpenMP. For GNU compilers it is ``-fopenmp``\ . For (recent) Intel
compilers it is ``-qopenmp``\ . If you are using a different compiler,
please refer to its documentation.
.. _default-none-issues:
**OpenMP Compiler compatibility info**\ :
Some compilers do not fully support the 'default(none)' directive
and others (e.g. GCC version 9 and beyond) may implement OpenMP 4.0
semantics, which are incompatible with the OpenMP 3.1 directives used
in LAMMPS (for maximal compatibility with compiler versions in use).
In those case, all 'default(none)' directives (which aid in detecting
incorrect and unwanted sharing) can be replaced with 'default(shared)'
while dropping all 'shared()' directives. The script
'src/USER-OMP/hack\_openmp\_for\_pgi\_gcc9.sh' can be used to automate
this conversion.
**OpenMP Compiler compatibility info**\ :
Some compilers do not fully support the ``default(none)`` directive
and others (e.g. GCC version 9 and beyond, Clang version 10 and later)
may implement strict OpenMP 4.0 and later semantics, which are incompatible
with the OpenMP 3.1 semantics used in LAMMPS for maximal compatibility
with compiler versions in use. If compilation with OpenMP enabled fails
because of your compiler requiring strict OpenMP 4.0 semantic, you can
change the behavior by adding ``-D LAMMPS_OMP_COMPAT=4`` to the ``LMP_INC``
variable in your makefile, or add it to the command line while configuring
with CMake. CMake will detect the suitable setting for the GNU, Clang,
and Intel compilers.

.. _compile:
Choice of compiler and compile/link options
---------------------------------------------------------
The choice of compiler and compiler flags can be important for
performance. Vendor compilers can produce faster code than
open-source compilers like GNU. On boxes with Intel CPUs, we suggest
trying the `Intel C++ compiler <intel_>`_.
The choice of compiler and compiler flags can be important for maximum
performance. Vendor provided compilers for a specific hardware can
produce faster code than open-source compilers like the GNU compilers.
On the most common x86 hardware most popular C++ compilers are quite
similar in performance of C/C++ code at high optimization levels. When
using the ``USER-INTEL`` package, there is a distinct advantage in using
the `Intel C++ compiler <intel_>`_ due to much improved vectorization
through SSE and AVX instructions on compatible hardware as the source
code includes changes and Intel compiler specific directives to enable
high degrees of vectorization. This may change over time as equivalent
vectorization directives are included into OpenMP standard revisions and
other compilers adopt them.

``CMAKE_TUNE_FLAGS`` variable that can be set to apply global compiler
options. More on that below, but you can also specify the corresponding
``CMAKE_*_FLAGS`` variables individually if you want to experiment with
alternate optimization flags. You should specify all 3 compilers, so
that the (few) LAMMPS source files written in C or Fortran are built
with a compiler consistent with the one used for the C++ files:

compilers this would be ``-xHost`` and for GNU compilers this would be
``-march=native``. To turn these flags off, do ``-D CMAKE_TUNE_FLAGS=``.

.. _exe:
Build LAMMPS as an executable or a library
----------------------------------------------------
Build the LAMMPS executable and library
---------------------------------------
LAMMPS can be built as either an executable or as a static or shared
library. The LAMMPS library can be called from another application or
a scripting language. See the :doc:`Howto couple <Howto_couple>` doc
LAMMPS is always built as a library of C++ classes plus an executable.
The executable is a simple ``main()`` function that sets up MPI and then
creates a LAMMPS class instance from the LAMMPS library, which
will then process commands provided via a file or from the console
input. The LAMMPS library can also be called from another application
or a scripting language. See the :doc:`Howto couple <Howto_couple>` doc
page for more info on coupling LAMMPS to other codes. See the
:doc:`Python <Python_head>` doc page for more info on wrapping and
running LAMMPS from Python via its library interface.
**CMake variables**\ :
**CMake build**\ :
For CMake builds, you can select through setting CMake variables between
building a shared or a static LAMMPS library and what kind of suffix is
added to them (in case you want to concurrently install multiple variants
of binaries with different settings). If none are set, defaults are applied.
.. parsed-literal::
.. code-block:: bash
-D BUILD_EXE=value # yes (default) or no
-D BUILD_LIB=value # yes or no (default)
-D BUILD_SHARED_LIBS=value # yes or no (default)
-D LAMMPS_LIB_SUFFIX=name # name = mpi, serial, mybox, titan, laptop, etc
-D LAMMPS_MACHINE=name # name = mpi, serial, mybox, titan, laptop, etc
# no default value
Setting BUILD\_EXE=no will not produce an executable. Setting
BUILD\_LIB=yes will produce a static library named liblammps.a.
Setting both BUILD\_LIB=yes and BUILD\_SHARED\_LIBS=yes will produce a
shared library named liblammps.so. If LAMMPS\_LIB\_SUFFIX is set the generated
libraries will be named liblammps\_name.a or liblammps\_name.so instead.
The compilation will always produce a LAMMPS library and an executable
linked to it. By default this will be a static library named
``liblammps.a`` and an executable named ``lmp`` Setting
``BUILD_SHARED_LIBS=yes`` will instead produce a shared library called
``liblammps.so`` (or ``liblammps.dylib`` or ``liblammps.dll`` depending
on the platform) If ``LAMMPS_MACHINE=name`` is set in addition, the name
of the generated libraries will be changed to either
``liblammps_name.a`` or ``liblammps_name.so``\ , respectively and the
executable will be called ``lmp_name``.
**Traditional make**\ :
With the traditional makefile based build process, the choice of
the generated executable or library depends on the "mode" setting.
Several options are available and ``mode=static`` is the default.
.. parsed-literal::
.. code-block:: bash
cd lammps/src
make machine # build LAMMPS executable lmp_machine
make mode=lib machine # build LAMMPS static lib liblammps_machine.a
make mode=shlib machine # build LAMMPS shared lib liblammps_machine.so
make mode=static machine # same as "make machine"
make mode=shared machine # build LAMMPS shared lib liblammps_machine.so instead
The two library builds also create generic soft links, named
liblammps.a and liblammps.so, which point to the liblammps\_machine
files.
The "static" build will generate a static library called
``liblammps_machine.a`` and an executable named ``lmp_machine``\ , while
the "shared" build will generate a shared library
``liblammps_machine.so`` instead and ``lmp_machine`` will be linked to
it. The build step will also create generic soft links, named
``liblammps.a`` and ``liblammps.so``\ , which point to the specific
``liblammps_machine.a/so`` files.
**CMake and make info**\ :
Note that for a shared library to be usable by a calling program, all
the auxiliary libraries it depends on must also exist as shared
libraries. This will be the case for libraries included with LAMMPS,
such as the dummy MPI library in src/STUBS or any package libraries in
the lib/packages directory, since they are always built as shared
libraries using the -fPIC switch. However, if a library like MPI or
FFTW does not exist as a shared library, the shared library build will
generate an error. This means you will need to install a shared
library version of the auxiliary library. The build instructions for
the library should tell you how to do this.
Note that for creating a shared library, all the libraries it depends on
must be compiled to be compatible with shared libraries. This should be
the case for libraries included with LAMMPS, such as the dummy MPI
library in ``src/STUBS`` or any package libraries in the ``lib``
directory, since they are always built in a shared library compatible
way using the ``-fPIC`` compiler switch. However, if an auxiliary
library (like MPI or FFTW) does not exist as a compatible format, the
shared library linking step may generate an error. This means you will
need to install a compatible version of the auxiliary library. The
build instructions for that library should tell you how to do this.
As an example, here is how to build and install the `MPICH library <mpich_>`_, a popular open-source version of MPI, distributed by
Argonne National Lab, as a shared library in the default
/usr/local/lib location:

.. _mpich: https://www.mpich.org
.. parsed-literal::
.. code-block:: bash
./configure --enable-shared
make
make install
You may need to use "sudo make install" in place of the last line if
you do not have write privileges for /usr/local/lib. The end result
should be the file /usr/local/lib/libmpich.so.
You may need to use ``sudo make install`` in place of the last line if
you do not have write privileges for ``/usr/local/lib`` or use the
``--prefix`` configuration option to select an installation folder,
where you do have write access. The end result should be the file
``/usr/local/lib/libmpich.so``. On many Linux installations the folder
``${HOME}/.local`` is an alternative to using ``/usr/local`` and does
not require superuser or sudo access. In that case the configuration
step becomes:
.. code-block:: bash
./configure --enable-shared --prefix=${HOME}/.local
Avoiding to use "sudo" for custom software installation (i.e. from source
and not through a package manager tool provided by the OS) is generally
recommended to ensure the integrity of the system software installation.
----------
.. _debug:
Excluding or removing debug support
-----------------------------------
By default the compilation settings will include the *-g* flag which
instructs the compiler to include debug information (e.g. which line of
source code a particular instruction correspond to). This can be
extremely useful in case LAMMPS crashes and can help to provide crucial
information in :doc:`tracking down the origin of a crash <Errors_debug>`
and help the LAMMPS developers fix bugs in the source code. However,
this increases the storage requirements for object files, libraries, and
the executable 3-5 fold.
If this is a concern, you can change the compilation settings or remove
the debug information from the LAMMPS executable:
- **Traditional make**: edit your ``Makefile.<machine>`` to remove the
*-g* flag from the ``CCFLAGS`` and ``LINKFLAGS`` definitions
- **CMake**: use ``-D CMAKE_BUILD_TYPE=Release`` or explicitly reset
the applicable compiler flags (best done using the text mode or
graphical user interface).
- **Remove debug info**: If you are only concerned about the executable
being too large, you can use the ``strip`` tool (e.g. ``strip
lmp_serial``) to remove the debug information from the executable file.
Do not strip libraries or object files, as that will render them unusable.
----------
.. _doc:
Build the LAMMPS documentation
----------------------------------------
**CMake variable**\ :
The LAMMPS manual is written in `reStructuredText <rst_>`_ format which
can be translated to different output format using the `Sphinx <sphinx_>`_
document generator tool. Currently the translation to HTML and PDF (via
LaTeX) are supported. For that to work a Python 3 interpreter and
internet access is required. For the documentation build a python
based virtual environment is set up in the folder doc/docenv and various
python packages are installed into that virtual environment via the pip
tool. The actual translation is then done via make commands.
.. _rst: https://docutils.readthedocs.io/en/sphinx-docs/user/rst/quickstart.html
.. _sphinx: https://sphinx-doc.org
.. parsed-literal::
**Documentation make option**\ :
-D BUILD_DOC=value # yes or no (default)
The following make commands can be issued in the doc folder of the
LAMMPS source distribution.
This will create the HTML doc pages within the CMake build directory.
The reason to do this is if you want to "install" LAMMPS on a system
after the CMake build via "make install", and include the doc pages in
the install.
.. code-block:: bash
**Traditional make**\ :
make html # create HTML doc pages in html directory
make pdf # create Developer.pdf and Manual.pdf in this directory
make fetch # fetch HTML and PDF files from LAMMPS web site
make clean # remove all intermediate files
make clean-all # reset the entire doc build environment
make anchor_check # scan for duplicate anchor labels
make style_check # check for complete and consistent style lists
make package_check # check for complete and consistent package lists
make spelling # spell-check the manual
.. parsed-literal::
cd lammps/doc
make html # html doc pages
make pdf # single Manual.pdf file
This will create a lammps/doc/html dir with the HTML doc pages so that
you can browse them locally on your system. Type "make" from the
lammps/doc dir to see other options.
Thus "make html" will create a "doc/html" directory with the HTML format
manual pages so that you can browse them with a web browser locally on
your system.

current LAMMPS version (HTML and PDF files), from the website
`download page <http://lammps.sandia.gov/download.html>`_.

**CMake build option**\ :
It is also possible to create the HTML version of the manual within
the :doc:`CMake build directory <Build_cmake>`. The reason for this
option is to include the installation of the HTML manual pages into
the "install" step when installing LAMMPS after the CMake build via
``make install``. The documentation build is included in the default

Build LAMMPS with CMake
=======================
This page is a short summary of how to use CMake to build LAMMPS.
Details on CMake variables that enable specific LAMMPS build options
are given on the pages linked to from the :doc:`Build <Build>` doc page.
This page describes how to use `CMake <https://cmake.org>`_ in general
to build LAMMPS. Details for specific compile time settings and options
to enable and configure add-on packages are discussed with those
packages. Links to those pages on the :doc:`Build overview <Build>`
page.
Richard Berger (Temple U) has also written a `more comprehensive guide <https://github.com/lammps/lammps/blob/master/cmake/README.md>`_
for how to use CMake to build LAMMPS. If you are new to CMake it is a
good place to start.
The following text assumes some familiarity with CMake and focuses on
using the command line tool ``cmake`` and what settings are supported
for building LAMMPS. A more detailed tutorial on how to use ``cmake``
itself, the text mode or graphical user interface, change the generated
output files for different build tools and development environments is
on a :doc:`separate page <Howto_cmake>`.
.. note::
LAMMPS currently requires that CMake version 3.10 or later is available;
version 3.12 or later is preferred.
.. warning::
You must not mix the :doc:`traditional make based <Build_make>`
LAMMPS build procedure with using CMake. Thus no packages may be
installed or a build been previously attempted in the LAMMPS source
directory by using ``make <machine>``. CMake will detect if this is
the case and generate an error. To remove conflicting files from the
``src`` you can use the command ``make no-all purge`` which will
un-install all packages and delete all auto-generated files.
----------
Advantages of using CMake
^^^^^^^^^^^^^^^^^^^^^^^^^
CMake is an alternative to compiling LAMMPS in the traditional way
through :doc:`(manually customized) makefiles <Build_make>` and a recent
addition to LAMMPS thanks to the efforts of Christoph Junghans (LANL)
and Richard Berger (Temple U). Using CMake has multiple advantages that
are specifically helpful for people with limited experience in compiling
software or for people that want to modify or extend LAMMPS.
- CMake can detect available hardware, tools, features, and libraries
and adapt the LAMMPS default build configuration accordingly.
- CMake can generate files for different build tools and integrated
development environments (IDE).
- CMake supports customization of settings with a text mode or graphical
user interface. No knowledge of file formats or and complex command
line syntax required.
- All enabled components are compiled in a single build operation.
- Automated dependency tracking for all files and configuration options.
- Support for true out-of-source compilation. Multiple configurations
and settings with different choices of LAMMPS packages, settings, or
compilers can be configured and built concurrently from the same
source tree.
- Simplified packaging of LAMMPS for Linux distributions, environment
modules, or automated build tools like `Homebrew <https://brew.sh/>`_.
- Integration of automated regression testing (the LAMMPS side for that
is still under development).
.. _cmake_build:
Getting started
^^^^^^^^^^^^^^^
Building LAMMPS with CMake is a two-step process. First you use CMake
to create a build environment in a new directory. On Linux systems,
this will be based on makefiles for use with make. Then you use the
make command to build LAMMPS, which uses the created
Makefile(s). Example:
to generate a build environment in a new directory. For that purpose
you can use either the command-line utility ``cmake`` (or ``cmake3``),
the text-mode UI utility ``ccmake`` (or ``ccmake3``) or the graphical
utility ``cmake-gui``, or use them interchangeably. The second step is
then the compilation and linking of all objects, libraries, and
executables. Here is a minimal example using the command line version of
CMake to build LAMMPS with no add-on packages enabled and no
customization:
.. code-block:: bash
.. parsed-literal::
cd lammps # change to the LAMMPS distribution directory
mkdir build; cd build # create and use a build directory
cmake ../cmake # configuration reading CMake scripts from ../cmake
cmake --build . # compilation (or type "make")
cd lammps # change to the LAMMPS distribution directory
mkdir build; cd build # create a new directory (folder) for build
cmake [options ...] ../cmake # configuration with (command-line) cmake
make # compilation
This will create and change into a folder called ``build``, then run the
configuration step to generate build files for the default build command
and then launch that build command to compile LAMMPS. During the
configuration step CMake will try to detect whether support for MPI,
OpenMP, FFTW, gzip, JPEG, PNG, and ffmpeg are available and enable the
corresponding configuration settings. The progress of this
configuration can be followed on the screen and a summary of selected
options and settings will be printed at the end. The ``cmake --build
.`` command will launch the compilation, which, if successful, will
ultimately produce a library ``liblammps.a`` and the LAMMPS executable
``lmp`` inside the ``build`` folder.
The cmake command will detect available features, enable selected
packages and options, and will generate the build environment. By default
this build environment will be created for "Unix Makefiles" on most
platforms and particularly on Linux. However, alternate build tools
(e.g. Ninja) and support files for Integrated Development Environments
(IDE) like Eclipse, CodeBlocks, or Kate can be generated, too. This is
selected via the "-G" command line flag. For the rest of the documentation
we will assume that the build environment is generated for makefiles
and thus the make command will be used to compile and link LAMMPS as
indicated above, producing (by default) an executable called "lmp" and
a library called "liblammps.a" in the "build" folder. When generating
a build environment for the "Ninja" build tool, the build command would
be "ninja" instead of "make".
Compilation can take a long time, since LAMMPS is a large project with
many features. If your machine has multiple CPU cores (most do these
days), you can speed this up by compiling sources in parallel with
``make -j N`` (with N being the maximum number of concurrently executed
tasks). Also installation of the `ccache <https://ccache.dev/>`_ (=
Compiler Cache) software may speed up repeated compilation even more,
e.g. during code development.
If your machine has multiple CPU cores (most do these days), using a
command like "make -jN" (with N being the number of available local
CPU cores) can be much faster. If you plan to do development on
LAMMPS or need to re-compile LAMMPS repeatedly, installation of the
ccache (= Compiler Cache) software may speed up repeated compilation
even more.
After the initial build, whenever you edit LAMMPS source files, enable
or disable packages, change compiler flags or build options, you must
re-compile and relink the LAMMPS executable with ``cmake --build .`` (or
``make``). If the compilation fails for some reason, try running
``cmake .`` and then compile again. The included dependency tracking
should make certain that only the necessary subset of files are
re-compiled. You can also delete compiled objects, libraries and
executables with ``cmake --build . clean`` (or ``make clean``).
After compilation, you may optionally install the LAMMPS executable into
your system with:
.. code-block:: bash
.. parsed-literal::
make install # optional, copy compiled files into installation location
make install # optional, copy LAMMPS executable & library elsewhere
This will install the LAMMPS executable and library, some tools (if
configured) and additional files like LAMMPS API headers, manpages,
potential and force field files. The location of the installation tree
defaults to ``${HOME}/.local``.
This will install the lammps executable and library (if requested), some
tools (if configured) and additional files like library API headers,
manpages, potential and force field files. The location of the installation
tree is set by the CMake variable "CMAKE\_INSTALL\_PREFIX" which defaults
to ${HOME}/.local
.. _cmake_options:
Configuration and build options
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The CMake commands have one mandatory argument: a folder containing a
file called ``CMakeLists.txt`` (for LAMMPS it is located in the
``cmake`` folder) or a build folder containing a file called
``CMakeCache.txt``, which is generated at the end of the CMake
configuration step. The cache file contains all current CMake settings.
To modify settings, enable or disable features, you need to set *variables*
with either the *-D* command line flag (``-D VARIABLE1_NAME=value``) or
change them in the text mode of graphical user interface. The *-D* flag
can be used several times in one command.
For your convenience we provide :ref:`CMake presets <cmake_presets>`
that combine multiple settings to enable optional LAMMPS packages or use
a different compiler tool chain. Those are loaded with the *-C* flag
(``-C ../cmake/presets/minimal.cmake``). This step would only be needed
once, as the settings from the preset files are stored in the
``CMakeCache.txt`` file. It is also possible to customize the build
by adding one or more *-D* flags to the CMake command line.
Generating files for alternate build tools (e.g. Ninja) and project files
for IDEs like Eclipse, CodeBlocks, or Kate can be selected using the *-G*
command line flag. A list of available generator settings for your
specific CMake version is given when running ``cmake --help``.
----------
There are 3 variants of CMake: a command-line version (cmake), a text mode
UI version (ccmake), and a graphical GUI version (cmake-GUI). You can use
any of them interchangeably to configure and create the LAMMPS build
environment. On Linux all the versions produce a Makefile as their
output. See more details on each below.
You can specify a variety of options with any of the 3 versions, which
affect how the build is performed and what is included in the LAMMPS
executable. Links to pages explaining all the options are listed on
the :doc:`Build <Build>` doc page.
You must perform the CMake build system generation and compilation in
a new directory you create. It can be anywhere on your local machine.
In these Build pages we assume that you are building in a directory
called "lammps/build". You can perform separate builds independently
with different options, so long as you perform each of them in a
separate directory you create. All the auxiliary files created by one
build process (executable, object files, log files, etc) are stored in
this directory or sub-directories within it that CMake creates.
.. note::
To perform a CMake build, no packages can be installed or a
build been previously attempted in the LAMMPS src directory by using
"make" commands to :doc:`perform a conventional LAMMPS build <Build_make>`. CMake detects if this is the case and
generates an error, telling you to type "make no-all purge" in the src
directory to un-install all packages. The purge removes all the \*.h
files auto-generated by make.
You must have CMake version 2.8 or later on your system to build
LAMMPS. A handful of LAMMPS packages (KOKKOS, LATTE, MSCG) require a
later version. CMake will print a message telling you if a later
version is required. Installation instructions for CMake are below.
After the initial build, if you edit LAMMPS source files, or add your
own new files to the source directory, you can just re-type make from
your build directory and it will re-compile only the files that have
changed. If you want to change CMake options you can run cmake (or
ccmake or cmake-gui) again from the same build directory and alter
various options; see details below. Or you can remove the entire build
folder, recreate the directory and start over.
----------
**Command-line version of CMake**\ :
.. parsed-literal::
cmake [options ...] /path/to/lammps/cmake # build from any dir
cmake [options ...] ../cmake # build from lammps/build
The cmake command takes one required argument, which is the LAMMPS
cmake directory which contains the CMakeLists.txt file.
The argument can be preceeded or followed by various CMake
command-line options. Several useful ones are:
.. parsed-literal::
-D CMAKE_INSTALL_PREFIX=path # where to install LAMMPS executable/lib if desired
-D CMAKE_BUILD_TYPE=type # type = RelWithDebInfo (default), Release, MinSizeRel, or Debug
-G output # style of output CMake generates
-DVARIABLE=value # setting for a LAMMPS feature to enable
-D VARIABLE=value # ditto, but cannot come after CMakeLists.txt dir
-C path/to/preset/file # load some CMake settings before configuring
All the LAMMPS-specific -D variables that a LAMMPS build supports are
described on the pages linked to from the :doc:`Build <Build>` doc page.
All of these variable names are upper-case and their values are
lower-case, e.g. -D LAMMPS\_SIZES=smallbig. For boolean values, any of
these forms can be used: yes/no, on/off, 1/0.
On Unix/Linux machines, CMake generates a Makefile by default to
perform the LAMMPS build. Alternate forms of build info can be
generated via the -G switch, e.g. Visual Studio on a Windows machine,
Xcode on MacOS, or KDevelop on Linux. Type "cmake --help" to see the
"Generator" styles of output your system supports.
.. note::
When CMake runs, it prints configuration info to the screen.
You should review this to verify all the features you requested were
enabled, including packages. You can also see what compilers and
compile options will be used for the build. Any errors in CMake
variable syntax will also be flagged, e.g. mis-typed variable names or
variable values.
CMake creates a CMakeCache.txt file when it runs. This stores all the
settings, so that when running CMake again you can use the current
folder '.' instead of the path to the LAMMPS cmake folder as the
required argument to the CMake command. Either way the existing
settings will be inherited unless the CMakeCache.txt file is removed.
If you later want to change a setting you can rerun cmake in the build
directory with different setting. Please note that some automatically
detected variables will not change their value when you rerun cmake.
In these cases it is usually better to first remove all the
files/directories in the build directory, or start with a fresh build
directory.
----------
**Curses version (terminal-style menu) of CMake**\ :
.. parsed-literal::
ccmake ../cmake
You initiate the configuration and build environment generation steps
separately. For the first you have to type **c**\ , for the second you
have to type **g**\ . You may need to type **c** multiple times, and may be
required to edit some of the entries of CMake configuration variables
in between. Please see the `ccmake manual <https://cmake.org/cmake/help/latest/manual/ccmake.1.html>`_ for
more information.
----------
**GUI version of CMake**\ :
.. parsed-literal::
cmake-gui ../cmake
You initiate the configuration and build environment generation steps
separately. For the first you have to click on the **Configure** button,
for the second you have to click on the **Generate** button. You may
need to click on **Configure** multiple times, and may be required to
edit some of the entries of CMake configuration variables in between.

Development build options (CMake only)

The CMake build procedure of LAMMPS offers a few extra options which are
useful during development, testing or debugging.
----------
.. _compilation:
Verify compilation flags
------------------------------------------
------------------------
Sometimes it is necessary to verify the complete sequence of compilation flags
generated by the CMake build. To enable a more verbose output during
compilation you can use the following option.
.. parsed-literal::
.. code-block:: bash
-D CMAKE_VERBOSE_MAKEFILE=value # value = no (default) or yes

Address, Undefined Behavior, and Thread Sanitizer Support
-------------------------------------------------------------------------

Compilers such as GCC and Clang support generating binaries which use different
sanitizers to detect problems in code during run-time. They can detect `memory leaks <https://clang.llvm.org/docs/AddressSanitizer.html>`_,
code that runs into `undefined behavior <https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html>`_ of the
language and `data races <https://clang.llvm.org/docs/ThreadSanitizer.html>`_ in threaded code.
Compilers such as GCC and Clang support generating instrumented binaries
which use different sanitizer libraries to detect problems in code

The following settings allow you enable these features if your compiler supports
it. Please note that they come with a performance hit. However, they are
usually faster than using tools like Valgrind.

- `undefined behavior <https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html>`_
- `data races <https://clang.llvm.org/docs/ThreadSanitizer.html>`_
Please note that this kind of instrumentation usually comes with a small
performance hit (much less than using tools like `Valgrind
<https://valgrind.org>`_). The to enable these features additional
compiler flags need to be added to the compilation and linking stages.
This is most easily done through setting the ``CMAKE_TUNE_FLAGS``
variable during configuration. Examples:
.. parsed-literal::
-D ENABLE_SANITIZE_ADDRESS=value # enable Address Sanitizer, value = no (default) or yes
-D ENABLE_SANITIZE_UNDEFINED=value # enable Undefined Behaviour Sanitizer, value = no (default) or yes
-D ENABLE_SANITIZE_THREAD=value # enable Thread Sanitizer, value = no (default) or yes
.. code-block:: bash
-D CMAKE_TUNE_FLAGS=-fsanitize=address # enable address sanitizer / memory leak checker

Link LAMMPS as a library to another code
========================================
LAMMPS can be used as a library by another application, including
Python scripts. The files src/library.cpp and library.h define the
C-style API for using LAMMPS as a library. See the :doc:`Howto library <Howto_library>` doc page for a description of the
interface and how to extend it for your needs.
LAMMPS is designed as a library of C++ objects and can thus be
integrated into other applications including Python scripts.
The files ``src/library.cpp`` and ``src/library.h`` define a
C-style API for using LAMMPS as a library. See the :doc:`Howto
library <Howto_library>` doc page for a description of the interface
and how to extend it for your needs.
The :doc:`Build basics <Build_basics>` doc page explains how to build
LAMMPS as either a shared or static library. This results in one of
these 2 files:
LAMMPS as either a shared or static library. This results in a file
in the compilation folder called ``liblammps.a`` or ``liblammps_<name>.a``
in case of building a static library. In case of a shared library
the name is the same only that the suffix is going to be either ``.so``
or ``.dylib`` or ``.dll`` instead of ``.a`` depending on the OS.
In some cases the ``.so`` file may be a symbolic link to a file with
the suffix ``.so.0`` (or some other number).
liblammps.so # shared library
liblammps.a # static library
.. note::
Care should be taken to use the same MPI library for the calling code
and the LAMMPS library. The ``library.h`` file includes ``mpi.h``
and uses definitions from it so those need to be available and
consistent. When LAMMPS is compiled with the included STUBS MPI
library, then its ``mpi.h`` file needs to be included. While it is
technically possible to use a full MPI library in the calling code
and link to a serial LAMMPS library compiled with MPI STUBS, it is
recommended to use the *same* MPI library for both, and then use
``MPI_Comm_split()`` in the calling code to pass a suitable
communicator with a subset of MPI ranks to the function creating the
LAMMPS instance.
----------
**Link with LAMMPS as a static library**\ :
The calling application can link to LAMMPS as a static library with a
link command like this:
The calling application can link to LAMMPS as a static library with
compilation and link commands as in the examples shown below. These
are examples for a code written in C in the file *caller.c*.
The benefit of linking to a static library is, that the resulting
executable is independent of that library since all required
executable code from the library is copied into the calling executable.
g++ caller.o -L/home/sjplimp/lammps/src -llammps -o caller
*CMake build*\ :
The -L argument is the path to where the liblammps.a file is. The
-llammps argument is shorthand for the file liblammps.a.
This assumes that LAMMPS has been configured without setting a
``LAMMPS_MACHINE`` name, installed with "make install", and the
``PKG_CONFIG_PATH`` environment variable has been updated to include the
``liblammps.pc`` file installed into the configured destination folder.
The commands to compile and link a coupled executable are then:
.. code-block:: bash
mpicc -c -O $(pkgconf liblammps --cflags) caller.c
mpicxx -o caller caller.o -$(pkgconf liblammps --libs)
*Traditional make*\ :
This assumes that LAMMPS has been compiled in the folder
``${HOME}/lammps/src`` with "make mpi". The commands to compile and link
a coupled executable are then:
.. code-block:: bash
mpicc -c -O -I${HOME}/lammps/src caller.c
mpicxx -o caller caller.o -L${HOME}/lammps/src -llammps_mpi
The *-I* argument is the path to the location of the ``library.h``
header file containing the interface to the LAMMPS C-style library
interface. The *-L* argument is the path to where the ``liblammps_mpi.a``
file is located. The *-llammps_mpi* argument is shorthand for telling the
compiler to link the file ``liblammps_mpi.a``. If LAMMPS has been
built as a shared library, then the linker will use ``liblammps_mpi.so``
instead. If both files are available, the linker will usually prefer
the shared library. In case of a shared library, you may need to update
the ``LD_LIBRARY_PATH`` environment variable or running the ``caller``
executable will fail since it cannot find the shared library at runtime.
However, it is only as simple as shown above for the case of a plain
LAMMPS library without any optional packages that depend on libraries
(bundled or external) or when using a shared library. Otherwise, you
need to include all flags, libraries, and paths for the coupled
executable, that are also required to link the LAMMPS executable.
*CMake build*\ :
When using CMake, additional libraries with sources in the lib folder
are built, but not included in ``liblammps.a`` and (currently) not
installed with "make install" and not included in the *pkgconfig*
configuration file. They can be found in the top level build folder,
but you have to determine the necessary link flags manually. It is
therefore recommended to either use the traditional make procedure to
build and link with a static library or build and link with a shared
library instead.
.. TODO: this needs to be updated to reflect that latest CMake changes after they are complete.
*Traditional make*\ :
After you have compiled a static LAMMPS library using the conventional
build system for example with "make mode=static serial". And you also
have installed the ``POEMS`` package after building its bundled library
in ``lib/poems``. Then the commands to build and link the coupled executable
change to:
.. code-block:: bash
gcc -c -O -I${HOME}/lammps/src/STUBS -I${HOME}/lammps/src -caller.c
g++ -o caller caller.o -L${HOME}/lammps/lib/poems \
-L${HOME}/lammps/src/STUBS -L${HOME}/lammps/src -llammps_serial -lpoems -lmpi_stubs
Note, that you need to link with "g++" instead of "gcc", since the
LAMMPS library is C++ code. You can display the currently applied
settings for building LAMMPS for the "serial" machine target by using
the command:
.. code-block:: bash
make mode=print serial
Which should output something like:
.. code-block:: bash
# Compiler:
CXX=g++
# Linker:
LD=g++
# Compilation:
CXXFLAGS=-g -O3 -DLAMMPS_GZIP -DLAMMPS_MEMALIGN=64 -I${HOME}/compile/lammps/lib/poems -I${HOME}/compile/lammps/src/STUBS
# Linking:
LDFLAGS=-g -O
# Libraries:
LDLIBS=-L${HOME}/compile/lammps/src -llammps_serial -L${HOME}/compile/lammps/lib/poems -L${HOME}/compile/lammps/src/STUBS -lpoems -lmpi_stubs
From this you can gather the necessary paths and flags. With
makefiles for other *machine* configurations you need to do the
equivalent and replace "serial" with the corresponding *machine* name
of the makefile.
----------
**Link with LAMMPS as a shared library**\ :
If you wish to link to liblammps.so, the operating system finds shared
libraries to load at run-time using the environment variable
LD\_LIBRARY\_PATH. To enable this you can do one of two things:
When linking to LAMMPS built as a shared library, the situation becomes
much simpler, as all dependent libraries and objects are either included
in the shared library or registered as a dependent library in the shared
library file. Thus those libraries need not to be specified when
linking the calling executable. Only the *-I* flags are needed. So the
example case from above of the serial version static LAMMPS library with
the POEMS package installed becomes:
(1) Copy the liblammps.so file to a location the system can find it,
such as /usr/local/lib. I.e. a directory already listed in your
LD\_LIBRARY\_PATH variable. You can type
*CMake build*\ :
The commands with a shared LAMMPS library compiled with the CMake
build process are the same as for the static library.
.. parsed-literal::
.. code-block:: bash
mpicc -c -O $(pkgconf liblammps --cflags) caller.c
mpicxx -o caller caller.o -$(pkgconf --libs)
*Traditional make*\ :
The commands with a shared LAMMPS library compiled with the
traditional make build using "make mode=shared serial" becomes:
.. code-block:: bash
gcc -c -O -I${HOME}/lammps/src/STUBS -I${HOME}/lammps/src -caller.c
g++ -o caller caller.o -L${HOME}/lammps/src -llammps_serial
*Locating liblammps.so at runtime*\ :
However, now the ``liblammps.so`` file is required at runtime and needs
to be in a folder, where the shared linker program of the operating
system can find it. This would be either a folder like ``/usr/local/lib64``
or ``${HOME}/.local/lib64`` or a folder pointed to by the ``LD_LIBRARY_PATH``
environment variable. You can type
.. code-block:: bash
printenv LD_LIBRARY_PATH
to see what directories are in that list.
(2) Add the LAMMPS src directory (or the directory you perform CMake
build in) to your LD\_LIBRARY\_PATH, so that the current version of the
shared library is always available to programs that use it.
Or you can add the LAMMPS src directory (or the directory you performed
a CMake style build in) to your ``LD_LIBRARY_PATH``, so that the current
version of the shared library is always available to programs that use it.
For the csh or tcsh shells, you would add something like this to your
~/.cshrc file:
For the Bourne or Korn shells (/bin/sh, /bin/ksh, /bin/bash etc.), you
would add something like this to your ``${HOME}/.profile`` file:
.. code-block:: bash
.. parsed-literal::
LD_LIBRARY_PATH ${LD_LIBRARY_PATH-/usr/lib64}:${HOME}/lammps/src
export LD_LIBRARY_PATH
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/home/sjplimp/lammps/src
For the csh or tcsh shells, you would equivalently add something like this
to your ``${HOME}/.cshrc`` file:
.. code-block:: csh
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${HOME}/lammps/src
You can verify whether all required shared libraries are found with the
``ldd`` tool. Example:
.. code-block:: bash
$ LD_LIBRARY_PATH=/home/user/lammps/src ldd caller
linux-vdso.so.1 (0x00007ffe729e0000)
liblammps.so => /home/user/lammps/src/liblammps.so (0x00007fc91bb9e000)
libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007fc91b984000)
libm.so.6 => /lib64/libm.so.6 (0x00007fc91b83e000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fc91b824000)

/lib64/ld-linux-x86-64.so.2 (0x00007fc91c094000)
If a required library is missing, you would get a 'not found' entry:
.. code-block:: bash
$ ldd caller
linux-vdso.so.1 (0x00007ffd672fe000)
liblammps.so => not found
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007fb7c7e86000)
libm.so.6 => /usr/lib64/libm.so.6 (0x00007fb7c7d40000)

**Calling the LAMMPS library**\ :
Either flavor of library (static or shared) allows one or more LAMMPS
objects to be instantiated from the calling program.
objects to be instantiated from the calling program. When used from a
C++ program, most of the symbols and functions in LAMMPS are wrapped
in a ``LAMMPS_NS`` namespace; you can safely use any of its classes and
methods from within the calling code, as needed, and you will not incur
conflicts with functions and variables in your code that share the name.
This, however, does not extend to all additional libraries bundled with
LAMMPS in the lib folder and some of the low-level code of some packages.

======================
Building LAMMPS with traditional makefiles requires that you have a
Makefile."machine" file appropriate for your system in the src/MAKE,
src/MAKE/MACHINES, src/MAKE/OPTIONS, or src/MAKE/MINE directory (see
below). It can include various options for customizing your LAMMPS
build with a number of global compilation options and features.
``Makefile.<machine>`` file appropriate for your system in either the
``src/MAKE``, ``src/MAKE/MACHINES``, ``src/MAKE/OPTIONS``, or
``src/MAKE/MINE`` directory (see below). It can include various options
for customizing your LAMMPS build with a number of global compilation
options and features.
To include LAMMPS packages (i.e. optional commands and styles) you
must install them first, as discussed on the :doc:`Build package <Build_package>` doc page. If the packages require
provided or external libraries, you must build those libraries before
building LAMMPS. Building :doc:`LAMMPS with CMake <Build_cmake>` can
automate all of this for many types of machines, especially
workstations, desktops and laptops, so we suggest you try it first.
Requirements
^^^^^^^^^^^^
These commands perform a default LAMMPS build, producing the LAMMPS
executable lmp\_serial or lmp\_mpi in lammps/src:
Those makefiles are written for and tested with GNU make and may not
be compatible with other make programs. In most cases, if the "make"
program is not GNU make, then there will be a GNU make program
available under the name "gmake". If GNU make or a compatible make is
not available, you may have to first install it or switch to building
with :doc:`CMake <Build_cmake>`. The makefiles of the traditional
make based build process and the scripts they are calling expect a few
additional tools to be available and functioning.
* a working C/C++ compiler toolchain supporting the C++11 standard; on
Linux these are often the GNU compilers. Some older compilers
require adding flags like ``-std=c++11`` to enable the C++11 mode.
* a Bourne shell compatible "Unix" shell program (often this is ``bash``)
* a few shell utilities: ``ls``, ``mv``, ``ln``, ``rm``, ``grep``, ``sed``, ``tr``, ``cat``, ``touch``, ``diff``, ``dirname``
* python (optional, required for ``make lib-<pkg>`` in the src folder).
python scripts are currently tested with python 2.7 and 3.6. The procedure
for :doc:`building the documentation <Manual_build>` requires python 3.

Getting started
^^^^^^^^^^^^^^^
cd lammps/src
make serial # build a serial LAMMPS executable
To include LAMMPS packages (i.e. optional commands and styles) you must
enable (or "install") them first, as discussed on the :doc:`Build
package <Build_package>` doc page. If a packages requires (provided or
external) libraries, you must configure and build those libraries
**before** building LAMMPS itself and especially **before** enabling
such a package with ``make yes-<package>``. Building :doc:`LAMMPS with
CMake <Build_cmake>` can automate much of this for many types of
machines, especially workstations, desktops, and laptops, so we suggest
you try it first when building LAMMPS in those cases.
The commands below perform a default LAMMPS build, producing the LAMMPS
executable ``lmp_serial`` and ``lmp_mpi`` in ``lammps/src``:
.. code-block:: bash
cd lammps/src # change to main LAMMPS source folder
make serial # build a serial LAMMPS executable using GNU g++
make mpi # build a parallel LAMMPS executable with MPI
make # see a variety of make options
This initial compilation can take a long time, since LAMMPS is a large
project with many features. If your machine has multiple CPU cores
(most do these days), using a command like "make -jN mpi" (with N =
the number of available CPU cores) can be much faster. If you plan to
do development on LAMMPS or need to re-compile LAMMPS repeatedly, the
installation of the ccache (= Compiler Cache) software may speed up
compilation even more.
Compilation can take a long time, since LAMMPS is a large project with
many features. If your machine has multiple CPU cores (most do these
days), you can speed this up by compiling sources in parallel with
``make -j N`` (with N being the maximum number of concurrently executed
tasks). Also installation of the `ccache <https://ccache.dev/>`_ (=
Compiler Cache) software may speed up repeated compilation even more,
e.g. during code development.
After the initial build, whenever you edit LAMMPS source files, or add
or remove new files to the source directory (e.g. by installing or
uninstalling packages), you must re-compile and relink the LAMMPS
executable with the same "make" command. This makefiles dependencies
should insure that only the subset of files that need to be are
re-compiled.
executable with the same ``make <machine>`` command. The makefile's
dependency tracking should insure that only the necessary subset of
files are re-compiled. If you change settings in the makefile, you have
to recompile *everything*. To delete all objects you can use ``make
clean-<machine>``.
.. note::
When you build LAMMPS for the first time, a long list of \*.d
files will be printed out rapidly. This is not an error; it is the
Makefile doing its normal creation of dependencies.
Before the actual compilation starts, LAMMPS will perform several
steps to collect information from the configuration and setup that
is then embedded into the executable. When you build LAMMPS for
the first time, it will also compile a tool to quickly assemble
a list of dependencies, that are required for the make program to
correctly detect which parts need to be recompiled after changes
were made to the sources.
Customized builds and alternate makefiles
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
----------
The ``src/MAKE`` directory tree contains the ``Makefile.<machine>``
files included in the LAMMPS distribution. Typing ``make example`` uses
``Makefile.example`` from one of those folders, if available. Thus the
``make serial`` and ``make mpi`` lines above use
``src/MAKE/Makefile.serial`` and ``src/MAKE/Makefile.mpi``,
respectively. Other makefiles are in these directories:
The lammps/src/MAKE tree contains all the Makefile.machine files
included in the LAMMPS distribution. Typing "make machine" uses
Makefile.machine. Thus the "make serial" or "make mpi" lines above
use Makefile.serial and Makefile.mpi. Others are in these dirs:
.. parsed-literal::
.. code-block:: bash
OPTIONS # Makefiles which enable specific options
MACHINES # Makefiles for specific machines
MINE # customized Makefiles you create (you may need to create this folder)
Typing "make" lists all the available Makefile.machine files. A file
with the same name can appear in multiple folders (not a good idea).
The order the dirs are searched is as follows: src/MAKE/MINE,
src/MAKE, src/MAKE/OPTIONS, src/MAKE/MACHINES. This gives preference
to a customized file you put in src/MAKE/MINE.
Simply typing ``make`` lists all the available ``Makefile.<machine>``
files with a single line description toward the end of the output. A

``src/MAKE/MACHINES``. This gives preference to a customized file you
put in ``src/MAKE/MINE``. If you create your own custom makefile under
a new name, please edit the first line with the description and machine
name, so you will not confuse yourself, when looking at the machine
summary.

C++11 standard compliance test
C++11 standard compliance
------------------------------------------
The LAMMPS developers plan to transition to make the C++11 standard the
minimum requirement for compiling LAMMPS. Currently this only applies to
some packages like KOKKOS while the rest aims to be compatible with the C++98
standard. Most currently used compilers are compatible with C++11; some need
to set extra flags to switch. To determine the impact of requiring C++11,
we have added a simple compliance test to the source code, that will cause
the compilation to abort, if C++11 compliance is not available or enabled.
To bypass this check, you need to change a setting in the makefile or
when calling CMake.
A C++11 standard compatible compiler is a requirement for compiling LAMMPS.
LAMMPS version 3 March 2020 is the last version compatible with the previous
C++98 standard for the core code and most packages. Most currently used
C++ compilers are compatible with C++11, but some older ones may need extra
flags to enable C++11 compliance. Example for GNU c++ 4.8.x:
**CMake variable**\ :
.. parsed-literal::
-D DISABLE_CXX11_REQUIREMENT=yes
You can set additional C++ compiler flags (beyond those selected by CMake)
