This directory contains links to the Eigen library which is required
|
||
|
|
to use the USER-SMD package in a LAMMPS input script.
|
||
|
|
|
||
|
|
The Eigen library is available at http://eigen.tuxfamily.org. It's
|
||
|
|
a general C++ template library for linear algebra.
|
||
|
|
|
||
|
|
You must perform the following steps yourself, or you can use the
|
||
|
|
install.py Python script to automate any or all steps of the process.
|
||
|
|
Type "python install.py" for instructions.
|
||
|
|
|
||
|
|
1. Download the Eigen tarball at http://eigen.tuxfamily.org and
|
||
|
|
unpack the tarball either in this /lib/smd directory or somewhere
|
||
|
|
else on your system. It should unpack with into a directory with
|
||
|
|
a name similar to eigen-eigen-bdd17ee3b1b3. Note that Eigen is a
|
||
|
|
template library, so you do not have to build it.
|
||
|
|
|
||
|
|
2. Create two soft links in this dir (lib/smd)
|
||
|
|
to the eigen directory. E.g if you unpacked Eigen in this dir:
|
||
|
|
% ln -s eigen-eigen-bdd17ee3b1b3 includelink
|
||
|
|
% ln -s eigen-eigen-bdd17ee3b1b3 liblink
|
||
|
|
If you unpackaged Eigen somewhere else and renamed
|
||
|
|
the directory to just eigen, then do something like this:
|
||
|
|
% ln -s /home/sjplimp/tools/eigen includelink
|
||
|
|
% ln -s /home/sjplimp/tools/eigen liblink
|
||
|
|
|
||
|
|
When these steps are complete you can build LAMMPS
|
||
|
|
with the USER-SMD package installed:
|
||
|
|
|
||
|
|
% cd lammps/src
|
||
|
|
% make yes-user-smd
|
||
|
|
% make g++ (or whatever target you wish)
|
||
|
|
|
||
|
|
Note that if you download and unpack a new LAMMPS tarball, the
|
||
|
|
"includelink" and "liblink" files will be lost and you will need to
|
||
|
|
re-create them (step 2). If you unpacked the Eigen library in this
|
||
|
|
directory (as opposed to somewhere else on your system), you will also
|
||
|
|
need to repeat step 1.
|
||
|
|
|
||
|
|
The Makefile.lammps file in this directory is there for compatibility
|
||
|
|
with the way other libraries under the lib dir are linked with by
|
||
|
|
LAMMPS. However, the Eigen library requires no auxiliary files or
|
||
|
|
settings, so its variables are blank.
