<div class="postcontent">
|
||||
<h2>Preliminaries</h2>
|
||||
<p>LLDB relies on many of the technologies developed by the larger LLVM project.
|
||||
In particular, it requires both Clang and LLVM itself in order to build. Due to
|
||||
this tight integration the <em>Getting Started</em> guides for both of these projects
|
||||
come as prerequisite reading:</p>
|
||||
<ul>
|
||||
<li><a href="http://llvm.org/docs/GettingStarted.html">LLVM</a></li>
|
||||
<li><a href="http://clang.llvm.org/get_started.html">Clang</a></li>
|
||||
</ul>
|
||||
<p>Supported compilers for building LLDB on Linux include:</p>
|
||||
<ul>
|
||||
<li>Clang 3.2</li>
|
||||
<li><a href="http://gcc.gnu.org">GCC</a> 4.6.2 (later versions should work as well)</li>
|
||||
</ul>
|
||||
<p>It is recommended to use libstdc++ 4.6 (or higher) to build LLDB on Linux, but using libc++ is also known to work.</p>
|
||||
<p>On FreeBSD the base system Clang and libc++ may be used to build LLDB,
|
||||
or the GCC port or package.</p>
|
||||
<p>In addition to any dependencies required by LLVM and Clang, LLDB needs a few
|
||||
development packages that may also need to be installed depending on your
|
||||
system. The current list of dependencies are:</p>
|
||||
<ul>
|
||||
<li><a href="http://swig.org">Swig</a></li>
|
||||
<li><a href="http://www.thrysoee.dk/editline">libedit</a> (Linux only)</li>
|
||||
<li><a href="http://www.python.org">Python</a></li>
|
||||
</ul>
|
||||
<p>So for example, on a Fedora system one might run:</p>
|
||||
<code>> yum install swig python-devel libedit-devel</code>
|
||||
<p>On a Debian or Ubuntu system one might run:</p>
|
||||
<code>> sudo apt-get install build-essential subversion swig python2.7-dev libedit-dev libncurses5-dev </code>
|
||||
<p>or</p>
|
||||
<code>> sudo apt-get build-dep lldb-3.3 # or lldb-3.4</code>
|
||||
<p>On FreeBSD one might run:</p>
|
||||
<code>> pkg install swig python</code>
|
||||
<p>If you wish to build the optional reference documentation, additional dependencies are required:</p>
|
||||
<ul>
|
||||
<li> Graphviz (for the 'dot' tool).
|
||||
<li> doxygen (only if you wish to build the C++ API reference)
|
||||
<li> epydoc (only if you wish to build the Python API reference)
|
||||
</ul>
|
||||
<p>To install the prerequisites for building the documentation (on Debian/Ubuntu) do:</p>
|
||||
<code>
|
||||
<br>> sudo apt-get install doxygen graphviz
|
||||
<br>> sudo pip install epydoc # or install package python-epydoc
|
||||
</code>
|
||||
<h2 >Building LLDB</h2>
|
||||
<p>We first need to checkout the source trees into the appropriate locations. Both
|
||||
Clang and LLDB build as subprojects of LLVM. This means we will be checking out
|
||||
the source for both Clang and LLDB into the <tt>tools</tt> subdirectory of LLVM. We

will be setting up a directory hierarchy looking something like this:</p>

<h2>Building LLDB</h2>
|
||||
<p>
|
||||
We first need to checkout the source trees into the appropriate locations. Both
|
||||
Clang and LLDB build as subprojects of LLVM. This means we will be checking out
|
||||
the source for both Clang and LLDB into the <tt>tools</tt> subdirectory of LLVM. We
|
||||
will be setting up a directory hierarchy looking something like this:

|
|||
|
|
||||
`-- lldb
|
||||
</tt></pre>
|
||||
</p>
|
||||
<p>For reference, we will call the root of the LLVM project tree <tt>$llvm</tt>, and the
|
||||
roots of the Clang and LLDB source trees <tt>$clang</tt> and <tt>$lldb</tt> respectively.</p>
|
||||
<p>Change to the directory where you want to do development work and checkout LLVM:</p>
|
||||
<code>> svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm</code>
|
||||
|
||||
<p>Now switch to LLVM’s tools subdirectory and checkout both Clang and LLDB:</p>
|
||||
<code>> cd $llvm/tools
|
||||
<br>> svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
|
||||
<br>> svn co http://llvm.org/svn/llvm-project/lldb/trunk lldb
|
||||
</code>
|
||||
|
||||
<p>In general, building the LLDB trunk revision requires trunk revisions of both
|
||||
LLVM and Clang.
|
||||
<p>It is highly recommended that you build the system out of tree. Create a second
|
||||
build directory and configure the LLVM project tree to your specifications as
|
||||
outlined in LLVM’s <em>Getting Started Guide</em>. A typical build procedure
|
||||
might be:</p>
|
||||
<code>> cd $llvm/..
|
||||
<br>> mkdir build
|
||||
<br>> cd build
|
||||
</code>
|
||||
<h2>To build with CMake</h2>
|
||||
<p>Using CMake is documented on the <a href="http://llvm.org/docs/CMake.html">Building LLVM with CMake</a>
|
||||
page. Building LLDB is possible using one of the following generators:
|
||||
</p>
|
||||
<ul>
|
||||
<li> Ninja </li>
|
||||
<li> Unix Makefiles </li>
|
||||
</ul>
|
||||
<h3>Using CMake + Ninja</h3>
|
||||
<p>Ninja is the fastest way to build LLDB! In order to use ninja, you need to have recent versions of CMake and
|
||||
ninja on your system. To build using ninja:
|
||||
</p>
|
||||
<code>
|
||||
> cmake .. -G Ninja
|
||||
<br>> ninja lldb
|
||||
<br>> ninja check-lldb
|
||||
</code>
|
||||
<h3>Using CMake + Unix Makefiles</h3>
|
||||
<p>If you do not have Ninja, you can still use CMake to generate Unix Makefiles that build LLDB:</p>
|
||||
<code>
|
||||
> cmake ..
|
||||
<br>> make
|
||||
<br>> make check-lldb
|
||||
</code>
|
||||
<h2>To build with autoconf</h2>
|
||||
<p>If you do not have CMake, it is still possible to build LLDB using the autoconf build system. If you are using
|
||||
Clang or GCC 4.8+, run:</p>
|
||||
<code>
|
||||
> $llvm/configure
|
||||
<br>> make </code>
|
||||
<p>If you are building with a GCC that isn't the default gcc/g++, like gcc-4.9/g++-4.9</p>
|
||||
<code>
|
||||
> $llvm/configure CC=gcc-4.9 CXX=g++-4.9
|
||||
<br>> make CC=gcc-4.9 CXX=g++-4.9</code>
|
||||
<p>If you are running in a system that doesn't have a lot of RAM (less than 4GB), you might want to disable
|
||||
debug symbols by specifying DEBUG_SYMBOLS=0 when running make. You will know if you need to enable this
|
||||
because you will fail to link clang (the linker will get a SIGKILL and exit with status 9).</p>
|
||||
<code>
|
||||
> make DEBUG_SYMBOLS=0</code>
|
||||
<p> To run the LLDB test suite, run:</p>
|
||||
<code>
|
||||
<br>> make -C tools/lldb/test</code>
|
||||
<p>Note that once both LLVM and Clang have been configured and built it is not
|
||||
necessary to perform a top-level <tt>make</tt> to rebuild changes made only to LLDB.
|
||||
You can run <tt>make</tt> from the <tt>build/tools/lldb</tt> subdirectory as well.</p>
|
||||
<p> If you wish to build with libc++ instead of libstdc++ (the default), run configure with the
|
||||
<tt>--enable-libcpp</tt> flag.</p>
|
||||
<p> If you wish to build a release version of LLDB, run configure with the <tt>--enable-optimized</tt> flag.</p>
|
||||
</p>
|
||||
<p>
|
||||
For reference, we will call the root of the LLVM project tree <tt>$llvm</tt>, and the
|
||||
roots of the Clang and LLDB source trees <tt>$clang</tt> and <tt>$lldb</tt> respectively.
|
||||
</p>
|
||||
<p>Change to the directory where you want to do development work and checkout LLVM:</p>
|
||||
<code>> svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm</code>
|
||||
|
||||
<h2>Testing</h2>
|
||||
<p>By default, the <tt>check-lldb</tt> target builds the 64-bit variants of the test programs with the same
|
||||
compiler that was used to build LLDB. It is possible to customize the architecture and compiler by appending -A and
|
||||
-C options respectively to the CMake variable <tt>LLDB_TEST_ARGS</tt>. For example, to test LLDB against 32-bit binaries
|
||||
built with a custom version of clang, do:</p>
|
||||
<code>
|
||||
<br>> cmake -DLLDB_TEST_ARGS="-A i386 -C /path/to/custom/clang" -G Ninja
|
||||
<br>> ninja check-lldb
|
||||
</code>
|
||||
<p>Note that multiple -A and -C flags can be specified to <tt>LLDB_TEST_ARGS</tt>.</p>
|
||||
<p>In addition to running all the LLDB test suites with the "check-lldb" CMake target above, it is possible to
|
||||
run individual LLDB tests. For example, to run the test cases defined in TestInferiorCrashing.py, run:</p>
|
||||
<code>
|
||||
<br>> cd $lldb/test
|
||||
<br>> python dotest.py --executable <path-to-lldb> -p TestInferiorCrashing.py
|
||||
</code>
|
||||
<p>In addition to running a test by name, it is also possible to specify a directory path to <tt>dotest.py</tt>
|
||||
in order to run all the tests under that directory. For example, to run all the tests under the
|
||||
'functionalities/data-formatter' directory, run:</p>
|
||||
<code>
|
||||
<br>> python dotest.py --executable <path-to-lldb> functionalities/data-formatter
|
||||
</code>
|
||||
<p>To dump additional information to <tt>stdout</tt> about how the test harness is driving LLDB, run
|
||||
<tt>dotest.py</tt> with the <tt>-t</tt> flag. Many more options that are available. To see a list of all of them, run:</p>
|
||||
<code>
|
||||
<br>> python dotest.py -h
|
||||
</code>
|
||||
<h2>Building API reference documentation</h2>
|
||||
<p>LLDB exposes a C++ as well as a Python API. To build the reference documentation for these two APIs, ensure you have
|
||||
the required dependencies installed, and build the <tt>lldb-python-doc</tt> and <tt>lldb-cpp-doc</tt> CMake targets.</p>
|
||||
<p> The output HTML reference documentation can be found in <tt><build-dir>/tools/lldb/docs/</tt>.<p>
|
||||
<h2>Additional Notes</h2>
|
||||
<p>LLDB has a Python scripting capability and supplies its own Python module named <tt>lldb</tt>.
|
||||
If a script is run inside the command line <tt>lldb</tt> application, the Python module
|
||||
is made available automatically. However, if a script is to be run by a Python interpreter
|
||||
outside the command line application, the <tt>PYTHONPATH</tt> environment variable can be used
|
||||
to let the Python interpreter find the <tt>lldb</tt> module.
|
||||
<p>The correct path can be obtained by invoking the command line <tt>lldb</tt> tool with the -P flag:</p>
|
||||
<code>> export PYTHONPATH=`$llvm/build/Debug+Asserts/bin/lldb -P`</code>
|
||||
<p>If you used a different build directory or made a release build, you may need to adjust the
|
||||
above to suit your needs. To test that the lldb Python module
|
||||
is built correctly and is available to the default Python interpreter, run:</p>
|
||||
<code>> python -c 'import lldb'</code></p>

<p>Now switch to LLVM’s tools subdirectory and checkout both Clang and LLDB:</p>
|
||||
<code>
|
||||
> cd $llvm/tools
|
||||
<br />> svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
|
||||
<br />> svn co http://llvm.org/svn/llvm-project/lldb/trunk lldb
|
||||
</code>
|
||||
|
||||
<p>
|
||||
In general, building the LLDB trunk revision requires trunk revisions of both
|
||||
LLVM and Clang.
|
||||
</p>
|
||||
<p>
|
||||
It is highly recommended that you build the system out of tree. Create a second
|
||||
build directory and configure the LLVM project tree to your specifications as
|
||||
outlined in LLVM’s <em>Getting Started Guide</em>. A typical build procedure
|
||||
might be:
|
||||
</p>
|
||||
<code>
|
||||
> cd $llvm/..
|
||||
<br />> mkdir build
|
||||
<br />> cd build
|
||||
</code>
|
||||
<h2>To build with CMake</h2>
|
||||
<p>
|
||||
Using CMake is documented on the <a href="http://llvm.org/docs/CMake.html">Building LLVM with CMake</a>
|
||||
page. Building LLDB is possible using one of the following generators:
|
||||
</p>
|
||||
<ul>
|
||||
<li> Ninja </li>
|
||||
<li> Unix Makefiles </li>
|
||||
</ul>
|
||||
<h3>Using CMake + Ninja</h3>
|
||||
<p>
|
||||
Ninja is the fastest way to build LLDB! In order to use ninja, you need to have recent versions of CMake and
|
||||
ninja on your system. To build using ninja:
|
||||
</p>
|
||||
<code>
|
||||
> cmake .. -G Ninja
|
||||
<br />> ninja lldb
|
||||
<br />> ninja check-lldb
|
||||
</code>
|
||||
<h3>Using CMake + Unix Makefiles</h3>
|
||||
<p>If you do not have Ninja, you can still use CMake to generate Unix Makefiles that build LLDB:</p>
|
||||
<code>
|
||||
> cmake ..
|
||||
<br />> make
|
||||
<br />> make check-lldb
|
||||
</code>
|
||||
<h2>To build with autoconf</h2>
|
||||
<p>
|
||||
If you do not have CMake, it is still possible to build LLDB using the autoconf build system. If you are using
|
||||
Clang or GCC 4.8+, run:
|
||||
</p>
|
||||
<code>
|
||||
> $llvm/configure
|
||||
<br />> make
|
||||
</code>
|
||||
<p>If you are building with a GCC that isn't the default gcc/g++, like gcc-4.9/g++-4.9</p>
|
||||
<code>
|
||||
> $llvm/configure CC=gcc-4.9 CXX=g++-4.9
|
||||
<br />> make CC=gcc-4.9 CXX=g++-4.9
|
||||
</code>
|
||||
<p>
|
||||
If you are running in a system that doesn't have a lot of RAM (less than 4GB), you might want to disable
|
||||
debug symbols by specifying DEBUG_SYMBOLS=0 when running make. You will know if you need to enable this
|
||||
because you will fail to link clang (the linker will get a SIGKILL and exit with status 9).
|
||||
</p>
|
||||
<code>
|
||||
> make DEBUG_SYMBOLS=0
|
||||
</code>
|
||||
<p> To run the LLDB test suite, run:</p>
|
||||
<code>
|
||||
<br />> make -C tools/lldb/test
|
||||
</code>
|
||||
<p>
|
||||
Note that once both LLVM and Clang have been configured and built it is not
|
||||
necessary to perform a top-level <tt>make</tt> to rebuild changes made only to LLDB.
|
||||
You can run <tt>make</tt> from the <tt>build/tools/lldb</tt> subdirectory as well.
|
||||
</p>
|
||||
<p>
|
||||
If you wish to build with libc++ instead of libstdc++ (the default), run configure with the
|
||||
<tt>--enable-libcpp</tt> flag.
|
||||
</p>
|
||||
<p> If you wish to build a release version of LLDB, run configure with the <tt>--enable-optimized</tt> flag.</p>
|
||||
<h2>Testing</h2>
|
||||
<p>
|
||||
By default, the <tt>check-lldb</tt> target builds the 64-bit variants of the test programs with the same
|
||||
compiler that was used to build LLDB. It is possible to customize the architecture and compiler by appending -A and
|
||||
-C options respectively to the CMake variable <tt>LLDB_TEST_ARGS</tt>. For example, to test LLDB against 32-bit binaries
|
||||
built with a custom version of clang, do:
|
||||
</p>
|
||||
<code>
|
||||
<br />> cmake -DLLDB_TEST_ARGS="-A i386 -C /path/to/custom/clang" -G Ninja
|
||||
<br />> ninja check-lldb
|
||||
</code>
|
||||
<p>Note that multiple -A and -C flags can be specified to <tt>LLDB_TEST_ARGS</tt>.</p>
|
||||
<p>
|
||||
In addition to running all the LLDB test suites with the "check-lldb" CMake target above, it is possible to
|
||||
run individual LLDB tests. For example, to run the test cases defined in TestInferiorCrashing.py, run:
|
||||
</p>
|
||||
<code>
|
||||
<br />> cd $lldb/test
|
||||
<br />> python dotest.py --executable <path-to-lldb> -p TestInferiorCrashing.py
|
||||
</code>
|
||||
<p>
|
||||
In addition to running a test by name, it is also possible to specify a directory path to <tt>dotest.py</tt>
|
||||
in order to run all the tests under that directory. For example, to run all the tests under the
|
||||
'functionalities/data-formatter' directory, run:
|
||||
</p>
|
||||
<code>
|
||||
<br />> python dotest.py --executable <path-to-lldb> functionalities/data-formatter
|
||||
</code>
|
||||
<p>
|
||||
To dump additional information to <tt>stdout</tt> about how the test harness is driving LLDB, run
|
||||
<tt>dotest.py</tt> with the <tt>-t</tt> flag. Many more options that are available. To see a list of all of them, run:
|
||||
</p>
|
||||
<code>
|
||||
<br />> python dotest.py -h
|
||||
</code>
|
||||
<h2>Building API reference documentation</h2>
|
||||
<p>
|
||||
LLDB exposes a C++ as well as a Python API. To build the reference documentation for these two APIs, ensure you have
|
||||
the required dependencies installed, and build the <tt>lldb-python-doc</tt> and <tt>lldb-cpp-doc</tt> CMake targets.
|
||||
</p>
|
||||
<p> The output HTML reference documentation can be found in <tt><build-dir>/tools/lldb/docs/</tt>.</p><p>
|
||||
<h2>Additional Notes</h2>
|
||||
</p>
|
||||
<p>
|
||||
LLDB has a Python scripting capability and supplies its own Python module named <tt>lldb</tt>.
|
||||
If a script is run inside the command line <tt>lldb</tt> application, the Python module
|
||||
is made available automatically. However, if a script is to be run by a Python interpreter
|
||||
outside the command line application, the <tt>PYTHONPATH</tt> environment variable can be used
|
||||
to let the Python interpreter find the <tt>lldb</tt> module.
|
||||
</p>
|
||||
<p>The correct path can be obtained by invoking the command line <tt>lldb</tt> tool with the -P flag:</p>
|
||||
<code>> export PYTHONPATH=`$llvm/build/Debug+Asserts/bin/lldb -P`</code>
|
||||
<p>
|
||||
If you used a different build directory or made a release build, you may need to adjust the
|
||||
above to suit your needs. To test that the lldb Python module
|
||||
is built correctly and is available to the default Python interpreter, run:
|
||||
</p>
|
||||
<code>> python -c 'import lldb'</code></p>
