<p><a href="http://www.cmake.org/">CMake</a> is a cross-platform
|

build-generator tool. CMake does not build the project, it generates
|

|
|
the files needed by your build tool (GNU make, Visual Studio, etc) for
|
|||
|
|
building LLVM.</p>

<p> We use here the command-line, non-interactive CMake interface </p>

<ol>
|

|
|
|
|||
|
|
<li><p><a href=http://www.cmake.org/cmake/resources/software.html>Download</a>
|
|||
|
|
and install CMake. Version 2.6.2 is the minimum required.</p>
|
|||
|
|
|
|||
|
|
<li><p>Open a shell. Your development tools must be reachable from this
|
|||
|
|
shell through the PATH environment variable.</p>
|
|||
|
|
|
|||
|
|
<li><p>Create a directory for containing the build. It is not
|
|||
|
|
supported to build LLVM on the source directory. cd to this
|
|||
|
|
directory:</p>
|
|||
|
|
<div class="doc_code">
|
|||
|
|
<p><tt>mkdir mybuilddir</tt></p>
|
|||
|
|
<p><tt>cd mybuilddir</tt></p>
|
|||
|
|
</div>
|
|||
|
|
|
|||
|
|
<li><p>Execute this command on the shell
|
|||
|
|
replacing <i>path/to/llvm/source/root</i> with the path to the
|
|||
|
|
root of your LLVM source tree:</p>
|
|||
|
|
<div class="doc_code">
|
|||
|
|
<p><tt>cmake path/to/llvm/source/root</tt></p>
|
|||
|
|
</div>
|
|||
|
|
|
|||
|
|
<p>CMake will detect your development environment, perform a
|
|||
|
|
series of test and generate the files required for building
|
|||
|
|
LLVM. CMake will use default values for all build
|
|||
|
|
parameters. See the <a href="#options">Options and variables</a>
|
|||
|
|
section for fine-tuning your build</p>
|
|||
|
|
|
|||
|
|
<p>This can fail if CMake can't detect your toolset, or if it
|
|||
|
|
thinks that the environment is not sane enough. On this case
|
|||
|
|
make sure that the toolset that you intend to use is the only
|
|||
|
|
one reachable from the shell and that the shell itself is the
|
|||
|
|
correct one for you development environment. CMake will refuse
|
|||
|
|
to build MinGW makefiles if you have a POSIX shell reachable
|
|||
|
|
through the PATH environment variable, for instance. You can
|
|||
|
|
force CMake to use a given build tool, see
|
|||
|
|
the <a href="#usage">Usage</a> section.</p>

<p>Variables customize how the build will be generated. Options are

boolean variables, with possible values ON/OFF. Options and

variables are defined on the CMake command line like this:</p>

changing its value. You can also undefine a variable:</p>

<div class="doc_code">

<p>Variables are stored on the CMake cache. This is a file

named <it>CMakeCache.txt</it> on the root of the build

directory. Do not hand-edit it.</p>
