.. _BuildingCompilerRT:
===============
Building Compiler-RT
===============
.. contents::
:local:
.. _build instructions:
The instructions on this page are aimed at vendors who ship Compiler-RT as part of an
operating system distribution, a toolchain or similar shipping vehicules. If you
are a user merely trying to use Compiler-RT in your program, you most likely want to
refer to your vendor's documentation, or to the general documentation for using
LLVM, Clang, the various santizers, etc.
CMake Options
=============
Here are some of the CMake variables that are used often, along with a
brief explanation and LLVM-specific notes. For full documentation, check the
CMake docs or execute ``cmake --help-variable VARIABLE_NAME``.
**CMAKE_BUILD_TYPE**:STRING
Sets the build type for ``make`` based generators. Possible values are
Release, Debug, RelWithDebInfo and MinSizeRel. On systems like Visual Studio
the user sets the build type with the IDE settings.
**CMAKE_INSTALL_PREFIX**:PATH
Path where LLVM will be installed if "make install" is invoked or the
"INSTALL" target is built.
**CMAKE_CXX_COMPILER**:STRING
The C++ compiler to use when building and testing Compiler-RT.
.. _compiler-rt-specific options:
Compiler-RT specific options
-----------------------
.. option:: COMPILER_RT_INSTALL_PATH:PATH
**Default**: ```` (empty relative path)
Prefix for directories where built Compiler-RT artifacts should be installed.
Can be an absolute path, like the default empty string, in which case it is
relative ``CMAKE_INSTALL_PREFIX``. If setting a relative path, make sure to
include the ``:PATH`` with your ``-D``, i.e. use
``-DCOMPILER_RT_INSTALL_PATH:PATH=...`` not
``-DCOMPILER_RT_INSTALL_PATH=...``, otherwise CMake will convert the
path to an absolute path.
.. option:: COMPILER_RT_INSTALL_LIBRARY_DIR:PATH
**Default**: ``lib``
Path where built Compiler-RT libraries should be installed. If a relative
path, relative to ``COMPILER_RT_INSTALL_PATH``.
.. option:: COMPILER_RT_INSTALL_BINARY_DIR:PATH
**Default**: ``bin``
Path where built Compiler-RT executables should be installed. If a relative
path, relative to ``COMPILER_RT_INSTALL_PATH``.
.. option:: COMPILER_RT_INSTALL_INCLUDE_DIR:PATH
**Default**: ``include``
Path where Compiler-RT headers should be installed. If a relative
path, relative to ``COMPILER_RT_INSTALL_PATH``.
.. option:: COMPILER_RT_INSTALL_DATA_DIR:PATH
**Default**: ``share``
Path where Compiler-RT data should be installed. If a relative
path, relative to ``COMPILER_RT_INSTALL_PATH``.
.. _LLVM-specific variables:
LLVM-specific options
---------------------
.. option:: LLVM_LIBDIR_SUFFIX:STRING
Extra suffix to append to the directory where libraries are to be
installed. On a 64-bit architecture, one could use ``-DLLVM_LIBDIR_SUFFIX=64``
to install libraries to ``/usr/lib64``.
