Getting Started
|
|
===============
|
|
|
|
On Mac OS, the easiest way to get this library is to link with -lSystem.
|
|
However if you want to build tip-of-trunk from here (getting the bleeding
|
|
edge), read on.
|
|
|
|
The basic steps needed to build libc++ are:
|
|
|
|
#. Checkout LLVM:
|
|
|
|
* ``cd where-you-want-llvm-to-live``
|
|
* ``svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm``
|
|
|
|
#. Checkout libunwind:
|
|
|
|
* ``cd where-you-want-llvm-to-live``
|
|
* ``cd llvm/runtimes``
|
|
* ``svn co http://llvm.org/svn/llvm-project/libunwind/trunk libunwind``
|
|
|
|
#. Configure and build libunwind:
|
|
|
|
CMake is the only supported configuration system.
|
|
|
|
Clang is the preferred compiler when building and using libunwind.
|
|
|
|
* ``cd where you want to build llvm``
|
|
* ``mkdir build``
|
|
* ``cd build``
|
|
* ``cmake -G <generator> [options] <path to llvm sources>``
|
|
|
|
For more information about configuring libunwind see :ref:`CMake Options`.
|
|
|
|
* ``make unwind`` --- will build libunwind.
|
|
* ``make check-unwind`` --- will run the test suite.
|
|
|
|
Shared and static libraries for libunwind should now be present in llvm/build/lib.
|
|
|
|
#. **Optional**: Install libunwind
|
|
|
|
If your system already provides an unwinder, it is important to be careful
|
|
not to replace it. Remember Use the CMake option ``CMAKE_INSTALL_PREFIX`` to
|
|
select a safe place to install libunwind.
|
|
|
|
* ``make install-unwind`` --- Will install the libraries and the headers
|
|
|
|
|
|
It is sometimes beneficial to build outside of the LLVM tree. An out-of-tree
|
|
build would look like this:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ cd where-you-want-libunwind-to-live
|
|
$ # Check out llvm, and libunwind
|
|
$ ``svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm``
|
|
$ ``svn co http://llvm.org/svn/llvm-project/libunwind/trunk libunwind``
|
|
$ cd where-you-want-to-build
|
|
$ mkdir build && cd build
|
|
$ export CC=clang CXX=clang++
|
|
$ cmake -DLLVM_PATH=path/to/llvm \
|
|
path/to/libunwind
|
|
$ make
|
|
|
|
|
|

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 libunwind.
|
