llvmpy: Python bindings for LLVM

Home page

http://www.llvmpy.org

Versions

This package has been tested with LLVM 3.2, Python 2.6, 2.7 and 3.3. Other Python versions may work.

Quickstart

1. Get and extract LLVM 3.2 source tarball from llvm.org. Then, cd into the extracted directory.

2. Run ./configure --enable-optimized --prefix=LLVM_INSTALL_PATH.

   Note: Without the --enable-optimized flag, debug build will be selected. Unless you are developing LLVM or llvmpy, it is recommended that the flag is used to reduce build time and binary size.

   Note: Use prefix to select the installation path. It is recommended to separate your custom build from the default system package. Please replace LLVM_INSTALL_PATH with your own path.

3. Run REQUIRES_RTTI=1 make to build.

   Note: With LLVM 3.2, the default build configuration has C++ RTTI disabled. However, llvmpy requires RTTI.

4. Get llvm-py and install it:

   $ git clone git@github.com:llvmpy/llvmpy.git
   $ cd llvmpy
   $ LLVM_CONFIG_PATH=LLVM_INSTALL_PATH/bin/llvm-config python setup.py install
   

   Run the tests:

   $ python -c "import llvm; llvm.test()"
   

5. See documentation at 'http://www.llvmpy.org' and examples under 'test'.

Common Build Problems

1. If llvmpy cannot be imported due to "undefined symbol: _ZTIN4llvm24PassRegistrationListenerE", it is because RTTI is not enabled when building LLVM. "_ZTIN4llvm24PassRegistrationListenerE" is the typeinfo of PassRegistrationListener class.
