This package has been tested with LLVM 3.2, Python 2.6, 2.7 and 3.3. Other Python versions may work.
- Get and extract LLVM 3.2 source tarball from llvm.org. Then,
cd
into the extracted directory. 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.Run
REQUIRES_RTTI=1 make install
to build and install.Note: With LLVM 3.2, the default build configuration has C++ RTTI disabled. However, llvmpy requires RTTI.
Note: Use
make -j2 install
to enable concurrent build. Replace2
with the actual number of processor you have.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()"
- See documentation at 'http://www.llvmpy.org' and examples under 'test'.
- 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.
- LLVM3.3 ssize_t mismatch on 64-bit Windows. Get patch from http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130701/180049.html
