Building and Installing Polly
Automatic
There is a script available to automatically checkout, update, build, and test Polly. This script contains all the commands that are subsequently described on this webpage. The automatic installation consists of four simple steps:mkdir polly && cd polly wget http://polly.llvm.org/polly.sh chmod +x polly.sh ./polly.sh
Manual
Get the code
Warning: Polly/LLVM/clang need to be checked out at the same time.
git clone http://llvm.org/git/llvm.git llvm_git git clone http://llvm.org/git/polly.git llvm_git/tools/polly # Also build the matching clang-version (optional) git clone http://llvm.org/git/clang.git llvm_git/tools/clang
Build Polly
mkdir llvm_build && cd llvm_build cmake ../llvm_git && make
Test Polly
make check-polly
Troubleshooting
If you get an error in one of the python files, your system probably uses python3
as default python interpreter. This is the case, for instance, under Arch Linux.
To solve this issue, run cmake
again, but with the added argument:
-DPYTHON_EXECUTABLE=/usr/bin/python2
(replace /usr/bin/python2
with the location of the python2 interpreter under your system).
cmake -DCMAKE_PREFIX_PATH=${ISL_INSTALL} -DPYTHON_EXECUTABLE=/usr/bin/python2 ${LLVM_SRC}
