All you need is an installed version of LLVM or a previous +build. To configure Polly to use a pre-built LLVM, set the +<code>-DCMAKE_PREFIX_PATH</code> option: + +<pre>cmake -DCMAKE_PREFIX_PATH=${LLVM_PREFIX}/lib/cmake/llvm</pre> + +To run unittests, however, you need to have the LLVM source directory around. +Polly will use the <code>llvm-config</code> of the LLVM you're building against +to guess the location of the source directory. You may override autodetected +location by setting the <code>-DLLVM_SOURCE_ROOT</code> option. <h3> Troubleshooting</h3> |
