Tried both llvm-11 and llvm-14, seeing different issues.

These are steps on debian bullseye
git clone --recursive https://github.com/google/autofdo.git
cd autofdo
mkdir build
cd build
# Note: "-DCMAKE_INSTALL_PREFIX=." must be used, because there is a bug in the basil cmakelist.
cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=. -DLLVM_PATH=/lib/llvm-14/ ../
ninja
ninja test

Hi Markuze, we recently merged PR #155 to make the tool buildable against the newest llvm. So would you be able to build a newest llvm and pass the path to "-DLLVM_PATH="?

Hope it would help.

Nah, straight up been coming back about every month or so see if this crap is working yet. This software has never, worked, 99% won't compile. Absolute garbage.

I was able to successfully build the autofdo tool(branch 2022.09.merge) using LLVM 15, and Propeller is working well for optimizing MySQL with the create_llvm_prof tool.

I also faced with this problem. Have you solved it?Could your solution
