I met problem when building llvm2c
It seems that some function is miss in newer llvm version

I've just tested the build with final release of LLVM 13 on Fedora and everything compiled without any issues for me. What distro are you using?

[Moriarty002]

I don't know what happen to my environment , my system has both llvm-13 and llvm-14 , may be I need to set the path to llvm ?

You can select the desired LLVM version by passing -DLLVM_DIR="$(llvm-config-13 --cmakedir)" to CMake assuming that LLVM 13's llvm-config is in your PATH (it is called llvm-config-13 on Debian and Ubuntu). Otherwise, you need to specify a full path to the corresponding llvm-config binary.
