Error when building pluto dev : configuring PET

[abdksm]

Hi, After building LLVM from source I am trying now to build pluto (the dev version). I am not sure which path should I provide in this command (./configure [--enable-debug] [--with-clang-prefix=<clang headers/libs location>]) since I am getting the following error when configuring PET: checking for main in -lLLVM-14.0.6... no checking for clang/Basic/SourceLocation.h... no configure: error: clang header file not found checking for pet/Makefile... no configure: error: configure in pet/ failed For now the provided path is: /usr/llvm-project/build
