include path of hipcc

[VinInn]

I'm confused about the actual origin of the c++ headers for hipcc (I assumed to be our gcc distribution.
Instead it seems to come from a local installation

I'm in

[innocent@patatrack03 binary64]$ echo $CMSSW_BASE/

If I compile something with it

so it seems to take gcc header files from

indeed (added a little #warning in the local file)

@fwyzard FYI

[smuzaffar]

@VinInn , we pass --gcc-toolchain=$(COMPILER_PATH) to hipcc (as hipcc uses llvm as backend compiler) (https://github.com/cms-sw/cmsdist/blob/IB/CMSSW_14_2_X/master/scram-tools.file/tools/rocm/rocm.xml#L18 ) when used within cmssw. I think llvm 13 and earlier versions were able to pick gcc headers from COMPILER_PATH env variable but with llvm 14 and above we had to explicitly set --gcc-toolchain ( #8201 ) . I had opened an issue about this llvm/llvm-project#56343 .
