Found a cmake issue and fixed almost all of it, down to 1 missing reference:


/ede/smonsees/yocto/test/beignet-Release_v1.3/backend/src/llvm/llvm_to_gen.cpp: In function ‘bool gbe::llvmToGen(gbe::ir::Unit&, const void*, int, bool, int, std::__cxx11::string&)’:

I can see that libclang is being included...so, not sure why when linking an executable these references are missing...

It should be linking in libclang , I will validate...

Note performing 'nm' on libclang appear to show the majority present...

Question: if I needed to include a library, what/how would I modify a recipe under Yocto to be sure to include/link in the library ?

Thanks,
Steve

I am building meta-clang (sumo based 6.0.1), with cmake (3.8.2), all

Are the following routines accessible/supported under meta-clang ?

are you linking this library with libclang ? secondly, also check that its not emitting bunch of libraries which needs to then individually linked



thanks,

Steve
