Your clang and your llvm don't match, they're often version locked and you need to make sure both of them are the same-ish revision.

Sorry in advance for the limited details.
I have a build of a recent (Monday) llvm/clang which I have installed in the expected way in my environment but I am getting failures like this; In file included from /lib/clang/stable/include/x86intrin.h:29: In file included from /lib/clang/stable/include/immintrin.h:118: _/lib/clang/stable/include/avx512cdintrin.h:37:20: error: use of undeclared identifier 'builtinia32vpconflictdi512' _return (_m512i) _builtinia32vpconflictdi512 ((_v8di) A); ^ _/lib/clang/stable/include/avx512cdintrin.h:59:20: error: use of undeclared identifier 'builtinia32vpconflictsi512' _return (_m512i) _builtinia32vpconflictsi512 ((_v16si) A); ^ Any suggestions on what might be messed up in the build/installation? (In other contexts I would delete all build directories and restart but in this workflow I know everything started from clean checkouts) Thanks for any help david
