koga/units.lisp fails to find clang and clang++ #1353

Open Ambrevar opened 2 years ago

Ambrevar commented 2 years ago

On some distros like Guix clang may not be in the llvm-bindir. Then Koga fails to set cc and cxx.

Easy fix:

(setf cxx (configure-program "cxx"
                                 (or cxx
                                     (merge-pathnames #P"clang++" llvm-bindir)
                                     "clang++")
                                 :required t))

Similar for cc.

This isn't really a bug, but a configuration variation. If you need to specifiy the path to clang you can do it on the koga command line via ./koga --cxx=path-to-cxx --cc=path-to-cc or create a config.sexp with (:cc "bla" :cxx "baz")

Fair enough, but Koga could fallback to the compiler basename by default so that it's found in the PATH.

Well, maybe but we will need to do some version verification at a minimum. Our clang binary & library detection is a bit weak right now. Its on my todo list to improve it,
