Yes, that seems to be quite the same to my workaround. Its just that this is a workaround that is difficult to get working in some contexts: I want to use emacs-irony-mode through guix which is not really useable because it won't autocomplete any std::* stuff. If you take all packages that might want to use libclang and other features of clang it might be a better solution to find a proper fix for this problem. Also both workarounds need a user profile that is cluttered with all include files. I had a quick look into clangs source code how C_INCLUDE_DIRS is implemented. It should be more or less easy to add the same option for C++ (even C_INCLUDE_DIRS seems to be tinkered in to me). I just wanted to file a bug about this because fixing this is not trivial and I am not sure whether I will find the time right away to fix it. Fixing it would also have the benefit that I could send the patch to the LLVM mailing list and we might see the change upstream in the next LLVM version. Tim.
