[SOLVED]Clang and Library Files

I just installed Clang and it doesn't have the c++ libraries founded yet.

These are the directions I have to fix it but I have no idea where it's located.

If you intend to work on Clang C++ support, you may need to tell it how to find your C++ standard library headers. If Clang cannot find your system libstdc++ headers, please follow these instructions:
'gcc -v -x c++ /dev/null -fsyntax-only' to get the path.
Look for the comment "FIXME: temporary hack: hard-coded paths" in clang/lib/Frontend/InitHeaderSearch.cpp and change the lines below to include that path.

Any help would be appreciated.

There are likely candidates such as /usr/lib/ but really why not just ask pacman

pacman -Ql clang | grep InitHeaderSearch.cpp

Thanks for replying Trilby; I don't get a return back when I enter that command.

Oops, sorry, I typed to quickly.

As it is referring to a cpp source file you won't likely have that file. You may have to patch and recompile clang or llvm yourself, unless someone has already put such a patch in the AUR.

As I don't use clang I should probably leave this to those who do.

Hmnn, looks like I'll have to wait for a Clang expert to comment on this. Meanwhile I'll just do a little more reading to see if I can solve it. Thanks.

You say you're trying to use clang for c++... perhaps you meant to use clang++? We have none of the story here -- what's the actual error you're getting and what did you run to get it?

I ran clang name.cpp.

So as I said, you're using clang which is a C compiler. You want clang++, which is the C++ compiler.

Thanks! Dumb mistake.
