Compiling with Clang using Libc++ undefined references

Question

The first couple are too long to reference. I get this error when I try to compile clang++ -stdlib=libc++ ../main.cc ... with clang and libc++ from the SVN.

Answer 1

Here's what works for me with the Ubuntu Vivid packages for clang and libc++:

clang++ -std=c++11 -stdlib=libc++ <object files> -lc++abi -lsupc++

It is important that the object files come before the -l flags, e.g. when you use exceptions. Obviously, this still will not link if you use libraries compiled against libstdc++ and use any STL types in those interfaces.

Answer 2

This seems like you are using exception handling, but it isn't enabled in the compiler. Try passing -fexceptions to the commandline.

Answer 3

I believe libc++ doesn't support all exception functions yet. See the status page:

http://libcxxabi.llvm.org/spec.html

You could probably link against gnu's libstdc++
