I was able to build libc++, but when I try to use -stdlib=libc++ I get the following error:
/usr/bin/ld: /tmp/test-347fdf.o: undefined reference to symbol '__cxa_free_exception@@CXXABI_1.3' /usr/lib/x86_64-linux-gnu/libstdc++.so.6: error adding symbols: DSO missing from command line clang-3.5: error: linker command failed with exit code 1 (use -v to see invocation) Any ideas what is going wrong here?
