Description Bernard Cafarelli gentoo-dev 2010-10-20 11:56:29 UTC 
From bug #327575:
I tried to build Boost.Thread with clang and it looks like clang can't find
#include <cxxabi.h>
in file ($BOOST_ROOT)/boost/exception/detail/type_info.hpp:18

After checking on my system, this file is located in
/usr/lib/gcc/i686-pc-linux-gnu/4.4.4/include

The directory is not present in clang executable.

As the header is included C-style (with .h), clang may filter it out (the USE flag only sets C++ headers path)

Yes, just to be precise, I built "clang" with the system-cxx-headers USE flag. It might not be obvious reading my previous post.
Comment 2 Bernard Cafarelli gentoo-dev 2010-10-21 08:13:47 UTC 
Without system-cxx-headers, you would not have gone that far ;)

I found the problem, clang also has a --with-c-include-dirs option, which needs a GCC correct path. clang-2.8-r2 now sets it, and emerge with clang now goes to the end

Thanks for the report!
