[cfe-dev] Compiling boost with -std=c++0x (and -stdlib=libc++)

[Ryuta Suzuki]

Hi,

I have trouble compiling the following trivial boost program

#include <boost/thread/thread.hpp>

int main()
{
  return 0;
}

Actually, clang and libc++ work perfectly fine:

[ryuta at oroppas]$ clang++ -stdlib=libc++ ./boost_thread.cpp

However, once we deploy -std=c++0x flag,

[ryuta at oroppas]$ clang++ -std=c++0x -stdlib=libc++ ./boost_thread.cpp

I'm not sure if this could be a boost / clang / libc++ bug.
Any comment will be greatly appreciated.

Thanks,

Ryuta
