[Marshall Clow]

You need to include libc++ with clang when using c++11 library features.

See ​http://marshall.calepin.co/llvmclang-and-standard-libraries-on-mac-os-x.html for more (non-boost specific) information about this.

When I compile with

using clang : 3.0xl : /Users/viboes/clang/llvmCore-3.0-rc1.install/bin/clang++ : <cxxflags>"-std=c++0x -stdlib=libc++" <linkflags>"-std=c++0x -stdlib=libc++" ;

I'm getting the following. Is there something wrong on my installation?

[Marshall Clow]

Well, your clang crashed. That's clearly non-optimal.

On the other hand, it appears that you've got a really old clang (3.0rc1). You might try a newer one.

[Marshall Clow]

Just built this with both the current Apple released clang (part of Xcode 4.5.1) and this morning's TOT clang.

[ Using the same pattern as you in the user-config.jam ]

Both worked fine.

[Gennadiy Rozental]

I believe this is already fixed
