Remove Boost libstdc++ dependency with clang++/libc++?

Question

The answer to this question How to compile/link Boost with clang++/libc++? states to build Boost with clang++ and libc++, the following should do:

./b2 clean
./b2 toolset=clang cxxflags="-stdlib=libc++" linkflags="-stdlib=libc++"

I tested the above tip on a Scientific Linux 6.4 x86_64 host and it works "mostly" building the full Boost 1_53_0 distribution, with clang++ 3.3sv and libc++ 3.3svn. I said mostly, as I really like to remove all libstdc++ dependency.

Nevertheless, the following:

• libboost_graph
• libboost_locale
• libboost_regex

still shows libstdc++ dependencies (the ldd output makes it quite obvious). I would like to know a good way to remove such and would appreciate any hint.

Answer 1

I found out how to do it. Thanks to @Howard Hinnant for his mentioning of libc++abi. After RTFM http://libcxx.llvm.org/, it's trivial to build the entire boost libraries free of any libstdc++ dependencies. Yes, all I had to do is to RTFM!
