I'm trying to install boost on OS X with c++11 and libc++. I'm using homebrew (boost formular with the --build-from-source argument) and have tried various options with adding stuff like * toolset=clang * cxxflags="-stdlib=libc++ -std=c++11" * cxxflags="-stdlib=libc++" * linkflags="-stdlib=libc++ -std=c++11" * linkflags="-stdlib=libc++" as arguments to bjam, but it all fails. Now... The "toolset" part doesn't do anything to make it fail though, its the cxx- and linkflags part that does. This is what I get when it fails clang-darwin.archive bin.v2/libs/exception/build/clang-darwin-4.2.1/release/link- static/threading-multi/libboost_exception-mt.a common.copy /usr/local/Cellar/boost/1.50.0/lib/libboost_exception-mt.a clang-darwin.compile.c++ bin.v2/libs/wave/build/clang-darwin-4.2.1/release/link- static/threading-multi/cpplexer/re2clex/cpp_re.o clang-darwin.archive bin.v2/libs/wave/build/clang-darwin-4.2.1/release/link-static/threading-multi/libboost_wave-mt.a common.copy /usr/local/Cellar/boost/1.50.0/lib/libboost_wave-mt.a ...failed updating 2 targets... ...skipped 4 targets... ...updated 10592 targets...
