Hi, I am trying to use github boost to obtain a subset of the libraries. I found that using the following subset of modules allows me to build boost_system. git submodule update --init tools/build || exit 1 git submodule update --init tools/inspect || exit 1 git submodule update --init libs/assert || exit 1 git submodule update --init libs/config || exit 1 git submodule update --init libs/core || exit 1 git submodule update --init libs/predef || exit 1 git submodule update --init libs/system || exit 1 git submodule update --init libs/utility || exit 1 The problem is that ./b2 ... install does not copy the header files. Is this a bug that I am hitting? My commands are: ./bootstrap.sh --prefix=../../boost --includedir=../../boost/include || exit 1 PATH=$CLANGBIN:$PATH \ ./b2 \ toolset=clang \ cxxflags="-std=c++11 -stdlib=libc++ -isystem/Developer/SDKs/MacOSX10.7.sdk/usr/include" \ linkflags="-stdlib=libc++" \ install threading=multi link=static Thanks, -g
