So the header directory isn't going to change since it's the same version of boost, but the output directories will. First you'll need to add another variant to your user-config.jam file. Like this using gcc : 6.3 : g++-6.3 ; where g++-6.3 is the compiler ext name. Then when you invoke b2 you'll name the toolset: b2 -toolset=gcc-6.3 in the bin.v2 subdirectories you'll see new subtrees for the newly compiled variants. libs/date_time/build/gcc-4.8/release/... libs/date_time/build/gcc-6.3/release/... Should one go inside each variant or should just one go at the root > directory containing the variant directories? > > Not sure I understand the question...
