Please download the beta release candidate, give it a try, and report any problems you encounter.
I am seeing problems with b2/boost.build on Ubuntu. I have a configuration for "Clang - tip of tree", which I define thus: using clang : tot : "/Sources/LLVM/bin/bin/clang++" : <cxxflags>"-stdlib=libc++ -I /Sources/LLVM/llvm/projects/libcxx -Wno-register" <linkflags>"-stdlib=libc++" ; Works great in 1.5x through 1.71, and for 1.72.0 on Mac OS. On Ubuntu, however, it fails: $ ./b2 toolset=clang-tot/cxxstd=2a MPI auto-detection failed: unknown wrapper compiler mpic++ Please report this error to the Boost mailing list: http://www.boost.org You will need to manually configure MPI support.
