Same code with same CMakeLists.txt works perfectly on Windows and Linux. Tested against boost 1.54 and 1.55. I'm using osx mavericks and Apple LLVM version 5.0 (clang-500.2.79) with boost 1.55 compiled by me (also tried with boost 1.54 coming with homebrew) Is there something I am missing? Thanks in advance." Bugs closed Boost 1.56.0 chrono Boost 1.54.0 Problem fixed
