Hello, I have build Boost 1.55 on OSX 10.8.5 and I have written a short example to get the temporary path of my system. So I run std::cout << temp_directory_path() << std::endl, and it results "B?@?e/test/libboost_hA?@??%UP^?" I have build Boost with bjam myself and otool results the correct linked file. How can I solved the error? Thanks a lot Phil
