This is a case where I compiled boost with a different version of g++ (or perhaps without c++0x support??) resulting in binary incompatibility when the BOOST_SCOPED_ENUM is used in the header of a compiled library.
This seems like a bad API choice as it requires all programs that use boost::filesystem::copy_file to use the same version of G++ with the same compile options. In this case, the library should (in theory) implement both the scoped enum and unscoped enum implementation so that I can mix and match C++03 code with C++0x code without having two different versions of boost::filesystem.
You cannot safely mix and match C++03 and C++11 code with GCC no matter what libraries you use. The standard library itself breaks binary compatibility between the two versions. Boost builds on the standard library. So no change in Filesystem is going to rescue binary compatibility for you. Sebastian
