Platform: Windows XP Pro Boost version: 1.38 1.39 (BoostPro binary release)

try { boost::filesystem::create_directory ("C:\Program Files\hello123"); } catch (const boost::filesystem::basic_filesystem_error& ) { std::cerr << "Directory creation failed" << std::endl; }

The above code crashes if user doesn't have root permission. I assume some exception is being thrown as catch (...) catches whatevers being thrown. The documentation says "Throws: basic_filesystem_error<Path> if Effects fails for any reason other than because the directory already exists." The requested directory "C:\Program Files\hello123" doesn't exist, so I should have caught a boost::filesystem::basic_filesystem_error. Is this a known issue or am I the only one seeing this?

basic_filesystem_error<Path> is not the same as basic_filesystem_error as Path will be a boost::filesystem::path type. If in doubt, catch (std::exception &e) and inspect the type of e in the debugger. Regards -- Craig

If you want to know what exception in being thrown, you could try std::cerr << boost::current_exception_diagnostic_information() in the catch(...), after including . Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
