I installed the development enviroment into my dev-Cpp directory but (in windows xp professional) ,Dev-C++ (from bloodshed software) still says it' can't find the files (I pretty much know that it's because of the slashes "/" in the filename), KDevelop and gcc all do the same thing on Linux (mandrake 9.1). The thing about linux is that GTK 2.0 and gtkmm already come installed. (by the way I'm totally new to linux but I'd like to use GTK on both platforms. Can you help me with my problem? I have printed out your complete gtk 2.0 tutorial and the faq (thanks to the HP 4600 Laser printer they left unguarded @ school?) and still my problem != solved; I hope you can help me with this because it's becoming a pain in the neck. __________________________________ Do you Yahoo!?
