Can't say for sure, never use VS myself, but on the basis of the error message I'd speculate that you have not linked against the fltk lib in your link command. You'd likely need to show us more details, like what commands the IDE (or your command line, in this case, I guess) actually executed and so forth. For what it's worth, I genuinely find it easier to use mingw to build Windows code, than using the MS VS tools and IDE's. See here (dated but still valid...) for more info: http://www.fltk.org/articles.php?L598 As regards the wider question of somebody helping, I'd suggest that if you are serious about programming, then the best person to help you is you... You need to really, properly, understand why the build is failing, what the error means, and what to do about it. Sure, we can tell you how to fix it, but that is not the same thing. Note that the question you are asking is not a fltk question, it is about using the tools, so you have to get those fundamentals in place so that you can start the journey... _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
