I'm not exactly sure where to post this, but the people here at the C::B forums have been exceptionally helpful with everything I've had, so that's why I'm asking it here, so I apologise if this isn't the place. Maybe someone here has encountered the same issue that I am.
I've been attempting to compile the libraries for FLTK and Fox for the last couple of days in Code::Blocks/MinGW (which neither of them have any documentation on building with), and both of them have encountered relatively similar issues. For both, I opened up the .dsw for MSVC out of simplicities sake, which I believe works in C::B. Either way, I started it up, and it said it couldn't find local header files. I defined in C::B the folders where the header files were, and it continued compiling happily, until it reaches an odd point where it encounters a variable that had not been defined (both times, in FLTK and in Fox). For FLTK, the variable 'rint' was not defined, and in Fox, the variable big_gif was the same situation. I have a feeling it doesn't really have anything to do with the variables themselves, and instead it's something I'm not doing before starting the compile.
