opengl issues compiling on mac osx?

i'm compiling a client on mac osx and have been getting an error from lots of the files in the opengl folder in the graphics folder in minorGems. i'm using osx 10.6.9 (snow leapord) with the gcc, and have the opengl and sdl 2.0 libraries installed properly (in system/library/frameworks). here are some of the errors

first the glInclude file is messed up and can't find gl.h or glu.h. this might be why the other stuff after it isn't working
then a lot of stuff is "not declared in this scope"

i think the problem is that it can't find gl.h or glu.h even though i have opengl installed and the other stuff is because of that first problem.
can anybody help?

Re: opengl issues compiling on mac osx?

I'm pretty sure TCD doesn't use SDL 2, just plain ole SDL.  Try installing that and see if it works. (I don't think there's a Mac dev version, but if you install just the normal version, it should work).

Re: opengl issues compiling on mac osx?

Yeah, I think the OpenGL headers have moved in later versions of OSX.  I'm building on 10.5, which I think had them in an OpenGL/ folder (this is not standard, usually they are in a gl/ folder).

So, I created  minorGems/graphics/openGL/glInclude.h  to deal with the mess of finding the OpenGL headers.

You'll probably have to edit that file in the $ifdef __mac__ section to tell it where to look for those headers.  Maybe just remove the OpenGL/ part... maybe <gl.h> and <glu.h> will work?

i got the old sdl too and it still won't work. i think the problem is opengl.

the problem i was running into was that the files were located in the folder /opengl.framework/, not just /opengl/. i changed glinclude to look for the headers at <openGL.framework/gl.h> and the previous errors are gone.

i also replaced my opengl framework with the developer one from the osx 10.6 sdk. now it works fine. thanks jason!
