OpenGL and Fedora

Hi Guys

Ok i just installed Fedora Core 3 because i want to port my Windows GL app over to linux.

Anyway i got a 9800 pro and i installed all the drivers from ati for it. If i type fglrxinfo and glxinfo from the command line they both report the OpenGL vendor is ATI. So i run tuxracer at 1280x1024 and it run’s just fine so it appears the ATI driver is installed and working correctly. Ok now to my problem, i open up Kdevelop and make just a test program using SDL to create the GL window for me, this works just fine but when i run glGetString and get the renderer and version it is reporting the MESA driver ??? and obviouslly the app runs pretty slow.

Any ideas anyone??

check all the libGL.*so on your system, they may point to the MESA software ones. Or maybe it is just Kdevelop linking to the wrong versions.

Try to rename/remove the Mesa versions for GL and GLU.

ok i fixed that problem, i was using devc++ on windows so i just modified the Makefile to suit linux and now it reports the correct GL version etc BUT now i get a new problem with glext.h …here is just an example

…/…/src/glext.h:6463: error: typedef PFNGLRENDERBUFFERSTORAGEEXTPROC' is initialized (use __typeof__ instead) ../../src/glext.h:6462: error:GLsizei’ was not declared in this scope
…/…/src/glext.h:6462: error: expected primary-expression before ‘*’ token
…/…/src/glext.h:6462: error: `renderbuffers’ was not declared in this scope

i am getting this with just about everyline in glext.h …i also tried using the glext.h that ships with fedora and get the same error

ok here is my makefile, maybe i ain’t linking to something i should be???

This is not a linking problem but a compilation issue. Check for your opengl headers.

aah what a stuff up …in the headers i had #ifdef LINUX instead of linux …oops lowercase

I hope you mean your headers.

yes my headers, not fedora’s GL headers
