SDL with OpenGL support.
 

Hello,

I'm trying to compile caprice32, a cpc emulator. It seems to make use of the OpenGL extensions for libSDL. I do not seem to see any of these available in the nokia/maemo distribution archive, as follows:

Is there a way to use the opengl extensions in libsdl on n900?


Thanks,

Re: SDL with OpenGL support.
 

i think n900 doesn't support opengl, but opengl es version only

Re: SDL with OpenGL support.
 

Any pointer what to do in this case? I am trying to compile DCSS tiles and get the same error...

Re: SDL with OpenGL support.
 

There is no OpenGL support. There is only OpenGL ES (1.1/2.0) support. GLES 1.1 headers are found from GLES/gl.h. Depending how the original OpenGL program was made there can be quite a bit of porting work to make it work with OpenGL ES.

If you'd like to use OpenGL ES easily with sdl, you can use libsdl-gles1.2 to create gles rendering context.
