11.1. What is needed to have OpenGL support in Wine
Basically, if you have a Linux OpenGL ABI compliant libGL ( http://oss.sgi.com/projects/ogl-sample/ABI/) installed on your computer, you should have everything that is needed.
To be more clear, I will detail one step after another what the configure script checks.
If, after Wine compiles, OpenGL support is not compiled in, you can always check config.log to see which of the following points failed.
11.1.1. Header files
The needed header files to build OpenGL support in Wine are :
- gl.h:
the definition of all OpenGL core functions, types and enumerants
- glx.h:
how OpenGL integrates in the X Window environment
- glext.h:
the list of all registered OpenGL extensions
The latter file (glext.h) is, as of now, not necessary to build Wine. But as this file can be easily obtained from SGI ( http://oss.sgi.com/projects/ogl-sample/ABI/glext.h), and that all OpenGL should provide one, I decided to keep it here.
11.1.2. OpenGL library itself
To check for the presence of 'libGL' on the system, the
script checks if it defines the
glXCreateContext function.
11.1.3. glXGetProcAddressARB function
The core of Wine's OpenGL implementation (at least for all
extensions) is the glXGetProcAddressARB
function. Your OpenGL library needs to have this function
defined for Wine to be able to support OpenGL.
