GLXW is an OpenGL loader that dynamically links with OpenGL at runtime. It supports OpenGL core profile, OpenGL ES 2, OpenGL ES 3, WGL, GLX and EGL.

GLXW is a Python script that downloads OpenGL header files from official locations, parses them and generates the loader library headers and sources.

1. Run the glxw_gen.py script to download GL headers, parse them and generate loader. See --help for command line options.

   $ python glxw_gen.py
   

2. Include glxw.c to your project sources and add glxw to your include path. Link with OpenGL libraries and/or EGL libraries as applicable. On Linux and other Unix platforms that use dlopen(), link with -ldl. Alternatively, CMake can be used to generate and build GLXW.

3. In your project, #include <GLXW/glxw.h> and call glxwInit() when an OpenGL context is active. You do not have to include standard OpenGL headers, they are included from glxw.h.

   #include <GLXW/glxw.h>
   
   if(glxwInit() != 0)
       handle_error();
   

4. If you use CMake and intend to rebuild a lot or use GLXW as a CMake subproject, copy downloaded headers to glxw/include to avoid re-downloading after every "make clean".

   $ cp -R build/include/{GL,GLES2,GLES3,EGL,KHR} include/
