To do things properly it should: 1. Create OpenGL context 2. Call wglGetProcAddress("wglGetExtensionsStringARB") 3. If non NULL, call the function to get a list of WGL extensions 4. Search for "WGL_ARB_render_texture" (the provider of WGL_TEXTURE_TARGET_ARB and WGL_TEXTURE_FORMAT_ARB) 5. Act depending on its presence. Here are a couple of links which should be useful [1] <a href="https://www.opengl.org/wiki/Load_OpenGL_Functions#Windows_2">https://www.opengl.org/wiki/Load_OpenGL_Functions#Windows_2</a> [2] <a href="https://www.opengl.org/registry/specs/ARB/wgl_render_texture.txt">https://www.opengl.org/registry/specs/ARB/wgl_render_texture.txt</a> If you want to add support for the extension in mesa that'll be great. Check the Developer info [3] page for more details.
