Date: Wed, 4 Mar 2009 15:38:22 +0200 From: "Mike Gorchak" Subject: Re: About QNX support in SDL 1.3 Here is another batch of patches. 1) Makefile.in - added SDL_opengles.h header as header to install. 2) configure.in - Added special define to detect Common Lite OpenGL ES library in case if Common library is not installed. Added check for clock_gettime in libc (in QNX it is in libc). 3) SDL_config.h.in - Added SDL_VIDEO_RENDER_OPENGL_ES and SDL_VIDEO_OPENGL_ES declarations for configure script autodetection. 4) SDL_opengles.h - Added GL_API definition if it is not defined. Added extension GL_OES_draw_texture because OpenGL ES Renderer uses it without declaration. Added GL_OES_vertex_buffer_object extension, which is supported under QNX OpenGL ES. Added GL_OES_single_precision extension. 5) To the test directory I've added building OpenGL ES test applications through the autotools suite. Was support for iPhone IDE building only.
