Date: Sun, 30 Apr 2006 14:20:05 +1000 From: Rob Subject: [SDL] SDL pre-release OpenGL fails on the zipped pre-release source accessible from http://www.libsdl.org/svn.php. Appears to be following lines in sdl_wing.c (lines 341-345): wglext = (const char *)this->glGetString(GL_EXTENSIONS); if ( !SDL_strstr(wglext, "WGL_EXT_swap_control") ) { this->gl_data->wglSwapIntervalEXT = NULL; this->gl_data->wglGetSwapIntervalEXT = NULL; } glGetString is a null pointer, as are other gl function pointers, so call fails. Never looked at sdl source before, so no further than that as yet.
