Fixed bug 3169 - GLES2_CreateRenderer does not check SDL_GL_GetAttribute result, causing use of uninitialized data Yann Dirson When attempting to force use of opengles2 renderer with: int wanted_renderer = -1; for (int i = 0; i < numrenderers; i++) { SDL_RendererInfo renderer_info; if (SDL_GetRenderDriverInfo(i, &renderer_info) != 0) { SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't get renderer driver info: %s\n", SDL_GetError()); quit(2); } std::cerr << "Renderer " << i << " '" << renderer_info.name << "': flags=0x" << std::hex << renderer_info.flags << std::dec << ", " << renderer_info.num_texture_formats << " texture formats, max=" << renderer_info.max_texture_width << "x" << renderer_info.max_texture_height << "\n"; if (!strcmp(renderer_info.name, "opengles2")) { std::cerr << " selecting!\n"; wanted_renderer = i; } } renderer = SDL_CreateRenderer(window, wanted_renderer, 0); ... on banana pi or raspberry pi I get an error like the following (the actual context profile value varies, being used uninitialized) ERROR: Couldn't create renderer: Unknown OpenGL context profile 900 With this patch I get the following, which should help more pointing to a real problem: ERROR: Couldn't create renderer: Failed getting OpenGL glGetString entry point I pushed a patch (based on master branch of unofficial git mirror): https://github.com/O-Computers/SDL/commit/550389c89f4e73a0a5294f95b9f6e6c18ba48509 I'll be opening a different bug for the underlying issue.
