Summary: iPod touch 2nd gen crash due missing opengles2
Product: SDL Reporter: IvanG <ivang>
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: HG 2.0   
Hardware: iPhone/iPod touch   
OS: iOS (All)   

Description IvanG 2011-10-09 16:14:12 UTC 
Crash happens on iPodTouch 2nd generation (os version 4.2.1)

when SDL_SetVideoMode() is called (only flag set was SDL_HWSURFACE) crash happens in:

SDL_GLContext UIKit_GL_CreateContext(_THIS, SDL_Window * window) in SDL_uikitopengles.m gets called trying to create "opengles2" renderer.

    /* construct our view, passing in SDL's OpenGL configuration data */
    view = [[SDL_uikitopenglview alloc] initWithFrame: [uiwindow bounds] \
                                    retainBacking: _this->gl_config.retained_backing \
                                    rBits: _this->gl_config.red_size \
                                    gBits: _this->gl_config.green_size \
                                    bBits: _this->gl_config.blue_size \
                                    aBits: _this->gl_config.alpha_size \
                                    depthBits: _this->gl_config.depth_size \
                                    majorVersion: _this->gl_config.major_version];
// above call returns NULL
    data->view = view;
// crash happens on next line because view is NULL:
    view->viewcontroller = data->viewcontroller;
    if (view->viewcontroller != nil) {
        [view->viewcontroller setView:view];
        [view->viewcontroller retain];
    }


As workaround I'm using
SDL_SetHint(SDL_HINT_FRAMEBUFFER_ACCELERATION, "opengles");
prior to SDL_SetVideoMode() call
