Clean up the EGL resources; After obtaining a display, you initialize it, set the preferred configuration, and create a surface with a back buffer you can draw into. eglInitialize initializes the EGL display connection obtained with eglGetDisplay. These constructs include a display, a configuration, a window surface, and a context. * * @return {@link #SURFACE_STATE_ERROR} if the correct EGL context cannot be made current, * {@link #SURFACE_STATE_UPDATED} if the EGL context was changed or * {@link #SURFACE_STATE_SUCCESS} if the EGL context was the correct one */ int checkCurrent. The current version of SGX DDK provides OpenGLES2.

They're currently using an EGLStreams implementation (instead of GBM like everyone else) which none of the compositors/toolkits support at the moment (since everyone uses GBM). Certain window systems require a special function to be called to initialize threading support. Once you have finished getting started you could add a new project or learn about pygame by reading the docs. You'll use the same EGL display and EGL configuration to create the EGL surface as you used to set the properties on your native window. 251 =====OUTPUT INFO===== Now, I'm written over openbox session because I cannot start GDM :'( Futhermore.

" ; const char *egl_bad_access_string = "EGL cannot access a requested resource (for example a context is bound in another thread). These are the top rated real world C++ (Cpp) examples of initEglTraceLevel extracted from open source projects. Wiki from www.
