When I am setting MULTI SAMPLE BUFFERS and SAMPLES value in attributes its getting failed… I am using Open gl version 1.3 and EGL 1.5
With EGL for a window system layer, are you really using OpenGL or OpenGL ES?
Are you sure you’re running OpenGL 1.3? That’s ancient.
What GPU and GPU GL driver version do you have installed? What hardware is this?
Also, let’s see some code for how you are trying to enable multisampling support. For EGL surfaces, you need to set EGL_SAMPLE_BUFFERS to 1 and EGL_SAMPLES to the desired number of samples per pixel in the EGLconfig attributes you pass in.
