Actually I did not solve the issue. I had setup a:
glClearColor(0.0f, 1.0f, 0.0f, 0.0f);
glClear(GL_COLOR_BUFFER_BIT);
which for the first time actually cleared something for about a second.
But strangely enough EGL was erroring and it was still intermittently
clearing the screen.
The gles2 test DirectFB provides tests functionality that has since
been deleted (even though the tests are in the same repo).
DirectFBGL/EGL calls:
eglGetDisplay
eglInitialize
eglChooseConfig
eglBindAPI(EGL_OPENGL_ES_API) which is hardwired, meaning no Desktop
OpenGL allowed (I just feel like noting that for some reason).
etc
So if you actually want to use DirectFBGL/EGL completely then I don't
think your supposed to call egl functions yourself.
Your program fails on
eglDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);
with a EGL_BAD_NATIVE_WINDOW (I may have also seen a EGL_BAD_DISPLAY
but I doubt it)
of course that could be due to the infrastructure I built around it,
but I doubt that.
I messed around for ages doing stuff, I got a DirectFB mouse cursor
appearing both in X11 and with the test app started directly from the
linux console.
Although I think it is a matter of getting the DirectFB calls setup
right (before any egl functions are called) with X11 on PC. Of course
it could be a bug in DirectFB or EGL too.
Anyway, I am going to bed.
You might want to use this for debugging:
EGLint eglerror = eglGetError();
switch(eglerror) {
case EGL_SUCCESS:
printf("eglGetError indicated SUCCESS\n");
break;
case EGL_BAD_NATIVE_WINDOW:
printf("eglGetError indicated BAD_NATIVE_WINDOW\n");
break;
case EGL_NOT_INITIALIZED:
printf("eglGetError indicated NOT_INITIALIZED\n");
break;
case EGL_CONTEXT_LOST:
printf("eglGetError indicated CONTEXT_LOST\n");
break;
case EGL_BAD_ACCESS:
printf("eglGetError indicated BAD_ACCESS\n");
break;
case EGL_BAD_ALLOC:
printf("eglGetError indicated BAD_ALLOC\n");
break;
case EGL_BAD_ATTRIBUTE:
printf("eglGetError indicated BAD_ATTRIBUTE\n");
break;
case EGL_BAD_CONTEXT:
printf("eglGetError indicated BAD_CONTEXT\n");
break;
case EGL_BAD_CONFIG:
printf("eglGetError indicated BAD_CONFIG\n");
break;
case EGL_BAD_CURRENT_SURFACE:
printf("eglGetError indicated BAD_CURRENT_SURFACE\n");
break;
case EGL_BAD_DISPLAY:
printf("eglGetError indicated BAD_DISPLAY\n");
break;
case EGL_BAD_MATCH:
printf("eglGetError indicated BAD_MATCH\n");
break;
case EGL_BAD_PARAMETER:
printf("eglGetError indicated BAD_PARAMETER\n");
break;
case EGL_BAD_NATIVE_PIXMAP:
printf("eglGetError indicated BAD_NATIVE_PIXMAP\n");
default:
printf("eglGetError returned an unknown EGL error\n");
break;
}
