SDL2 with OpenGL ? weird results, what's wrong? (stevo5800)

Thanks for taking a look.
The screenshot come from OS X, so you need to replace the iOS project file
with the OS X project file that is located in the*"desktop OS X stuff"
The middle and the last pictures use SDL2 instead of the original SDL –
all on OS X. The last image uses a pre-alpha quality non-standard OpenGL
library that they advertise as compatible with GLES.
The black screen on iOS problem is a separate issue that I addressed in
another SO question
(it explains that I use a GLES compatibility library that is supposed to
take care of glBegin/glEnd stuff)----------------------------------------------------------------------

The middle and last picture where taken from what platform? *I download
the code from a link on the stackexchange page and all I get is a black
screen. Middle image seems like it’s missing a lot and the last image
sees that it’s only missing textures. After looking at the code I
realize that you are calling calls that are not compatible with OpenGL
ES. You are using glBegin(…); glEnd(); witch are not available on
mobile devices. You will need to use VBO’s or Vertex Arrays for all
drawing to the screen.
