Of course it has it but it is OpenGL 1.5 not OpenGL ES 1.5.

Before OpenGLES version 2.0 (shader pipeline), you only have OpenGLES
1.1 and OpenGLES 1.0. See https://en.wikipedia.org/wiki/OpenGL
Thanks for your response.
I’m seeing the method glBlendEquationOES in Apple’s headers so I assume this is
available in the OpenGLES framework included with iOS (8.0 at least). Not sure
how to load the extension though...
I’ll probably just deal with the default blending equation until I can
im
Is it available in any version before 2.0 do you know? I don’t know much about
OpenGL but there is a 1.5 version also which maybe has it.
I found this page also which suggests it exists on some 1.x version.

Indeed, glBlendEquation is simply not available in OpenGLES 1.1.
See the specs: https://www.khronos.org/op
Thanks I didn’t know any loading had to be called.
Does this work on OpenGLES 1.x do you know? I’m going to try this on iOS also.

I’m using OpenGLES 1.1 because it was easier to learn but I don’t see
glBlendEquation being included in the GLES11 unit. Maybe it didn’t exist until
OpenGLES 2.0?

Just tested on iOS and I get that error. I think on iOS it loads from the
OpenGLES.framework and therefor this is failing. Also that load function wasn’t
available but it failed upon including the GLExt unit.
An unhandled exception occurred at $0001000CDEF7:
