No preprocessor support in programs for GLSLES shaders?

[d000hg]

It seems from my testing that using the GLSL preprocessor_defines keyword in program scripts does not work against GLSLES shaders... no errors but the shader works as if all #define-d symbols are missing. Is this supposed to work - I guessed it'd be the same as glsl (although Cg and glsl use different script keywords).

Very useful but isn't that explicitly for GLSLESCgProgram, i.e. when Ogre automatically generates a GLSLES version of Cg shaders?

My question was for native GLSLES shaders, which I expected would support the GLSL preprocessor_defines option.

BTW - do you know if you patch made it into the 1.8.x branch?

Read the last comment in that thread.

The preprocessor should be running. Could you give an example of something not working for you?

The last comment said it might make it in...

Anyway I still think there's a slight mis-communication here: that thread is talking about using compile_arguments in a Cg shader, running on GLSLES through GLSLESCgProgram. My question is about using GLSL-style preprocessor_defines in native GLSLES shaders.

I created one GLSLES shader using a #define to render either red/green, and two separate programs - one set the #define value, the other did not. Both programs rendered the same colour. However looking at OgreGLSLESProgram, I do see code for preprocessor_defines. I'll re-test now I know the codebase is definitely supposed to support it, to double-check.
