[maemo-developers] Problem running ogles2 program on Nokia N900

[From: Jonny Karlsson]

I have successfully compiled an OpenGL ES 2.0 program on scratchbox for 
the FREMANTILE_ARMEL plattform. However, when running the program on Nokia 
N900 the compilation of the vertex and fragment shaders fails. This is the 
error code:

------------------------------------------------
Failed to compile fragment shader: Compile failed.
ERROR: 0:1: 'varying' : syntax error; parse error
ERROR: 1 compilation errors. No code generated.


Failed to compile fragment shader: Compile failed.
ERROR: 0:1: 'attribute' : syntax error; parse error
ERROR: 1 compilation errors. No code generated.


Failed to link program: Link Error: Vertex shader is missing.
Link Error: Fragment shader is missing.
--------------------------------------------------

This is my vertex shader:

 	const char* pszVertShader = "\

 		highp attribute vec4 myVertex;\
 		lowp attribute vec4 fargKod;\
 		mediump attribute vec2 myUV;\
 		highp uniform mat4 yRotMatris;\
 		highp uniform mat4 xRotMatris;\
 		highp uniform mat4 frustMatris;\
 		lowp varying vec4 outColor;\
 		mediump varying vec2 myTextCoord;\
 		void main(void)\
 		{\
 			outColor = fargKod;\
 			myTextCoord = myUV;\
 			gl_Position = myVertex * yRotMatris * xRotMatris;\

 		}";

and this is my fragment shader:

 	const char* pszFragShader = "\
 		uniform sampler2D sampler2d;\
 		mediump varying vec2 myTextCoord;\
 		void main (void)\
 		{\
 			gl_FragColor = texture2D(sampler2d,myTextCoord);\
 		}";


These shader compile successfully and works fine when I run the same 
OGLES2 program in the simulation environment.

Does anyone have a clue what could be wrong? Is there perhaps something 
that need to be installed on the Nokia N900 to add shader compilation 
support to it???
