GLSL doesn't compile for some reason..

So don’t ask me for entire code, there is no need. The problem is here.

If I type this code into GLSL, it works. Doesn’t give me non-compiled shader error.


	int index = int(gl_Normal.x);
	
	float r = radians(rotations[1000].z);

If I type this code however, shader doesn’t compile. What is wrong?


	int index = int(gl_Normal.x);
	
	float r = radians(rotations[index].z);

This won’t compile also.


	int index = int(0);
	
	float r = radians(rotations[index].z);
