I have a frament shader in GLSL language and when I use getUniformLocation with a variable then the function returns -1.


In fragment shader:

uniform sampler2DShadow shadowVar;


In C code:

idVariable = getUniformLocation(shader, "shadowVar");

idVariable is asigned -1.


I get this problem with ATI HD 5670 cards only.

Can anyone help me,please?
