Tool/software: Linux
When I use "dFdx" in my glsl program, I get a compile error:
shader err:Compile failed.
ERROR: Invalid call to function dFdx: extension OES_standard_derivatives is not enabled.
==================================
Then I add "GL_OES_standard_derivatives" to glsl program. But still can't work:
shader err:Compile failed.
ERROR: 0:0: Unexpected extension directive encountered after non-preprocessor tokens;
ERROR: 1 compilation errors. No code generated.
================================
Is "dFdx" supported on dra71x?
How to use it?
