Hi,
After installing the new NVIDIA ForceWare 84.21 driver, I've gotten the following error message while compiling GLSL shaders:
(0): error C9999: symbol "@TMP1" already in tableThe unclear thing is that the error didn't occur before installing the driver and I've changed nothing in my shader code after installing it, hence I don't recognize this is whether the driver's bug or my shader's bug.
Any ideas?
Edited:
I just validated my shader code using 3Dlabs' GLSL Syntax Validator and found that the cause of the error is a mat4-to-mat3 conversion as follows (where u_RotationMatrix is a mat4 uniform variable):
mat3 rotation = mat3(u_RotationMatrix);Now, the mat4-to-mat3 conversion is not included in the official GLSL specification? It is quite inconvenient to be unable to use the matrix conversion.
