I have a notebook which has ATI graphic card and the detail spec is as follows,

  • 8.763.1.1000
  • ATI Technologies
  • AMD Radeon HD 6550M

My driver seems to be up to date. But it is not changed since 8/28/2010.


I use uniform block to implement multiple light shading. But when I use uniform block the shader link error occurred.

  • "Fragment shader(s) failed to link, vertex shader(s) failed to link. unexpected error. unexpected error."


Without using uniform block, it is hard to handle multiple light information.


There is similar case like me in the follows link.

GLSL uniform struct init in shader error!
