    Shader issue with HD3000




      We are developing a software that uses OpenGL for 3D rendering.

      And when compiling a fragment shader we have this issue:


      Unable to create program:The fragment shader uses varying vInfo, but previous shader does not write to it.


      Indeed, my fragment shader uses that varying 'vInfo' and my vertex shader might does not write to it.


      But this works on every other graphic card brand we have.

      I have reproduced that on the latest driver (


      Any explanation of why this is not working for HD3000 graphic card ?
