QT opengl shader error with K20 GPU

Using 5.5qt. I encountered this error when plotting 3d opengl using nividia GPU
Vertex shader for simpleShaderProg (MainVertexShader & PositionOnlyVertexShader) failed to compile

do I need install some API extension or driver etc? seem like I’m missing something
