I am using the OpenGLES2 SDK , which I downloaded from your website.

I want to load binary vertex and fragment shaders, precompiled using PVRUniScoEditor tool. I got an error in glShaderBinary function
  

Error: GL\_INVALID\_ENUM&nbsp; // format error
  

&nbsp;
  

I am using PowerVR SDK in PC Emulation mode using Desktop Nvidia Graphic Processor. 
  

Is there a way to load binary shaders using above hardware specification?
  

&nbsp;
  

Thanks

No, our OpenGL ES 2.0 PC Emulation does not support binary shaders. Unless you are targeting a single, closed SGX platform you should always provide source shaders as fallback.
