Hi there,  
  
  
  
  
  
I’m using the GLES2 windows PC emulation. After compiling the samples they all fail to run as they cannot find a valid GLES 2 EGL\_RENDERABLE\_TYPE.  
  
  
  
  
  
On further investigation I dumped out a list of all the configs available (using eglGetConfigs). The results are:  
  
  
  
  
  
EGL\_RGB\_SIZE(S) 8:8:8 - EGL\_BUFFER\_SIZE 32, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 8:8:8 - EGL\_BUFFER\_SIZE 32, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 8:8:8 - EGL\_BUFFER\_SIZE 32, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 4:4:4 - EGL\_BUFFER\_SIZE 16, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 4:4:4 - EGL\_BUFFER\_SIZE 16, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 4:4:4 - EGL\_BUFFER\_SIZE 16, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 5:6:5 - EGL\_BUFFER\_SIZE 16, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 5:6:5 - EGL\_BUFFER\_SIZE 16, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
EGL\_RGB\_SIZE(S) 5:6:5 - EGL\_BUFFER\_SIZE 16, EGL\_DEPTH\_SIZE 24, EGL\_RENDERABLE\_TYPE : 1  
  
  
  
  
  
EGL\_RENDERABLE\_TYPE : 1 equates to EGL\_OPENGL\_ES\_BIT rather than EGL\_OPENGL\_ES2\_BIT  
  
  
  
  
  
My graphics card is a very capable Radeon X1950 with very latest drivers. Is the only solution to this to buy a new graphics card?  
  
  
  
  
  
Many thanks,

I've switched from ATI to NVidia 3 years ago when I started using the PowerVR SDKs.  
Can you run the binaries provided? Guess not!

Hi there. Nope, cannot run the binaries provided, they fail in the same place.

Hi,

1. Are you using Native window or through some VMware or any other virtual box?

2. Can you run Normal OpenGL (desktop) applications?
