I’ve successfully used PVRFrame libraries on MinGW32 as GLES emulator. After switching to MinGW64 to get full c++11 standard support II’ve downloaded and integrated the latest PVRFrame GLES2 x64 libraries to my MinGW64 environment. I could compile my GLES2 sources without any failure. But on runtime my application crashes if I try to crate a VBO:

[Fri May 17 11:09:15 2013]: EGL window created.
[Fri May 17 11:09:15 2013]: EGL windows surface created.
[Fri May 17 11:09:15 2013]: EGL render context created.
I simple call:
GLuint vertexbuffer;
glGenBuffers (1, &vertexbuffer);
As you can see, the OpenGLES2 environment is set up correctly. I could check the GLES2 extensions and successfully initialize and create the required EGL objects (Display, Window, RenderContext). But if I call a standard OpenGL Extensions, this call fails (same also on GLSL shader object creation). My GLES2 sources are correctly, I use the same sources on Android ADT platform, without any issue.
Is it possible to use this great PVR emulator on MinGW64?
Best regards,
