Hi dngr!

Could you tell us a little bit more about your environment? What version of Windows are you running? Is it 32-bit or 64-bit?

That's fine for now thanks! We haven't tested the emulator on a 64-bit Windows 7 platform, but we'll try it out and get back to you ASAP.

Hello,

This not helps...

The "cube.exe" example works fine if you are member of "Administrators" group,
or you have the administrator privileges.

And this error occurs, if you are simple user without administrator privileges.
Looks like the line:

sEGLContext = EGL_CHECK(eglCreateContext(sEGLDisplay, aEGLConfigs[0], EGL_NO_CONTEXT, aEGLContextAttributes));

requires the Administrator to work. This is not good...

How to solve this problem? Because of security reasons I do not work with
administrator privileges!

Thank you.

P.S. System Win XP, x86.

Hello,I got the same problem, making this change to cube.c works for me (at line 210):

#ifdef _WIN32 hDisplay = EGL_DEFAULT_DISPLAY; // GetDC(NULL); #else hDisplay = XOpenDisplay(NULL); if (!hDisplay) { printf("Could not open display\n"); exit(-1); } #endif

dngr, could you please try this?

Hi Lorenzo,

I get the same problem; my environment is a 32-bit Windows XP laptop with an Nvidia Quadro FX 360M graphics card, using driver version 6.14.11.7575. I'm building using Eclipse and a Cygwin-gcc toolchain. The change that you suggested results in a 'Could not open display' message from line 217.

Ta,
Mark

Hi Medge,
line 217 should not be executed with the _WIN32 definition. Are you sure you have moved the #endif at line 220, after the if(!hDisplay) entire block?
Unless you want to use cygwin with a X11 server on Windows, in this case the problem could be different.
