Hi,
I have been trying to create opengl es 3.0 context using the latest 1.4.1 es 3 emulator. The example I am using is cube example of es 2 emulator. I have added the header "EGL/eglext.h" to use EGL_RENDERABLE_TYPE as EGL_OPENGL_ES3_BIT, and include GLES3/gl3.h as well. Also has set context attribute as EGL_CONTEXT_CLIENT_VERSION , 3.
EGL_NONE
};
The code is compiling correctly but giving error as :
No EGL configurations were returned.
Tried to set not RGB size and RGB size as 565. But same error.
I am using windows 7 with visual studio 2012. Same code is working fine for OPENGL ES 2.0 context using same OPENGLES 3.0 emulator. Do we need to set anything else?
Thanks.
Hi Jacek,
Yes, I had Mali offline compiler and es 2.0 emulator installed (which I installed to get the cube example).
So, now I uninstalled the offline compiler and all the emulators. Updated the Nvidia driver again to the latest version. And installed the latest OPENGL ES 3 (1.4.1) emulator.(Everything installed new).
Thus, I am able to create the OPENGL ES 3.0 context with some changes. I had to set the EGL_SURFACE_TYPE to EGL_WINDOW_BIT.
Below if the output of compilation and run:

After copying 'openglessl' directory from C:\Program Files (x86)\ARM\Mali Developer Tools\Mali OpenGL ES Emulator 1.4.1 to example\cube, I was finally able to run the code
Thanks for making making me uninstall and install everything, it worked. Thanks again.
harsha,
Happy to help!
One more thing - I'm a bit worried that you had to copy openglessl folder to example\cube.
I would expect Mali OpenGL ES 3.0 Emulator to set its environmental variables during installation time and then find needed libraries in the installation folder during execution time.
Could you please reopen the command prompt (so it can pick up new environmental variables) and let me know if the cube example can be successfully run without openglessl in example\cube?
Thanks,
Jacek
I deleted openglessl folder from example/cube and reopened the developers command prompt, but even though it is giving the same error:
In Create Window
Creating ogles3 context
Tried executing cube.exe through system32 command prompt too but same error.
Copying back the openglessl directory executes the binary.
Hi harsha,
Mali OpenGL ES 3.0 Emulator tries to find openglessl directory in the installation folder using the registry key (seems to be failing in your environment), and if that fails then tries to find it in the current directory (works in your environment).
In your case I would expect that the registry contains following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ARM Ltd\Mali OpenGL ES Emulator 1.4.1
with the default value of (assuming that the product was installed in the default location):
C:\Program Files (x86)\ARM\Mali Developer Tools\Mali OpenGL ES Emulator 1.4.1
Could please confirm that?
Cheers,
