Help please, trouble running OpenGL ES 3.0 Programming Guide code

Sam Gupta

Greetings:
I installed the Mali simulator successfully (cube spins). Then I tried to run the OpenGL ES 3.0 Programming Guide sample code following instructions there. The steps I took and the problem/error is below. Any help appreciated.
Thanks in advance,
Sam

Open cmake gui.
Set source code “opengles3-book-master” and build folder.
Configure -> error -> set “libEGL.lib” and “libGLESv2.lib”.
Configure + generate (now no error).
Open build folder and open ES3_Book.sln with MSVS.
Make Hello_Triangle startup project.
Build (all 21 succeed, 0 fail).
UP TO HERE IT’S FINE. PROBLEM NEXT STEP
Debug: a window (where the triangle should be drawn) pops up for a second and then dies. Error:

It fails on line 213:

if (!Init(esContext)) { return GL_FALSE}

At that moment esContext.egNativeDisplay is NULL

    Hi samg,

    I looks like Mali Emulator is working. What you seem to have is a problem in OpenGL ES 3.0 Programming Guide samples. We don't support that.

    I did however look quickly into the code and it seems like esContext.eglNativeDisplay is not defined for win32. I am assuming you are running these samples on Windows. If would add

    esContext->eglNativeDisplay = EGL_DEFAULT_DISPLAY;

    Before line 213 in Hello_Triangle.c and see if that works.

    HTH,
