    @vladinko0 It belongs in your main.cpp:

    int main(int argc, char *argv[])
    {
        // Options on Windows; set before instantiating QApplication
        // QCoreApplication::setAttribute( Qt::AA_UseOpenGLES ); // use DirectX via ANGLE
        
        QApplication app( argc, argv );

      @vladinko0 I know. Can't you use Qt Quick Application?

          Hmm. If you have an ANGLE capable Qt version and set the Qt::AA_UseOpenGLES attribute and it still doesn't work then I don't know. Sorry :-(

            I had exactly the same issue with Qt 5.4.1 MinGW 32-bit

            @Wieland solution to force ANGLE is the good one, but it doesn't work. In fact I'm not sure this version support it. If you look into the \Qt5.4.1\5.4\mingw491_32\bin directory you will not find libEGL.dll, libGLESv2.dll and d3dcompiler_47.dll. I used to work with ANGLE but with Microsoft Visual Studio 2013 compilator, and these libraries are provided in the Qt distribution : "Qt 5.4.1 for Windows 32-bit (VS 2013, 705 MB)"

            @Wieland do you have MinGW or VS2013 compilator ?

                Thanks Wieland, that's explains why forcing ANGLE in your case is working and not for vladinko0

                @vladinko0, I suggest you to install Visual Studio 2013 (Express is free), and install Qt 5.4.1 for VS2013. Force Qt::AA_UseOpenGLES like Wieland says. Because your graphic chipset is old, perhaps you will need to set the environment variable QT_ANGLE_PLATFORM to d3d9 (if it doesn't support DirectX 11).

                  @boumath I tried VS2013 with Qt 5.5 .0 but no success. :(

                    According to Intel documentation the Q35 Express chipset only supports OpenGL 1.3. That's waaay to low for Qt.

                    You can run the ANGLE (or dynamic) version of Qt (OpenGL layer on top of DirectX). It's the package without "OpenGL" in the name mentioned by @Wieland. This still won't let you run some of the OpenGL examples. It's high time for an upgrade ;)

                    Hi,

                    If you are still on the same machine the message from Chris:

                    Is still valid

                      In fact I changed my machine. Graphic card is now Intel(R) Graphic Media Accelerator 3150. Result for Qt 5.4.1 mingw32 is the same.

                      I forgot to mention, that with msvs2013 andQt 5.5 .0 the error is little bit different:
                      Starting C:\Users\Vladimir\Documents\build-untitled11-Desktop_Qt_5_5_0_MSVC2013_32bit-Debug\debug\untitled11.exe...
                      QML debugging is enabled. Only use this in a safe environment.
                      class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): Could not initialize EGL display: error 0x3001

                      class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): When using ANGLE, check if d3dcompiler_4x.dll is available
                      C:\Users\Vladimir\Documents\build-untitled11-Desktop_Qt_5_5_0_MSVC2013_32bit-Debug\debug\untitled11.exe exited with code 0

                      At the end project is launched.

                        GMA 3150 only supports OpenGL 1.4. That's still waaaaay in the woods. You're still gonna need to use ANGLE.

                        Did you try what the message says? "When using ANGLE, check if d3dcompiler_4x.dll is available"
                        This dll should be placed next to your executable.

                          Yes, I tried to put that file in to C:\Users\Vladimir\Documents\build-untitled11-Desktop_Qt_5_5_0_MSVC2013_32bit-Debug\debug
                          but no luck.
