How to integrate QT with OpenGl

ManiRon

Hi I have been trying to create my first QtQuick Application QML and while trying to run the application i am not able to run and it throws an error saying that

static QWindowsEGLStaticContext* QWindowsEGLStaticContext::create(QWindowsOpenGLTester::Renderers): Could not initialize EGL display: error 0x3001

static QWindowsEGLStaticContext* QWindowsEGLStaticContext::create(QWindowsOpenGLTester::Renderers): When using ANGLE, check if d3dcompiler_4x.dll is available

This is most likely caused by not having the necessary graphics drivers installed.

Install a driver providing OpenGL 2.0 or higher, or, if this is not possible, make sure the ANGLE Open GL ES 2.0 emulation libraries (libEGL.dll, libGLESv2.dll and d3dcompiler_*.dll) are available in the application executable's directory or in a location listed in PATH.

Any reason to use such an old version?

What OS?
Did you try to update graphics driver?

ManiRon

@jsulm My laptop is old and i donno whether it supports new version of QT, Now i solved the issue by installing openGL in my laptop, but i am facing an issue while opening the designer form of QML , The Qt creator crashes , I am using QT5.5

You could simply try as you can install as many Qt versions as you like.

ManiRon

@jsulm which version i could try out with ? i donno which one to install

jsulm

@ManiRon Well, the latest stable (5.15.2)?

ManiRon

@jsulm can you provide me the download link for that

jsulm

@ManiRon It's not hard to find it.

@jsulm if suppose my laptop doesnt have any graphic card in it then whether the QML designer form will work ?

jsulm

@ManiRon Do you mean you have integrated graphics unit (in the CPU)?
It doesn't matter as long as you have working OpenGL graphics driver, so try to update them if you have issues.

ManiRon

@jsulm is there a way to find that i have installed the correct openGL

@ManiRon Check whether there is a newer version of the graphics driver for your laptop/graphics card (integrated graphics).
