I have a WinXP SP3 machine running. I got a fresh qt 5.5 out of the online installer. I'm trying to lauch some simple test application with QML 2.x but I get the following error while starting it : 

"Failed to create OpenGL context for format QSurfaceFormat bla-bla-bla...
Make sure that libEGL.dll, libGLESv2.dll and d3dcompiler_*.dll are available".

Well, I have d3dcompiler_43.dll at C:\WINDOWS\system32 ( after installing DirectX Software Development Kit ).

I also have libEGL.dll and libGLESv2.dll at C:\Qt\5.5\mingw492_32\bin.

So what is the problem I'm facing?

BR, Dmitry

  • try updating the graphic card drivers – Miki Jul 09 '15 at 14:18
  • as far as I understand libEGL.dll and libGLESv2.dll are intended to get rid of graphic driver dependencies...am I right? – Dmitry Jul 09 '15 at 14:28
  • not an expert, but they should rely on the graphic card drivers – Miki Jul 09 '15 at 14:33
  • winXP can be used with DirectX 9c latest...could be a problem here? What is the minimum version for qt 5.5 required? – Dmitry Jul 09 '15 at 14:36

  • sorry, but it doesn't give any explanation for the problem I have – Dmitry Jul 09 '15 at 14:43
  • I can't give you further detail. Sorry about that. Probably others have a solution.. wait for them! – Miki Jul 09 '15 at 14:47
  • no problem, such kind of issues are rather tricky always. it's so sad that there is no backward compatibility for qt...to much efford for deployment – Dmitry Jul 09 '15 at 14:52

  • yes, I saw it, I have OpenGL 1.1 ... so is there any way to start qml 2.x with qt 5.5 on my PC? – Dmitry Jul 09 '15 at 15:12
  • Does your graphics card not support OpenGL 2 or above? – cmannett85 Jul 10 '15 at 06:02
  • Well, of course I can install OpenGL 2.x on my PC. But what if I need to deploy my application on some PC which is not under my control...I should take care about all these details...seems not to be a convinient solution. I'd prefer to give an *.exe and *.dll-s... – Dmitry Jul 10 '15 at 11:44
