I’m using Qt5.0.2 for Windows 32-bit (VS 2010, OpenGL) on a Win7 64bit.
My app requires the network module in addition to standard libs. Here are the dlls deployed with the app:
1) Qt5Network.dll, Qt5Core.dll, Qt5Gui.dll, Qt5Widgets.dll
2) icudt49.dll, icuin49.dll,icuuc49
3) msvcp100.dll, msvcr100.dll
4) platforms\qminimal.dll, platforms\qwindows.dll
The app runs fine on Win 7 and up. However, on some Windows XP machines it crashes on start, in which case Windows asks to submit report with qt5gui.dll as the problematic file. I have no control over those machines so I cannot provide more details, other then those from windows crash report for the release version.
As far as I understand, if one needs to use QtQuick2 he can either use Qt5-ANGLE or use Qt5-OpenGL and hopes that end users will update the drivers manually to support OpenGL v2. However, if QtQuick2 is not used, does Qt5 still require some version of OpenGL? Are Qt5Gui.dll and Qt5Widgets.dll based on OpenGL? I assume that on some Windows XP machines there are no OpenGL v1 graphical drivers – which can be the cause of the crash.
Finally, if QtQuick2 is not used, isn’t better to use ANGLE to better target Windows XP?
Any input is greatly appreciated!
