QtWebKit fails with Qt5.0.1 mingw 32bit

  • I am trying to build and run "fancybrowser" example project using Qt 5.0.1 for windows downloaded today "Qt 5.0.1 for Windows 32-bit (MinGW 4.7, 823 MB)".
    It builds fine but unfortunately it fails when launch with error:
    Starting C:\MyApps\fancybrowser-build-Desktop_Qt_5_0_1_MinGW_32bit-Release\release\fancybrowser.exe...
    The program has unexpectedly finished.
    C:\MyApps\fancybrowser-build-Desktop_Qt_5_0_1_MinGW_32bit-Release\release\fancybrowser.exe exited with code -1073741511

    Tried to create my own project. It fails the same matter as soon as I include QT+= webkitwidgets in pro file and #include <QtWebKitWidgets> in to source code cpp file.

    Question: is it something Im doing wrong or Qt5.0.1 for mingw does not support QtWebKit in general yet?

  • I have the same problem after building any example in qt5.0.1. I am posting the result from the opengl-cube example.

    If I try to use tdm-gcc or use the download from mingw32.org, I get errors during linking.

    Starting D:\Qt\5.0.1\5.0.1\mingw47_32\examples\opengl\cube-build-Desktop_MinGW_4_7_32bit-Debug\debug\cube.exe...
    The program has unexpectedly finished.
    D:\Qt\5.0.1\5.0.1\mingw47_32\examples\opengl\cube-build-Desktop_MinGW_4_7_32bit-Debug\debug\cube.exe exited with code -1073741511

    As I like to use the GNU compilers for exact portability, I am distressed I cannot take advantage of the better and more advanced API in Qt 5.


  • If You use Win XP as OS, this may be problem with reference to _vsnprintf_s function which no exist in msvcrt.dll of XP.
    If it is the case, see more at: QTBUG-29306 (MinGW: Qt 5.0.1 problem with _vsnprintf_s on Win XP.)

  • It is not just mingw...
    I would say it is more of a WebKit or QtWebKit wrapper problem
    experiencing similar "glitches" here with MSVC2010 build
    e.g. try these (on certain sites)
    framecapture.exe and browser.exe crash while it seems to be working in fancybrowser...

    I'm also experiencing random crashes deep inside WebKit

    I guess we'll have to wait for 5.1 or 5.x for thing to stabilize

  • I have exactly the same problem, as soon as I try to instanciate an object that has to do with the QtWebKit (like QWebView, QWebPage...) I have the same notifications. The same when I try to compile examples that use QtWebKit.

  • try to upgrade compiler Qt5.1.0
