Deploying a Qt application in Windows 7



  • Hi!

    This is the situation:

    I set up a Qt development environment in my Windows 7 to port a Qt application I made for Linux. The compilation process goes pretty clean, but in the moment I try to run the binary, I got this message from the GDB debugger:
    @Program received signal SIGSEGV, Segmentation fault.
    0x69dea1c6 in QObject::disconnect (sender=0x22fe48,
    signal=0xc769269 "iconSizeChanged(QSize)", receiver=0x1000001,
    method=0xc7692b1 "_q_updateIconSize(QSize)") at kernel/qobject.cpp:2906
    2906 kernel/qobject.cpp: No such file or directory.
    in kernel/qobject.cpp
    Current language: auto; currently c++@
    Note: I copied all the Qt libraries required by my application (QtCore.dll, QtGui.dll, etc) in the directory where the binary file (.exe) is created.

    Is there another library required? What am I missing? Thanks for any hint :)



  • Did you try run it from QtCreator?



  • Yes, that was my frist try indeed and all I got was this from the QtCreator log:
    @Starting C:\tupi\sources\tupi-build-Desktop-Debug\src\bin\tupi.mobile.exe...
    The program has unexpectedly finished.
    C:\tupi\sources\tupi-build-Desktop-Debug\src\bin\tupi.mobile.exe exited with code -1073741819@
    Looking for better information about the issue, I opened a system console and ran the .exe by myself, then I got several messages of missing .dll files. I put all the files required in the same location but the program never started anyway.

    Next step? I ran the application from gdb and then I got the message I shared in the first post. Suggestions? :(



  • This is a trouble in your code. Some part of code works in linux but not in windows. Try find it in debug mode.
