Struggling to build the activeqt expamples shipeed with QT sd 5.3

  • Hi Guys,
    I installed qt 5.3 -- I wanted to write some activeqt program , but failed to build so. i go to Examples\Qt-5.3\activeqt\comapp. From QT creator when i open the project and build it - i see the following errors:
    E:/Qt53/Tools/mingw482_32/bin/mingw32-make -f Makefile.Release

    Could you please give me any pointer?


  • Have you solve your problem? I also have the same problem!

  • Got the same problem on Windows 7 with Qt 5.2 and 5.4. The only difference is that in Qt 5.2 idc would not timeout and will wait forever.
    I tried to dig in and found some clues:

    Idc tool tries to run newly built project executable with command line argument "-dumpidl". Because of "QT += axserver" in project file, g++ should link program against qaxserver.lib instead of qtmain.lib. Argument "-dumpidl" then should be parsed in WinMain in qaxservermain.cpp, WinMain should call DumpIDL and return immediately.

    Promblem is, for some reason WinMain is never called. Instead, program execution starts in main() in qaxmain.cpp. This function starts COM-server, constructs QApplication and enters event loop. It doesn't even call user's implementation of qMain (WinMain does). Idc tool thus times out and after that there is no output .tdl file because DumpIDL was not executed.
    Currently I am stuck at this point. g++ receives "-Wl,-subsystem,windows" flag, so entry point for application should be WinMain(), not main(). I would appreciate any help.
