Qt Creator for windows 64 bit



  • hi
    i want to ask that is there Qt creator available for windows 64 bit? if yes then please tell me where can i down. if not available then does anyone knows that Qt Creator has any plan to make for 64 bit windows OS?



  • I don't think so for the immediate future. At the moment, there are not even pre-compiled 64 bits binairies available. It seems there is a bug related to the 64 bits MSVC2010 compiler that affects Qt, and that is a bit of a showstopper in that area. Still: hearsay, no facts or references.



  • Interesting about the msvc 2010 bug... but msvc 2008 can also compile to 64 bit, it still strikes me as a bit odd they dont release a 64 bit binary...



  • so what should i do? as i have a laptop which supports 64 bit Windows OS espaecially windows 7. I am using Qt creator but it is creating problem for me. I keep install and uninstall to keep it working



  • What are your issues with Creator and 7 64bit?

    Because Win7 64bit is my system's main OS and i don't have any issues with Qt SDK neither with Nokia Qt SDK (this one has some installer problems, the installer is "freezing" most of the time before it ask permissions, but once installed it's working fine)



  • We do not have 64 bit Creator binaries. We may reconsider changing this as soon as precompiled Qt packages are available (which will most likely not happen within the Qt 4.7). However, you can compile Qt and Creator yourself. That said, the only ability you will be missing out with a 32 bit Creator on a 64 bit machine is debugging 64 bit MSVC-based applications.

    HTH,

    Daniel

    ok

    here is the issue.

    when i install Qt Creator on my 64bit Win 7 OS and launch it for the first time then it does not have any issue and working fine but when i close Qt creator and reopen it and then when i write code then creates problem. It does not compile and give this error

    on build issue tab

    @

    here is my code
    @
    #include <QApplication>

    #include <QLabel>

    int main(int argc, char *argv[])
    {
    QApplication app(argc, argv);
    QLabel *label = new QLabel("Hello Qt!");
    label->show();
    return app.exec();
    }

    @

    then i what i do to solve this problem is i uninstall the whole application and reinstall it. Then again if i close it then this same error appears.

    this error does not belong to only this piece of code this for every code after i closing my Qt creator and reopen.
    thanks in advance



  • We observed mingw32-make.exe crashing randomly when another MinGW installation was in the path. Can you verify that this is not the case (i.e. there is no second make.exe or mingw32-make.exe anywhere?)



  • i dont think so. Because when i install Qt creator for the first time it was creating the same problem and at that time i have never install Qt Creator before. So i think there is no such case. If it is then can please tell me how can i find out that there are another mingw32-make.exe file



  • I am pleased to announce that this is now possible with Qt 4.8.3 and MS VC++ 2012 Express. I was able to successfully compile a 64-bit build of Qt and then compile Qt Creator. For those looking to avoid all of the necessary steps (the entire process can take hours), I have a Windows installation file available here:

    https://www.box.com/s/0fa8k0nhvrtixhcbit17

    Simply download and run the installer and you will have a 64-bit build of Qt Creator on your machine. The included binaries should run on Windows Vista/7/8 (I have tested them on Windows 8).



  • Just a quick update: I have created new installers for both x86 and x64 editions of Windows. These builds are of Qt Creator 3.0.0 compiled against Qt 5.2 using Visual Studio Express 2013.

  • Hi George,
    I compiled my 64 Bit Qt Creator by myself (some problems, documentation is wrong, using private headers, changing pro files and so on)...

    But your solution is much better, hope you continue with this....

    Regards
    Peter



  • Hi, George, me again.

    You have forgotten the cdb extensions for 64 and 32 Bit. These folder must exist in $creator/lib/qtcreatorcdbext32 and $creator/lib/qtcreatorcdbext64.
    Both folders must contain qtcreatorcdbext.dll and .lib, compiled with the correct compiler (win32 or X64)..

    I would it upload here, but I cannot find any upload button....

    Regards,
    Peter
