Windows deploy failure



  • I write a small chat app by QT, My Qt version is 5.6.2 MinGw 32bit, my system is windows7 sp1 64bit. At first, my program run well from Qt Creator , it behaves normally and achieves my goal, so I decide to deploy it. I use windeployqt to deploy it, my deploy folder looks like thisalt text
    After I click client.exe, it shows the loginpage like thisalt text
    After I type the username, password and click login button, somethins strange happens
    alt text
    the client.exe stopped working, I open the dump file by visual studio , it shows the error code 0xC0000005 The thread tries to read and write a virtual address and it does not have the appropriate access to the address
    the xml file shows

    Maybe the problem is Qt5Core.dll, but the client.exe run fine and behave well in the release folder, so I am very confused. Then I copy the deploy folder to another computer which doesn't install Qt. Thel client.exe shows the loginpage too, but stop working when it need to show the mainwindowalt text

    So how can I figure my problem , since it runs well in Qt Creator both in debug version and release version
    Thanks in advance,
    xiaxun



  • I use Dependency Walker to test the client.exe, here is the resultalt text
    it shows the Link Checksum and Real Checksum of QT5CORE.DLL are different, is it the reason?



  • Hi, the checksums are irrelevant (Windows does not care) so I think Qt5Core.dll is not the problem.
    But the list in your Dependency Walker shows some Windows system .DLLs that are 64-bit and that your Qt files are 32-bit, that could be the reason for the crash.



  • @hskoglund @SGaist
    how can I force my appliction to link my 32bit windows libary, since my system is windows 64 bit, here is my configure page
    alt text
    alt text
    I searched the google and found some solution, do I neet to add CFLAGS += -m32 in my pro file.
    I also search this pagelink textSince my Dependency Walker picture above is 64bit version, now I also try the 32bit Dependency Walker in my 64bit system, it output with nothing wrong, does it make any difference?
    Thanks in advance

    Hi,

    Something's not clear here, how many different version of Qt do you have on your system ?

    What parameters did you pass to windeployqt ?



  • @SGaist
    Hi, SGaist, thanks for your answer.I only install qt-opensource-windows-x86-mingw492-5.6.2alt text
    I didn't pass any paramenters to windeployqt

    The bit depth of dependency walker doesn't matter. You can use 32 or 64 bit for your application.

    What I do in this situation is put it together manually. Create a directory, put your exe in it. Run your exe and it will pop up with a message box saying something like "your app needs xxx.dll to run". Copy that dll into your directory and run again. It will show the next one. Keep doing this until your application starts.

    Oh and in order to do this you have to make sure you don't have your mingw dlls or your Qt dlls in your PATH or they will auto detect and run. If you don't want to remove them from the path what you can do is use another system (preferably a virtual machine or one without any development stuff installed) and copy your exe there, then supporting dlls as prompted.

    This is the long way to do this and something that should automatically be done by windeployqt. But in cases where I've had issues, this is a tried and true approach that I use. If you can make it run on a fresh windows VM without and development stuff installed, it will definitely run on an end user's PC. :)



  • @ambershark
    I tried as you said, I remove the Qt from the PATH, the program works well in my computer now, but fails on another computer , the exception point to Qt5Core.dll ,Since it is a release version, I don't know how to debug it.


  • Lifetime Qt Champion

    What Qt modules are you using in this application ?


  • Moderators

    @Masonsu My guess is you don't have the platform plugins.

    Most dlls it will tell you but for plugins (especially platform) it just crashes a lot.

    In your main directory create directories plugins/platforms and then put the appropriate platform libs in there. I don't remember what they are for windows off the top of my head. They will be in /your/qt/path/plugins/platforms. If you have issues copy everything from that dir into your new one.

    Lastly if you still have issues, you can use a qt.conf file in your application directory to tell it where your plugins are.. create a text file qt.conf that looks like:

    [Paths]
    Plugins = plugins

  • Moderators

    @Masonsu I highly doubt it's your code. I've seen this many times before. We'll get it figured out. :)

    Ok so if you could show me a directory listing of your application's directory and all sub dirs. Using a command prompt you could do:

    cd /your/path
    dir /s /a > dirlist.txt
    

    Then post that dirlist.txt file here. Also show me the contents of your qt.conf file if you made one.

    Also you shouldn't need the mingw includepath or libs path. If those need to be set in the .pro file that is already a problem, in my opinion, for your build. Especially since they are hardcoded to only work on your system. But that isn't what's causing the issue, that is just for your information later on to make your build better. It should work on any system without having to change the pro file or having things in certain directories to mirror yours.

    @Masonsu Sorry I meant the directory for your application that you are distributing. The one that goes on the machine that isn't working.

    I need to see if you have the right dlls/file names/dir structure, etc.



  • @ambershark @SGaist @hskoglund
    I am sorry for that, it is nothing wrong with deployment but with my code.
    I check my code again and found something wrong. I use illegal index of a QList after I login successfully, it crashes the deployment version, but it doesn't crash when I run it from QtCreator, here is the code

    UseInfo::UseInfo(QWidget *parent) :
        QWidget(parent),
        ui(new Ui::UseInfo),
        sqldb(new DbManager()),
        username(Socket::username)
    {
        ui->setupUi(this);
    
        QStringList qlist;
        for (int i = 1960; i < 2016; ++i)
            qlist.append(QString::number(i));
        ui->yearComboBox->addItems(qlist);
        qlist.clear();
        for (int i = 1; i < 13; ++i)
            qlist.append(QString::number(i));
        ui->monthComboBox->addItems(qlist);
        qlist.clear();
        for (int i = 1; i < 32; ++i)
            qlist.append(QString::number(i));
        ui->dayComboBox->addItems(qlist);
    
        sqldb->insertName(username);
        QList<QString> list = sqldb->readInfo(username);
        avatar = list[0];
        gender = list[1];
        year = list[2];
        month = list[3];
        day = list[4];
        job = list[5];
        phone = list[6];
        email = list[7];
        address = list[8];
        hobby = list[9];
    
        setIcon(avatar);
    
        setUseinfo();
    }
    

    so before assign the value to my class member variable, I need to check if the list is empty
    thanks for all your reply


  • Lifetime Qt Champion

    Are you sure that readInfo returns 10 values ?

    By the way, why return a QStringList rather than an object that represent these info ?



  • @SGaist said in QT Windows deploy failure:

    Are you sure that readInfo returns 10 values ?
    By the way, why return a QStringList rather than an object that represent these info ?

    NO, so I said that I need to check that if list is empty, after I added if (!list.empty()), everything runs well
    To the second quesion, maybe my design is not good, I didn't think too much, sorry for my poor English


  • Moderators

    @Masonsu Good to hear this is fixed. And your english is great. :)
