Could not open database or xml outside qtcreator installation platform



  • I am running on windows 7 + qtcreator 2.0.1, and i am managing an sqlite database: here is the code:

    @
    //OPENING AND SETTING UP THE DATABASE
    QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE",myconn);
    db.setDatabaseName(QCoreApplication::applicationDirPath()+QDir::separator()+"Application.db");
    db.open() //Returnin false! :(
    @

    The xml code has the same behaviour ..
    This code works good into win7, so i compiled the app and moved it ( exe+dll ) to xp. I started the application and the db could not be found from the point of view of db.setdatabasename. I installed Qtcreator on xp, and then everything works. It seems that there must be another library hidden somewhere that has xml and database support What do i have to add to my project in order to support sqlite and xml out of the box?
    Those are the file i have near my exe:
    Application.db
    libgcc_s_dw2-1.dll
    mingwm10.dll
    QtCore4.dll
    QtCored4.dll
    QtGui4.dll
    QtGuid4.dll
    QtNetwork4.dll
    QtNetworkd4.dll
    QtSql4.dll
    QtSqld4.dll
    QtXml4.dll
    QtXmld4.dll
    SpeedyInstaller2.exe
    test.xml

    Thanks :)

    EDIT: moved to install and deployment, gerolf

    Make sure to also ship the Qt plugins.

    There are tools to watch which files a application is trying to open available for windows. Those are really great to find out what is missing in a installation. My guess is that you do not have the sqlite plugin in your installation.



  • You have a distribution problem, which was already often discussed here on DevNet. And it is also described in the docs.
