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.xmlThanks :)
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.
