qtsqlite build problem

[cdarwin]

For some reason I'm getting linker errors when I try to add sqlite db to my qt project.

#include <QApplication>
#include <QtSql/QSqlDatabase>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
           db.setDatabaseName("C:/path/to/my/sqlite/file/file.sqlite");
        db.open();
        db.close();
    MainWindow w;
    w.show();
    return a.exec();
}

#include <QApplication>
#include <QtSql/QSqlDatabase>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
           db.setDatabaseName("C:/path/to/my/sqlite/file/file.sqlite");
        db.open();
        db.close();
    MainWindow w;
    w.show();
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

I also have

QT += sql

QT += sql

To copy to clipboard, switch view to plain text mode 

in my .pro file.

Any suggestions?

Problem solved. I disabled QML debugging in project menu.

Any suggestions?

Yes, the debugging option has nothing to do with this.

You must rerun qmake after you modify the PRO file... this was your likely problem.
You do not need "QtSql/" in line 2 if you have "QT += sql" in the PRO file.
