Qsqlite linker error

[darwwin]

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();
}@

@QT += sql@

is set

Any suggestions?

just to make sure:

clean your project

rerun qmake

build project again

Problem solved. I disabled QML debugging in project menu.
