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();
}
