Problems with MySQL on Ubuntu

[neoclaw]

When I try to compile the mysql plugin for Qt4 using "sudo make", I get this error: "make: Nothing to be done for 'first'". Any ideas on what I can do to fix this?

well, then properly the building is already complete.

hmm.. that may be the reason
But after I re-compiled the whole Qt package, and compiled this code:

#include <QCoreApplication>
#include <QtSql>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    qDebug() << QSqlDatabase::drivers();
 
    return a.exec();
}

#include <QCoreApplication>
#include <QtSql>

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

    qDebug() << QSqlDatabase::drivers();

    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

all output I get is: "( )", so I would assume no sql database drivers are installed...

I thought the plugin was the problem, but it didn't help.

How do you recompile Qt package?
