Mysql drivers install problems

[cyberboy]

cd $QTDIR/src/plugins/sqldrivers/mysql

This would be in my case cd /usr/local/Trolltech/Qt*/src/plugins/sqldrivers/mysql/
But this directory doesn't exist, but I found the /usr/local/Trolltech/Qt*/plugins/sqldrivers/
directory and I did the sudo mkdir mysql, now I have the directory.

qmake -o Makefile "INCLUDEPATH+=/usr/local/include" "LIBS+=-L/usr/local/lib -lmysqlclient_r" mysql.pro

This would be in my case sudo qmake -o Makefile "INCLUDEPATH+=/usr/local/mysql*/include" "LIBS+=-L/usr/local/mysql*/lib -lmysqlclient_r" mysql.pro
But than I get the message : "Cannot find file: mysql.pro."

So I ran the sudo qmake -project command to get a mysql.pro file.
Afterwards I ran the sudo qmake -o Makefile.... command, with succes.
And than the make command, but I get the message "make: Nothing to be done for `first'."

So I'm really messing up something but what?

As Jacek already pointed out, you need the sources. You can't just make an empty dir and pretend they're there...

Use the Seprate source for it as JPN suggested.
And then,

qmake -o Makefile "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient_r" mysql.pro

I had compiled with this. Because the corresponding header and .so files are in my system in that location. So, Try with this. I hope it's help.
