Creating MySQL driver returns error

[Momergil]

Hello!

Some time ago I did a research in order to discover how to create the MySQL driver for Qt and after various failed helps I managed to find this website, whoose process to create such driver runs sucessfully:

After doing this process succesfully in two different machine, for the first time I'm incapable of creating the driver pointing always the error that mysql.h is missing:

Could somebody please point out what is the problem? Where can I find mysql.h? Could this be due to the MySQL installation folder is in F: and Qt installation is in C:?

Thanks,

Edit: at the end of the web page it is stated: "You can’t use MySQL 64 Bit (at the moment) to compile the plugin.". I'm not sure, but it is really probable that I'm using a 64 bit MySQL... Does somebody know if this restriction is still valid?
