    You have MySql installed, right?

    Yes, up until the reinstall I had been using Qt and MySQL together, successfully, as described in post #9. Connecting to databases, running queries, etc. I also am able to access MySQL databases through independent tools (MySQL Administrator and MySQL Query Browser). I can rebuild from the .tar file as in #9 but that takes hours and it seems ridiculous to have to go through that just to get the MySQL drivers.

    Is mysql.h present in /usr/local/include?

    No I didn't, I had it in /usr/include/mysql. When I put it in /usr/local/include and re-ran the qmake/make commands, I got

    How about passing /usr/local/include/mysql instead of /usr/local/include into configure? The problems you are having are strictly related to files and compilers and not to Qt and MySql.
