Today I got the following error message in the mediatomb log:
> ERROR: You disabled both, sqlite3 and mysql but one
> database driver must be active!
I had sqlite enabled in config.xml, mysql deactivated. What I did not know at first: gentoo did not install the sqlite driver, only the mysql one.
The error message could be more specific, e.g. "The enabled database driver "sqlite" is not compiled in." or such.
