I m busy ATM and can't answer you immediately, but i ll test it tomorrow at work on a debian. World not running might not be linked to compilation troubles or kernel issues. World will crash on certain database errors. Try running it without the &, from the /eqemu/server directory, ie :
cd /eqemu/server
./world
What shows on the console will certainly help ya to figure what's wrong... If you can't fix it by urself, please ask for support into the linux support forum please, we d'like to keep tutorial forums for ... tutorials
I ll revise the part concerning mysql-config, if you don't have it, you can still compile the Freebsd way, thank you for leading my attention to that point, i ll add it to the guide.
