Well it built fine and MAME+Gui is working again but now..
I just set all my paths up in M+GUI, and told it to Audit all my roms and its giving me this error:
"While parsing /Volumes/Storage/MAME/ini/mame.ini:
Illegal integer value for numprocessors: "auto"; reverting to auto"
Is this possibly related to the -j3 flag?? I was about to go rebuild it again just using plain old make but figured I would ask first..
Gotta love the G5 compared to my G4.. The initial build of the game list took a couple of minutes if even that. On my old dual 1.6 G4 I would get up and go run errands while waiting for it to finish that first process haha.
