Yup - this one really had me tearing my hair out, but the solution was... For some reason that I don't remember, a while ago I put /usr/lib/{firefox,thunderbird} into my ld.so.conf. This is not generally a good idea :) Oddly enough, it didn't seem to adversly affect anything ... until recently. I made no connection between this and UAE segfaulting, I mean after all, what has UAE got to do with Mozilla, right? Well a couple of minutes ago I tried to launch Galleon - "relocation error ... libnecko.so ... undefined symbols." Eeek! Then Epiphany - "relocation error ... libnecko.so ... undefined symbols.", then mozilla-bin - "relocation error ... libnecko.so ... undefined symbols." I saw a pattern forming ... :) So I checked the binaries with ldd, and sure enough they were looking in /usr/lib/{firefox,thunderbird} for libraries. Not good. So I removed the offending lines from /etc/ld.so.conf and ... success !!! On a hunch, and with fingers crossed, I launched UAE, not really believing that there would be any change to the pevious segfault problem. Unbelievable ... it works !!! And it didn't break Firefox or Thunderbird either :) Er ... weird! YAMtastic. Regards, -- K.
