Had to google it up myself: http://www.linuxbase.org/spec/refspecs/ links to http://www.linuxbase.org/spec/refspecs/elf/elfspec_ppc.pdf, don't know if that's the one though. > > BTW, this isn't a PPC specific problem, there's a reason why Debian > > policy mandates that shared libraries consist entirely of -fPIC code: > > they break otherwise on pretty much anything but i386. ... and prevents prelinking everywhere, I should add.

Yes, it's a bit unfortunate that the problem only manifests itself at runtime (and not 100% deterministically... although prelinking 'helps' somewhat there), but AFAIK Dan intends to change that in the toolchain at some point. -- Earthling Michel Dänzer \ Debian (powerpc), XFree86 and DRI developer Software libre enthusiast \ http://svcs.affero.net/rm.php?r=daenzer
