> /tmp/cc4BY3Jt.s:38: Error: Unrecognized opcode: `lvsl' => Altivec Hmm.. Altivec itself should work on 10.2 (flac compiles fine...) Could you try this patch? http://workaround.ch/pub/rsync/au/liboil.diff (patch -p 0 < liboil.diff) ..oh.. and modify the 'test_altivec' void inside liboil/liboilcpu.c (remove the asm stuff) After this two changes, liboil seems to compile on 10.2. No idea if it still does what it's supposed to do.. :-)
