So this is possibly the cause: ppc64 makes it think it is on POWER arch, while missing altogether ppc32 does not trigger any silly flags and builds fine.
comment:4 Changed 3 years ago by barracuda156
I made a patch to get rid of Power8 flag and -Wno-maybe-uninitialized and make PowerPC recognized correctly, however x265 Altivec implementation is apparently incompatible with PowerPC, the build fails on source/common/ppc/pixel_altivec.cpp.

comment:6 Changed 3 years ago by barracuda156
Turning off Altivec, I was able to build x265 as +universal:
36-109:source svacchanda$ port -v installed x265 The following ports are currently installed: x265 @3.4_0 requested_variants='' platform='darwin 9' archs='ppc' date='2022-03-08T04:22:41+0800' x265 @3.5_0+universal (active) requested_variants='+universal' platform='darwin 9' archs='ppc ppc64' date='2022-04-06T05:37:36+0800'
comment:7 Changed 2 years ago by barracuda156
So Altivec implementation uses instructions from later ISA, unsupported on Darwin. Tried adding altivec.h and using gcc12, still fails. We just have to disable Altivec on PPC.
