Could you please attach a full main.log? Also on which macOS version does this occurr?

[barracuda156]

Sure, please

I don’t think this is anything arch-related, tbh.

It seems configure is selecting preferred compiler Xcode-gcc-4.2 for me, and this is not supporting the symbol aliasing properly.

macports apple-gcc-4.2 works for me as far as i386 x86_64 +universal on 10.5.8 Intel (I don't have a newer 4 arch [ppc ppc64 i386 x86_64] compiler working yet).

$ sudo port -n upgrade --force  libmd +universal configure.compiler=apple-gcc-4.2 'configure.universal_archs=x86_64 i386'

$ port -v installed libmd
libmd @1.1.0_0 requested_variants='' platform='darwin 9' archs='i386' date='2025-10-30T15:54:01+1300'
libmd @1.1.0_0+universal (active) requested_variants='+universal' platform='darwin 9' archs='i386 x86_64' date='2025-10-30T16:19:08+1300'

local-link.h strong_alias() does not seem to be working with the Xcode compiler.
The assembly code under #if defined(__APPLE__) probably needs separate code blocks added for ppc & ppc64 I guess.
