llvm-3.4 fails for ppc64 on Leopard: offset in archive not a multiple of 8 (must be since member is an 64-bit object file)

Just noticed that for whatever reason it used llvm-gcc-4.2 to build, which appears very wrong for PowerPC in general. It should have used Apple gcc-4.2 instead.

llvm-3.3 fails likewise, and without it using ld64_xcode fails to build gcc7:

I don't know why but it still tries to build JIT even I disabled it. What am I missing?

ld64_xcode is not a good thing to use until something like macos 10.14 or so.

before that, macports’ tools are better.

Replying to kencu:

Thank you. I was able eventually to build llvm-3.7 as ppc64 and rebuild ld64-97 as +llvm37.

36-42:~ svacchanda$ port -v installed llvm-3.7
The following ports are currently installed:
  llvm-3.7 @3.7.1_7 (active) requested_variants='' platform='darwin 9' archs='ppc64' date='2022-03-06T09:58:43+0800'

This is arguably better than what I wanted initially, however it looks like a real pain if someone starts from scratch (gcc-4.2 won't build llvm-3.7).

[kencu (Ken)]

for ppc, I should just delete that llvm option I guess, until somebody gets llvm working properly on ppc at least.

just causes confusion.

Same issue as #64253.
