libgcc @4.9.2_1: build failure on Leopard PPC, ld: 32-bit absolute address out of range

[mojca (Mojca Miklavec)]

Here's the error I experience while trying to compile libgcc on a PowerPC Leopard:

I've seen #44667 and #45174, but they seem to break with a different error.

Same problem here, again on Leopard (10.5.8), PowerBook G4, ppc7450. I was hoping that my computer had merely overheated! This is a serious problem as gcc46-gcc49 all need libgcc, and I am rebuilding MacPorts from scratch. Almost all of the ports I am seriously interested in require a non-native GCC to build. It's a good thing I still have _most_ of the ports from my old installation on a separate directory path, even though I can't update the gcc-4x. I hope that everything depending on the gcc-4x will update using the outdated versions.

Has anyone made any progress here?

By the way, I am using ld64-127 @127.2_0+llvm34 (with llvm-3.4 @3.4.2_1). Does anyone know if ld64-97 @97.17+llvm34 can build the current libgcc? Or a different llvm? Also--what other llvm's build on a PPC running Leopard (the only other llvm I've tried is llvm-3.3)? Any help will be greatly appreciated!

I discovered that libgcc builds on the PowerBook G4 running Leopard if it is built after ensuring that you have explicitly chosen the correct ld64; the wrong ld64 (ld64 +ld64_127) is chosen by default. For PPC users (with Leopard) experiencing this problem I suggest they try this:

sudo port install ld64-97 +llvm34
sudo port install ld64 +ld64_97

before they attempt to build libgcc. Another llvm-XX may work just as well, but that is what works for me. I guess I ought to notify the maintainer of the ld64 ports so that in the future, the correct ld64 is chosen by default.
