Some time ago, someone asked this list about gm2 on PPC Mac. The following query and response should help. Basically, first build GCC-10 and then use it to build GCC-13.

I have not tried it yet because my G5 is currently unavailable but I shall try it.

I have a ~20 year old 32 bit Power PC macintosh system that still runs.

Yup .. me too - my oldest oldest is a 500MHz power mac AGP (runs darwin8 and takes 3 days to bootstrap the compiler and a week to test it)..

.. but mostly I work on a Quad G5.

Can someone tell me the most recent version of GCC that still supports
this platform?

GCC supports powerpc-darwin9 (and actually powerpc using Rosetta on darwin10) up to and including current trunk (GCC-14). The only constraint is the compiler used to bootstrap the build.

Iff you want to build GCC with the last released xcode (3.1.4) for Darwin9 [MacOSX 10.5] then you will need to stick with GCC10.x as the last version (newer GCC now needs C++11 to bootstrap, which is not supported by xcode 3.1.4).

However, once you have a suitable bootstrap compiler [GCC 5 or newer] you can use that to build any current version of GCC.

I publish branches with some “go faster stripes” for MacOSX / Darwin here:
(but for powerpc darwin, the upstream branches should also be fine).
