Description
On 10.6.8 Rosetta I get the following errors, though the build still succeeds (and apparently binaries work, otherwise I could not get anywhere further from MoarVM).

Also gcc12 does not recognize -Wno-logical-op-parentheses flag, though does not err out on it:
cc1: note: unrecognized command-line option '-Wno-logical-op-parentheses' may have been intended to silence earlier diagnostics

Replying to kencu:
this looks like that same error we have been seeing for several years with the ODR issue with libstdc++ in libgcc on some systems.
The only fix for now is to use the binwrapping in legacysupport, which can work sometimes. Look at the cmake Portfile to see how to do it, as one example. In this case, looks like an intermediate build product is failing, and that is always harder.
As you have heard, Iain is working on this ODR issue (along with 1.2 million other things). No timeline or promise that it will ever be fixed, however.
Thank you. Yes, these malloc errors look familiar. Usually build fails with them though. Here it appears to go through completion. I will see if there are some tests for rakudo to check if it works as supposed to.
- S. If we manage to fix
libcxxfor PPC, that will solve the problem? Iain said that he backported an option to uselibcxxfromgcc12to earlier versions (throughgcc10?).

libcxx has no ODR issues with libstdc++, so you’re OK there.
What is much less OK is that nobody anywhere has ever built anything using gcc on ppc against libc++. Never.
So it’s a complete no-mans-land of uncertainty. Many, many issues can be expected. Every single port will need to be quite thoroughly tested, especially ports that other things depend on, like compilers, linkers, assemblers, glib2, etc.
For me… that is a very large amount of work, esp compared to installing a current debian on ppc64 which is extensively tested, has qt6, llvm, rust, etc…
It’s all in how you choose to spend your remaining years, really.

Yes, this is understandable.
By the way, I remember that you built simple ports for ppc with an old clang (3.5? 5?) and they linked to libcxx. But eventually that endeavor failed. Was it that more complex ports failed to build or even simple ones did not actually work?
