This may work, testing now:

		if {${os.major} == 10 && ${build_arch} eq "ppc"} {
		    puts $makeINC "TARGET = PPCG4"
		    puts $makeINC "HOSTARCH = PPCG4"
		}

[kencu (Ken)]

does this actually work in rosetta, or just 10.6-for-PPC? I thought it would have to be configure.build_arch to work in rosetta.

[kencu (Ken)]

or maybe you have an installation of macports on 10.6 Intel with ppc set as the build arch in macports.conf I guess….

Replying to kencu:

On 10.6 PPC this is not needed, openblas builds fine there.

At the moment I only have access to 10.6.8 Rosetta, so fixing ports for it. (I am out of Taiwan, and only got Intel MBP with me.)

Yes, exactly.

That -march=native flag comes from x86-specific build settings. Apparently because the build system identifies Host with x86. Specifically, Makefile.system has this:

# On x86_64 build getarch with march=native unless the compiler is PGI. This is required to detect AVX512 support in getarch.
ifeq ($(HOSTARCH), x86_64)
ifeq ($(findstring pgcc,$(HOSTCC))$(findstring nvc,$(HOSTCC)),)
GETARCH_FLAGS += -march=native
endif
endif

(And Cmake version has the same, though not used by Macports.)

Build is successful on 10.6.8 Rosetta now:

​https://github.com/macports/macports-ports/commit/018a7046599b062aa6f5af6e6de174c3edcc20b2 caused a regression (see #66903).
There is a ​pull request that attempts to fix the problem.
However, I have no way of testing it.
@barracuda156, could you please take a look?

No revbump since port either builds correctly or not at all.
