We only need universal for PPC on 10.5. Not on 10.6 (whether native or Rosetta).

which means that the condition from a Portfile

if {${universal_possible} && [variant_isset universal]} {

I assume that if you disable the universal variant by adding -universal, it will work.

I think it should be set to non-universal on darwin10 when build is for ppc, since ppc64 is not supported in any version of 10.6. That is, in the portfile, to unbreak it for everyone. Perhaps on Tiger also.

Perhaps.

Anyway, it works fine on BuildBot: ​https://build.macports.org/builders/ports-10.6_x86_64-builder/builds/153158

[ryandesign (Ryan Carsten Schmidt)]

Yes, but the Intel buildbot workers build for Intel whereas Sergey configures his Intel Snow Leopard system to build for PowerPC, hence the problem. (I believe this configuration is what he means when he uses the term "Rosetta".) Theoretically MacPorts supports the notion of cross-compilation but in practice many ports are not prepared to deal with that.

[catap (Kirill A. Korinsky)]

I've added into macports.conf the block to the end:

universal_archs
build_arch              ppc
cxx_stdlib              libstdc++
buildfromsource         always

and it literally switched off universal build, which disabled multilib and multiarch and allows to build it.

Also, at build log I see that it uses build folder, not build-ppc that means that it doesn't build universal build but configure string contains --enable-targets=powerpc-apple-darwin10,i386-apple-darwin10,x86_64-apple-darwin10 which is added by lines:

    set universal_targets ""
    foreach arch ${universal_archs_supported} {
        set universal_targets "${universal_targets},$merger_host(${arch})"
    }

    ui_debug "Selected targets: ${universal_targets}"

    if { [string length ${universal_targets}] > 0 } {
        configure.args-append \
            --enable-targets=[string replace ${universal_targets} 0 0]
    }

inside that if. That shuldn't be possible. Thus, I haven't see inside log a line Selected targets.

All of this puzzling me.

I have checked now, I have this is macports.conf on 10.6.8:

build_arch			ppc
universal_archs		ppc i386 x86_64

Why it is there is because darwinbuild is set to require universal build that includes Intel, and I hoped to fix it (the port is broken, as of now).

When port build gcc10-bootstrap 'configure.universal_archs=ppc i386 x86_64' should repeat your build. Am I right?

I've run that command and it uses build-ppc folder to build it => munuiversal PG works. This is the second hm from your log, because I haven't found any trace of that folder in it.

Let see how it goes on my end. I assume that it should fail relatively soon.
