If you're on 10.5, then "assuming 10.6" seems wrong and likely the source of the problem. Per ​https://lists.macports.org/pipermail/macports-dev/2016-March/032621.html,

dyld_stub_binder only exists for i386 and x86_64 on OSX. It was added to libSystem in SnowLeopard.

I have attached the log, I tried to build g95 on 10.5.8 PPC. (Though I do have 10.6 PPC, I have been requested not to report 10.6 PPC-specific problems here. So I build problematic ports on 10.5.8 and report when they fail on Leopard.)

[ryandesign (Ryan Carsten Schmidt)]

-macosx_version_min not specificed is also interesting (not only for the typo of "specified") but because MacPorts already sets MACOSX_DEPLOYMENT_TARGET='10.5' in all phases, which is supposed to be equivalent to the compiler flag -mmacosx-version-min and the linker flag -macosx_version_min.

From closer inspection of the log, I see that MACOSX_DEPLOYMENT_TARGET is actually not getting set here. And this is because the failure is occurring in code run by a pre-configure block. The block of code goes to some lengths to attempt to replicate what MacPorts does in the standard phases, including setting several of the usual environment variables, but it has neglected to set MACOSX_DEPLOYMENT_TARGET.

[kencu (Ken)]

agreed, the deployment target needs to be properly set (and macosx version min) for the right linker symbols to be chosen for 10.5.

that is likely the fix here.

(Also, this might fix PPC 10.5 but still leave PPC 10.6 broken, as PPC 10.6 is often not the same as a current Intel 10.6, and symbol assumptions based on os version are incorrect there sometimes. This is what I had to tweak in gcc7 for PPC 10.6, and this is a big part of why tickets sgainst 10.6 PPC would eventually frustrate people trying to help you.)

I'm working on it.

(and macosx version min)

Really? Just setting the deployment target is not enough? I thought they were equivalent.

In 2d54435f35507bbd16af545376070b0234ba5521/macports-ports (master):

g95: Set MACOSX_DEPLOYMENT_TARGET

See: #64188

Also use system's -W argument instead of running cd manually.

Let us know if that changed anything for you.

Thank you, it builds now:

36-85:~ svacchanda$ port -v installed g95
The following ports are currently installed:
  g95 @0.94_1 (active) requested_variants='' platform='darwin 9' archs='ppc64' date='2022-03-19T21:09:04+0800'

We have to fix download website however in portfile, since the old ftp is down. I used @0.94 from here: ​https://fossies.org/linux/misc/g95_source.tgz/

Looks like the domain name has been taken over by someone else and it is delivering a 200 OK response for any URL, including the URL of the old distfile. But it's a different problem than the one this ticket is about. File a new one.

I used @0.94 from here: ​https://fossies.org/linux/misc/g95_source.tgz/

If you'd like to propose updating the port to a new version please file a new ticket or pull request.
