Its possible for ports to define specific environment variables, which 
will get set during the variable phases as that port builds. see


https://guide.macports.org/#reference.phases.configure

for more details.

for the specific issue here though, the canonical fix would be to add 
the linker option to the ldflags for a specific port. e.g.


configure.ldflags-append  -Wl,-ld_classic

that should be done inside a check on the Xcode version, so its only 
applied when needed. See e.g.


https://github.com/macports/macports-ports/commit/41cce53c601d6c407a48eaf7c705b45bec848dcb

where I did just this for the root6 port, and there it fixed the issues.

This will work for ports that are well behaved and respect the build 
flags macports sets. Unfortunately not all ports are and I have run into 
a number where the above does not work (e.g. looking at you py-scipy...)


cheers Chris

Hi,

Just incase any one else reads this, anything you add to your user 
profile will nit have any effect on port builds, as these do not run 
as your user. So don’t try this expecting it to fix port builds.

For now, use Xcode 15 and its command line tools and try to enforce 
the old linker by defining the following environment variables:


  export MACOSX_DEPLOYMENT_TARGET=12
  export OTHER_LDFLAGS=-Wl,-ld_classic

You may place them into your ~/.profile file. I hope this helps.

Some have suggested reverting to Xcode 14.3.1, to work around those 
issues.


But under macOS Sonoma, that does not seem to be an option: After 
replacing Xcode 15 with Xcode 14.3.1, and similarly for the 
command-line tools, if I open Xcode 14.3.1, I get an error that this 
version of Xcode will not work with the OS (Sonoma).


Is there some other work-around?

Several ports I had been trying tore-ininstall under macOS Sonoma (in order to 
re-install, finally, maxima and wxMaxima,
still seem to be failing configuration, even though I did add the two exports 
to my ~/.profile (and, of course, after restarting the shell), namely:

ipopt, sbcl, scalapack, scotch

I've updated existiing, or filed new, tickets about that.

Anything else to try?

Hello Murray,

How are you? As mentioned in the previous posts on this list, please see 
Apple’s comments on the new linker issue:

https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes#Linking
Xcode 15 Release Notes | Apple Developer Documentation
developer.apple.com

For now, use Xcode 15 and its command line tools and try to enforce the old 
linker by defining the following environment variables:

  export MACOSX_DEPLOYMENT_TARGET=12
  export OTHER_LDFLAGS=-Wl,-ld_classic

You may place them into your ~/.profile file. I hope this helps.
