Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

For users to be able to install octave packages, the octave should be compiled with the same C/C+++/Fortran compilers
as on their systems. Currently there is a mismatch (at least for darwin24 systems), see e.g.
Homebrew/brew#18943 (comment)

What did you expect to happen?

With self-compiled octave binary on the same system, it works fine:

Can you try doing

/usr/bin/sed -i '' \
  's/aarch64-apple-darwin23/aarch64-apple-darwin24/g' \
  "$(brew --prefix octave)/lib/pkgconfig/octave.pc"

and see if it helps?

[dasergatskov]

I tried it. Does not change anything.

[carlocab]

Yes, looks like the flags are baked into mkoctfile. You'll probably need to rebuild octave from source with something like

brew reinstall --build-from-source octave

[dasergatskov]

Yes, the paths are built into mkoctfile. I can build octave from source, though brew reinstall --build-from-source octave does not seem to be doing it.

[jgenc]

Had the exact same issue. Tried the solution @carlocab suggested, thankfully it worked for me. Not sure why however.

[mmuetzel]

mkoctfile retains some compiler and linker flags with which it was built as the default flags when it is calling a compiler or linker. That is a sensible default for most distributions.
If I understand correctly, it is not for Homebrew. Is that true?

Since the linker flags contain references to gcc, I'm assuming they might be inherited from the Fortran compiler (iiuc, that is gfortran). I could be wrong about that though.
Homebrew users can override those flags on runtime, e.g., by setting the environment variable FLIBS=" " (or by setting FLIBS to whichever Fortran library flags need to be used) while they run mkoctfile.

Does that work?
