esorepo gcc8, gcc9 Monterey

[dnfarias]

Hi all, a new MacOS user here. I have Monterey 12.2.1 version, with Macports 2.7.1-12. I've seen several tickets related to building gcc8 and gcc9 on new OSX versions, although I'm unsure on how to fix this problem with esorepo port. In particular, I was trying to do:

sudo port install esopipe-molecfit 

(it happens for other esopipe packages), and it fails at installing libgcc8 and libgcc9. I attach the whole main.log. In specific, the same issue as other tickets is:

From the patches and fixes, I suppose it shouldn't be hard to make this work.

the work required to get the older, no longer maintained gcc versions to build on newer systems has been declined upstream.

gcc11 and newer are supported. gcc10 has also been worked on and patches can be found, but an official release supporting newer systems is unlikely.

software that uses gcc should be updated or adjusted to use gcc11 as that is the supported default.

Ifvthe software cannot be updated, then that is a problem…

Thanks for your quick answer. Then it is a problem indeed.

this is a very unusual port that does most of it’s thing in a separate repository run by the authours.

you should best go to their website and post your issues, as macports is just a wrapper around their stuff…
