py27-scipy @1.2.3: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]

Even after a selfupdate, an upgrade and a clean, I get the following error

--->  Building py27-scipy
Error: Failed to build py27-scipy: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_python_py27-scipy/py27-scipy/main.log for details.

main.log file attached.

There are a lot of warning but only one error I could spot in there:

I tried downgrading the errors to warnings again in recent OSes but without much luck so far.

Having said that, this version is EOL for about 6 years now so you shouldn’t really expect too much effort in keeping this functional. Why do you still need it, is there now way you can use a supported PY3 version?

Thanks for looking into it. I didn't realize it haf been EOL for so long as I didn't change my computer in a long time so the old version was ok.

I just used an LLM to convert my old python2.7 code into python3 and it seems to work fine. So on my side, you don't have to try to make it work anymore, scipy for version 3 is now sufficient for my needs.

Thanks again.
