Please post a complete, clean, build log for the port in question.
In general GCC should not be used to build c++ (*) as doing so leads to
these c++ runtime mis-matches. You should use clang for c++ (and c as
well, although there is no runtime issues there).

* The latest GCC versions now actually support building against libc++,
the clang runtime, which would make this possible in theory. It needs
support in base though
(https://github.com/macports/macports-base/pull/275) so cannot be used
until that is available.

Installing CalculiX with a clang variant is successful, however when

You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt: CalculiX @2.18+docs+examples+gcc12
Continue? [Y/n]:
Choosing ‘Y’ puts it into and endless re-install. Adding
'configure.cxx_stdlib macports-libstdc++’ seems to fix things.
1. What is causing this?
2. Should the compilers group be removed and stick with clang?
3. What changes to the portfile would need to made to permit either
compiler variant?
Thanks,
Mark
