gcc12 fault?

[Ken Cunningham]

what you see is difficult to explain, unless the PATH changed between the two tests.

if

'which gcc' gives /opt/local/bin/gcc

then

gcc --version

should give exactly the same as

/opt/local/bin/gcc --version


Now you know that /opt/local/bin/gcc will not actually exist, unless you have "selected" a gcc in macports to be your default gcc.  You probably want to unselect that if you did select one, as having it always set can cause problems that can be hard to debug. I do set a selected gcc sometimes, but unset it right after.

Versions of gcc older than gcc12 failed (as advised in the resintall), so I installed gcc12, ran port select to activate gcc12 and gfortran12. All ok so far.
