Package: dh-fortran-mod
Version: 0.23
Severity: normal
Hi Alastair,
could you revert the transition to gcc-12 for now and do it in parallel
with gcc switching to it by default?
Background:
src:pcl uses clang on armhf/el because it does not compile with gcc.
pcl build depends on libopenmpi-dev (through libvtk9-dev) and with this
libgcc-12-dev is pulled in (libopenmpi-dev -> gfortran-12 -> gcc-12 ->
libgcc-12-dev). But with libgcc-12-dev installed, clang expects to use
it and also needs libstdc++-12-dev which is not pulled in:
root@fenchel:/# echo "int main() {}" > broken.cpp
root@fenchel:/# clang++ broken.cpp
root@fenchel:/# apt install libgcc-12-dev

As a result src:pcl currently fails to build on armhf/el. This is
unfortunate cause it blocks the onetbb transition. I talked to ginggs in
IRC and he proposed to revert the gcc-12 switch of dh-fortran-mod.
Cheers Jochen

Closing this bug. The previous change that was rolled-back added a
"gcc-12" dependency that was premature.
This has been removed, but since then gcc-12 is now the default and the
transition/rebuild is underway.
