libcalceph-fortran-dev is declared Multi-Arch: same, but fails to
coinstall.

The file /usr/include/calceph.mod is shared by libcalceph-fortran-dev
version 4.0.4-2 as present in trixie and version 4.0.4-2+b1 as present
in forky|unstable with varying content.

Please ensure that shared files have bit-identical content across
architectures, move architecture-dependent files to
architecture-dependent paths or remove the Multi-Arch: same field.

Kind regards

Helmut Grohne

Hi Helmut,


Thanks for uncovering this issue. Indeed the .mod files are compiler
generated so they should be arch-dependent, and hence do not belong in
`/usr/include` (which is where upstream installs it).

My question is what's the canonical location for such files on Debian?
Being arch-dependent, they probably belong somewhere under ${libdir},
such as:

  a. ${libdir}/finclude

  b. ${libdir}/${packagename}/

  c. ${libdir}/${packagename}/include

Is there a preference for which is location would be most appropriate,
or conventional, for Debian packages? I'm in contact with the upstream
developers also, so whatever the fix is, it can be applied upstream also.


Thanks,
