[Pkg-scicomp-devel] fw: gfortran transition release goal proposal

[Kevin B. McCarty]

Hi Riku,

Something I missed seeing in your original gfortran transition email,
that maybe was left out because it was so obvious...

I assume that the soname and filename of the library itself shouldn't
change, just as in the g++ transition, right?  So lapack3gf would
continue to contain /usr/lib/liblapack.so.3, and therefore the new
lapack3gf binary package (for instance) needs to Conflict and Replace
the old lapack3 to prevent dpkg overwritten file complaints.

Or is the plan to do this differently, renaming the library files and
sonames to preserve parallel installability?  I can imagine a lot of
scientists will be unhappy that they need to recompile all their old
locally built FORTRAN programs with a new compiler for them to keep
working ...

best regards,
