[bug#28045] [PATCH] gnu: Add openfoam


From: Ludovic Courtès
Subject: [bug#28045] [PATCH] gnu: Add openfoam
Date: Thu, 07 Sep 2017 13:57:10 +0200
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/25.2 (gnu/linux)

Hi Paul,

I made the modifications below (mostly cosmetic) and built it locally.

However, the resulting layout, with /OpenFOAM-4.1 at the root and
essentially all the source tree beneath it, is unsatisfying.

Would it be possible to follow a layout closer to what we usually do:

  /gnu/store/…-openfoam-4.1
    bin/
    lib/
    share/
    etc/

If the answer is “no”, or if that would take an unreasonable amount of
work which should really be upstream’s job, then I can understand and we
can make an exception.

Or perhaps there’s a middle ground we could find?  For instance, we
install the tree to lib/openfoam-4.1, and then create bin/ as a symlink
to lib/openfoam-4.1/platforms/linux64GccDPInt32Opt/bin?  Would that
work?

Thank you!

Ludo’.
