Bug#917985: openfoam: Openfoam should not build (nor skip) dummy libraries

[littlejohn75 at laposte.net]

Package: openfoam
Version: 4.1+dfsg1-2pre~6.gbpa01bff
Severity: normal

Dear Maintainer,

The libopenfoam package installs  some files with paths derived from upstream ::

Libraries in questionable paths

/usr/lib/openmpi-system/libPstream.so
/usr/lib/openmpi-system/libptscotchDecomp.so

Libraries which can be taken off the build in Debian

/usr/lib/dummy/libMGridGen.so
/usr/lib/dummy/libPstream.so
/usr/lib/dummy/libmetisDecomp.so
/usr/lib/dummy/libptscotchDecomp.so

A Debian system should not have specific directories such as openmpi-system
or dummy.

git repository git at salsa.debian.org:littlejohn75-guest/openfoam.git contains
a number of patches ::
54_no_dummy_mpi.patch   (get rid of FOAM_MPI nonsense )
60_no_SCOTCH_ROOT.patch
61_no_metisDecomp.patch
62_no_dummy_decomposeMethod.patch
64_no_dummy_libdir.patch
  to get rid of dummy compatibility libraries with software not in Debian.

There are also some modifications of how to link the numerous programs and libraries
namely
 56_link_dl.patch  (get rid of zillions warnings about -ldl )
 58_simplify_LINK.patch  
 72_unused_lib_deps.patch  (do not link with a library if no symbols are used )


For the problem of potential name collisions with other packages, /usr/bin/noise
or /usr/bin/pdfPlot or /usr/lib/libsampling.so for instance, I wil open another
bug number.
