[pkg-boost-devel] Bug#490242: boost1.35: please build boost-mpi libraries

[Tilman Koschnick]

Package: boost1.35
Version: 1.35.0-5
Severity: wishlist

Hi,

it would be great if you could add support for the boost-mpi libraries
which are part of boost since version 1.35. I'd suggest linking against
OpenMPI, which is very actively maintained, both upstream and in Debian.

I have made a not very successful attempt to hack the debian package to
enable boost-mpi packages; my try is attached as a patch. The problem I
had is that boost-mpi consists of a libboost_mpi library, as well as a
libboost_mpi_python library, which in conjunction with a boost.mpi
python module provides a python interface to boost-mpi. Now, the two
different libboost_python versions with different suffixes complicate
things... I don't know if it wouldn't be easier in the long run to just
support the current python version in boost.

Unfortunately (well, not really ;) I am on vacation the next three
weeks, so I can't continue my trials, nor test anything you might come
up with before August.

Cheers, Til
