Subject: Allow the installation of libhdf5-serial and libhdf5-openmpi at the same time

Date: Mon, 02 Aug 2010 13:55:21 +0200

Package: hdf5
Severity: important

Hello,

More and more packages are using hdf5 packages.
Some of them (for example, Code Saturne) are using hdf5 mpi by default while
others, like Scilab, needs the serial one.

This is causing also some issues at build time. See bug #591164.

To reproduce it:
aptitude install libhdf5-openmpi-1.8.4 libhdf5-serial-1.8.4

By the way, if the ABI are compatible, #586149 might be the solution.

Thanks for considering this. 

If you need help on this, don't hesitate to ask.
Sylvestre

This bug blocks 2 RC bugs, and I don't see any other resolution path for
those RC than fixing this bug.
So I'm upgrading this bug to severity:serious too, to make sure it stays
on the radar.

WTF is the reason to both depend on serial and parallel flavors at
building time instead of the parallel version libhdf5-mpi-dev? 
Note that *if the ABI are compatible* is a wrong guess AFAIK: serial
and parallel versions have different shlib sub-dependendecies.
There are also many limitations in parallel edition: e.g. parallel
edition does not support pluggable compression in writing and does
not support variable length records, cannot coexists with
threadsafe and C++, and so on. I think the only safe and clean approach would be
having different lib names for MPI flavors, but upstream think
differently at the moment. I'm not intentioned to diverge about that,
which would require rdepends changing their building snippets forever
in Debian, and adopt other dirty tricks.

Both bugs marked as blocked have been fixed and transitioned to testing,
resetting severity to "important".
