[Octave-bug-tracker] [bug #38928] configure -> hdf5 doesn't handle path through

[Mike Miller]

Follow-up Comment #22, bug #38928 (project octave):

I followed some of the discussion when the Debian maintainers were overhauling
the HDF5 packaging, but got lost somewhere along the way (it's a confusing
library).

Here is the end of the conversation from back in June:

https://lists.debian.org/debian-science/2014/06/msg00014.html
https://lists.debian.org/debian-science/2014/06/msg00018.html

The first message says that since all users of HDF5 will have to rebuild
against libhdf5.so.8 anyway, might as well require them to use the new -I and
-L flags.

The second message (and last word on the thread) says yes, but this is still a
work in progress and some things could still be done. One possibility raised
was having yet another library called hdf5 that would redirect to the proper
serial/parallel library, and restore the ability of users to link with just
-lhdf5.

I think one of the motivators for not using alternatives is that these
libraries really are not drop-in replacements of each other. If I build Octave
using the serial library, it will probably work with one of the parallel
libraries, but definitely not the reverse.
