Salut Gilles,Thanks for the bug report and for the patch.Which build-dependencies do you use to build the xmds2 package, in order to reproduce the FTBFS issue? The package builds fine against the libhdf5-dev and libhdf5-mpi-dev packages currently in experimental.
I use a local repo for the rebuilt reverse-depedencies.Plus a dedicated sbuild chroot with unstable + experimental + local repo, and HDF5 packages in experimental Priority-Pined, as well as all the packages in the local repo.
I rebuild all the reverse dependencies in the order given by the ben file and upload them into the local repo. So xmds2 is rebuilt against:
* hdf5 2.1.0 in experimental * h5py rebuilt against hdf5 2.1.0 * octave rebuilt against hdf5 2.1.0 Best, _g.
