I'm not sure that would not break in a very odd and tricky way intricated dependencies (e.g. building using headers of third parties that depend on and include different hdf5 flavors). I would avoid that. It is much more sane diverging headers names too and patch what ever is needed to be patched to use the right flavor. -- Francesco P.

Bug#586149: Please consider the usage of update-alternatives for hdf5 libraries
severity 586149 serious retitle 586149 Conflict between hdf5-tools and libhdf5-mpi-dev prevents several packages from building block 661301 by 586149 thanks Hi again, Because this causes other packages to FTBFS, it really needs to be an RC bug. -Adam On Sun, 2012-02-26 at 00:12 -0500, Adam C Powell IV wrote: > Hi, > > There's a better way to do this by just having different shared library > file names and sonames for each of the shared library packages.

Bug#586149: Please consider the usage of update-alternatives for hdf5 libraries
Hi, There's a better way to do this by just having different shared library file names and sonames for each of the shared library packages. Then the -dev packages can conflict, while one can install multiple packages using the different shared libraries simultaneously, not one-at-a-time as update-alternatives would do. Note this would also allow simultaneous install of hdf5-tools and libhdf5-mpi-dev which is required to build several HDF5 reverse-depends, such as med-fichier. This represents a major regression vs. 1.8.6 and should be fixed as soon as possible. I'll work on a patch tomorrow and will post it to this bug. -Adam -- GPG fingerprint: D54D 1AEE B11C CE9B A02B C5DD 526F 01E8 564E E4B6 Engineering consulting with open source tools http://www.opennovation.com/ signature.asc Description: This is a digitally signed message part ___ Pkg-grass-devel mailing list Pkg-grass-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-grass-devel

The right answer is a different name for mpi/not-mpi implementations, but upstream is still far from converging on that and I'd avoid implementing a debian-only flavor about that. -- Francesco P.

Package: hdf5 Severity: wishlist Hello, It would be nice if you could consider the usage of update-alternative for the hdf5 libraries. For now, it is not possible to have both hdf5 and hdf5-mpi packages on the same system. This would allow this and improves the switch between the various implementations improvements. I implemented this with success for linear algebra libraries: http://sylvestre.ledru.info/blog/sylvestre/2010/04/06/update_of_the_linear_algebra_libraries_i If you agree, I could try to do that for you for hdf5.
