Hi,

Version 6.1.0.svn.5272.dfsg-1 of this package was built successfully in Debian:
https://buildd.debian.org/status/logs.php?pkg=elmerfem&ver=6.1.0.svn.5272.dfsg-1
https://buildd.debian.org/status/fetch.php?pkg=elmerfem&arch=armel&ver=6.1.0.svn.5272.dfsg-1&stamp=1313765751

So the problem is in build dependencies or in Ubuntu specific patches.

Unfortunately there is only useless diff between 6.1.0.svn.5272.dfsg-1ubuntu1 and 6.1.0.svn.5272.dfsg-1ubuntu2:
https://launchpadlibrarian.net/78985492/elmerfem_6.1.0.svn.5272.dfsg-1ubuntu1_6.1.0.svn.5272.dfsg-1ubuntu2.diff.gz

But as we can see in change log there were no changes related with MPI in version 6.1.0.svn.5272.dfsg-1ubuntu1:
http://changelogs.ubuntu.com/changelogs/pool/universe/e/elmerfem/elmerfem_6.1.0.svn.5272.dfsg-1ubuntu2/changelog

So I think the problem is in mpi-default-dev package, but not in elmerfem.

Regards,
Boris

Hmm, or compiler options in Ubuntu differ from Debian ones.

the library needs to be linked against the library providing `ompi_mpi_comm_world', which it doesn't do. Maybe not seen on Debian, because it's not built using --as-needed by default.

Exactly. This compiler option is not enabled in Debian by default.

Ubuntu Oneiric is not supported anymore.
