openmpi in archlinux is not built with thread support (See, but this package is built with -DSCOTCH_PTHREAD. This will result in errors in openfoam like the following:

ERROR: SCOTCH_dgraphInit: Scotch compiled with SCOTCH_PTHREAD and program not launched with MPI_THREAD_MULTIPLE

A workaround is to add the following into build()

sed -i "s,-DSCOTCH_PTHREAD,,g"

@jdarch added option staticlibs. Is there a low-volume feed for PKGBUILD changes that packagers should watch?

jdarch commented on 2014-01-26 15:11

The default makepkg options will remove .a libs from the package, so eventually no lib will be in the package by default

Solved adding
export MAKEFLAGS="-j1"

According to this

Please update PKGBUILD.

I'm trying to compile but I get this error:
«no rule specified for target «», needed bt «main_esmumps». Stop.»
[translated from my language on the fly].

This is probably related to recent improvements.
Any hint? :)

Gug, I have made those two improvements, thanks.

And maybe copy esmumps.h and *esmumps*.so to the install prefix directory as it is not done by make install. (scotch bug ??)

gdolle commented on 2013-08-05 09:06

Hi, the libraries "" and "" are missing and required by mumps. It's not precised in the Install note, but I think we should add

make esmumps
make ptesmumps

to the pkgbuild.

Sorry for double post but fixed by symlinking

# ln -s /usr/lib/openmpi/ /usr/lib

I can't build this :

./ptdummysizes library_pt.h ptscotch.h
./ptdummysizes: error while loading shared libraries: cannot open shared object file: No such file or directory
make[2]: *** [ptscotch.h] Errore 127

but openmpi is installed. Could someone help me to figure this out ?
