This is the second suggestion to rebuild Slurm
The other from Åke Sandgren, who recommended this:
This usually comes from slurm, so we always do
perl -pi -e 's/-pthread//'/lap/slurm/${version}/lib/libpmi.la
/lap/slurm/${version}/lib/libslurm.la
when installing a new slurm version. Thus no need for a fakepg wrapper.
I don't really have the luxury to rebuild Slurm at the moment. How would
I rebuild Slurm to change this behavior? Is rebuilding Slurm with PGI
the only option to fix this in slurm, or use Åke's suggestion above?
If I did use Åke's suggestion above, how would that affect the operation
of Slurm, or future builds of OpenMPI and any other software that might
rely on Slurm, particulary with regards to building those apps with
non-PGI compilers?

Hi,
The -pthread flag is likely pulled by libtool from the slurm libmpi.la
<http://libmpi.la> and/or libslurm.la <http://libslurm.la>
Workarounds are
- rebuild slurm with PGI
- remove the .la files (*.so and/or *.a are enough)
- wrap the PGI compiler to ignore the -pthread option
Hope this helps

Greeting Open MPI users! After being off this list for several
years, I'm back! And I need help:
I'm trying to compile OpenMPI 1.10.3 with the PGI compilers,
version 17.3. I'm using the following configure options:
./configure \
--prefix=/usr/pppl/pgi/17.3-pkgs/openmpi-1.10.3 \
--disable-silent-rules \
--enable-shared \
--enable-static \
--enable-mpi-thread-multiple \
--with-pmi=/usr/pppl/slurm/15.08.8 \
--with-hwloc \
--with-verbs \
--with-slurm \
--with-psm \
CC=pgcc \
CFLAGS="-tp x64 -fast" \
CXX=pgc++ \
CXXFLAGS="-tp x64 -fast" \
FC=pgfortran \
FCFLAGS="-tp x64 -fast" \
2>&1 | tee configure.log
Which leads to this error from libtool during make:
pgcc-Error-Unknown switch: -pthread
I've searched the archives, which ultimately lead to this work
around from 2009:
https://www.open-mpi.org/community/lists/users/2009/04/8724.php
<https://www.open-mpi.org/community/lists/users/2009/04/8724.php>
Interestingly, I participated in the discussion that lead to that
workaround, stating that I had no problem compiling Open MPI with
PGI v9. I'm assuming the problem now is that I'm specifying
--enable-mpi-thread-multiple, which I'm doing because a user
requested that feature.
It's been exactly 8 years and 2 days since that workaround was
posted to the list. Please tell me a better way of dealing with
this issue than writing a 'fakepgf90' script. Any suggestions?
