[mvapich-discuss] mvapich2 1.9 and pgi 13.10: compilation problem

[Carmelo Ponti (CSCS)]

Dear Jonathan

You are perfectly right. I found the libtool file called libpmi.la which
include the -pthread flag. There are also two other files .la
(libslurm.la and libslurmdb.la) with the same flag (see the attached
file the three libtool files). In detail I found the following two lines:

# Linker flags that can not go in dependency_libs.
inherited_linker_flags=' -pthread'

# Libraries that this one depends upon.
dependency_libs=' /apps/pilatus/slurm/2.5.4-pam/lib/libslurm.la -L/apps/pilatus/slurm/hwloc/lib /apps/pilatus/slurm/hwloc/lib/libhwloc.la -lnuma /usr/lib64/libxml2.la -ldl -lz -lm -lpthread'

According my understanding, .la files are needed to work with static
libraries (but not only) which is not my case. Following your suggestion
I removed the "-pthread" flag on the three files and it compiled without
errors. I tried also to move the three files in a temporary directory
and it compiled as well.

Anyway before install it I need to understand more about this problem.
Especially I would like to know if it's save to copy back the three original .la
files.

regards
Carmelo
