redefinition of ‘struct PMI_keyval_t’

Hi there,

Trying to compile Open MPI 2.0.2 with PMI support for Slurm (17.02.1), I get the following error.

$ ./configure --with-pmi --with-verbs --prefix=/share/software/openmpi/2.0.2
[...]
$ make

Does that sound familiar?

@kcgthb you may want to check if applying the patch from https://patch-diff.githubusercontent.com/raw/open-mpi/ompi/pull/3206.patch
to your Open MPI source tree fixes the problem. Otherwise the fix will be in the
2.0.3 update release.

See also #3207 and #3208 and #3212 for PRs onto other branches.

It actually does, thank you!

Looks like this has been fixed.

Hi there!
Looks like this is still there in Open MPI 2.1.0:
https://github.com/open-mpi/ompi/blob/v2.1.0/opal/mca/pmix/s2/pmix_s2.c#L33

It's in the 2.1.1 release that is about to be set free
