Re: [OMPI devel] PGI built Open MPI vs GNU built slurm

Gilles, With the additional information you provided about "dependency_libs", I agree that that either of the fixes you propose sound safe. -Paul On Mon, Jul 25, 2016 at 6:26 PM, Gilles Gouaillardet wrote: > Paul, > > in my environment, libslurm.la contains > > # Linker

Re: [OMPI devel] PGI built Open MPI vs GNU built slurm

Paul, in my environment, libslurm.la contains # Linker flags that can not go in dependency_libs. inherited_linker_flags=' -pthread' # Libraries that this one depends upon. dependency_libs=' -ldl -lpthread' so bottom line, it invokes the compiler with both -pthread and -lpthread iirc,

Re: [OMPI devel] PGI built Open MPI vs GNU built slurm

Gilles, My initial thought is that libslurm probably does require linking libpthread, either for for linking pthread_* symbols, or for proper *operation* (such as thread-safe versions of functions which override weak definitions in libc). If so, then neither omitting "-pthread" nor telling pgcc

[OMPI devel] PGI built Open MPI vs GNU built slurm

Folks, This is a followup of a thread that initially started at http://www.open-mpi.org/community/lists/users/2016/07/29635.php The user is trying to build Open MPI with PGI compiler and libslurm.la/libpmi.la support, and slurm was built with gcc compiler. At first, it fails because the
