No, actually, my report isn't about that issue at all. I'm not
talking about making an entirely statically built application. I'm
talking about a statically compiled Open MPI with a dynamically
linked application and OFED. Take a look at the output of mpicc -
showme -- it's not adding *ANY* -l or -L options for InfiniBand.
This is something wrong with Open MPI's configure, which has changed
since v1.2. On v1.2, the same commands result in:
[10:54] brbarret_at_odin:pts/27 v1.2> mpicc -showme
include -pthread -L/usr/local/ofed/lib64 -L/u/brbarret/Software/
x86_64-unknown-linux-gnu/ompi/devel/lib -lmpi -lopen-rte -lopen-pal -
libverbs -lrt -lnuma -ldl -Wl,--export-dynamic -lnsl -lutil -lm -ldl
[10:55] brbarret_at_odin:pts/27 examples> make ring_c
mpicc -g ring_c.c -o ring_c
