Did you mean --disable-shared instead of --disable-dlopen? And I am still confused. With "--disable-shared" I get a bigger static library than without it?

The --disable-dlopen option actually snips out some code from the Open MPI code base: it disables a feature (and the code that goes along with it). Hence, it makes sense that the resulting library would be a different size: there's actually less code compiled in it. > On Feb 24, 2015, at 2:45 PM, twu...@goodyear.com wrote: > > > I am setting up Openmpi 1.8.4.
