For what it's worth, you can work around that (using GNU tools) by adding -Wl,--as-needed to LDFLAGS on configure. There's a lot of similar instances, and it would be good to tidy them by only linking against what's necessary, even if it doesn't help startup. That's probably tedious but should be a straightforward way to contribute, in case anyone's interested. It seems we mostly don't believe in packaging round here, but you can see easily by running rpmlint (or the dpkg equivalent? -- I forget): $ vagrant ssh -c 'rpm -q openmpi; rpmlint openmpi | grep -c unused-direct-shlib-dependency' openmpi-1.10.2-2.fc24.x86_64 144
