Well, actually for instance Debian builds once with -static, and once with -shared, and installs both... BTW, I guess it wasn't attempted to make OMPI plugins work on windows? The nightmare is even worse there... > 2. If --enable-shared (which is OMPI's default), we build plugins as DSOs and > do not link them against libmpi.so (and friends). > > 3.

This is cases #2, #5, #8, and #11 in table 1. Don't these vendor-provided DSO need to use some OMPI functions? That said it looks a not too bad solution: avoiding loading plugins in the static case, but still allowing third-party plugins, and it's up to the user to make it work :) Samuel
