RE: [mpi-21] ABI - call for working group
Hi,
I may have missed this in the trail, but I'm still unclear as to how a
morph layer loads the target library. Is this dlopen()?
Best regards.

Since you're distributing your software in binary form, you would
compile the morph layer yourself and distribute your software already
pre-linked with it. The morph layer would then adapt to your local
MPI when you install your software. At install time it would need to
have enough information about the local MPI to be able to link to it
but shouldn't need much more than that.
