Quick answer: not easily. Long answer: There's not an easy way, but there are some facilities to help. I believe Oracle uses them when building binaries for Solaris. There is some documentation available on our Trac wiki: https://svn.open-mpi.org/trac/ompi/wiki/MultiLib https://svn.open-mpi.org/trac/ompi/wiki/compilerwrapper3264 The difficulty is that it's up to the user/admin to make sure the correct arguments are provided, as well as writing the wrapper script files to do the sharing.
