Looking at the changes from 1.0 -> 1.0.1, it doesn't look like any interfaces changed:
https://svn.open-mpi.org/trac/hwloc/changeset?old_path=/branches/v1.0&old=2100&new_path=/branches/v1.0&new=HEAD Per the Libtool rules cited here (scroll down to the "Shared Library Version Number" section): http://www.open-mpi.org/software/ompi/versions/ I think that hwloc's Libtool version number should go from 0:0:0 to 0:1:0. Can someone sanity check to ensure that's right? -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
