Could you try it? I.e.: - install 1.0.2 (or, better: 1.0.3rc) - compile and run a trivial hwloc app against 1.0.x - download and extract 1.1rc2 - change VERSION to be 1:0:1 - build and install 1.1rc2 over the 1.0.x install - run the same trivial hwloc app against the new library without recompiling/relinking it Does it work? -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
