Yes, understood, but my point here is that there could be multiple hwloc packages -- one that installs the core and some base set of lstopo plugins (probably not cairo and X). And then secondary packages install lstopo's cairo and X plugins. Hence, a sysadmin can choose whether to have cairo/X support (because presumably they will both pull in bunches of dependencies). But the user always runs "lstopo" and gets the choice of whatever outputs the sysadmin has chosen to install. >> But if I'm in the minority, no problem... >> >> If I'm not, I can work on a patch to see if it would be horribly >> disruptive... > > It would most probably not be, we already use a backend style, so it's a > matter of putting the code in separate plugins. That was my assumption. I am guessing/assuming that it's a matter of: - adjusting configury to use libltdl - building the back-ends as DSOs, installing them - adapting the back-ends to advertise their function pointers neutrally - adding a bit of dlopen-based logic to find/load all available backends -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
