I'd build against the system libhwloc, if only for consistency with other things using hwloc. However, don't --disable-... options get passed to sub-configures (possibly with a warning at higher levels)? I guess that's what Gilles meant. > Maybe we should just force several enable_foo=no when OMPI invokes > hwloc's configury.

After much head scratching, I found that mysterious bus errors crashing SGE daemons seemed connected to them, and the crashes went away when I rebuilt the hwloc library without the stuff. [I didn't think I could make a useful bug report.] _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
