I’ve got netloc built with hwloc support, but lsnettopo fails silently.  With verbose on, I get the following:

./lsnettopo -v -f


  Input Directory  : ./

  Export type      : screen


  Found 0 Networks.


Is there more documentation on what else may be required or how I can debug?  I’m building on an RH5 system which may be part of the issue, not sure.


hwloc (built at the same time, and what I used to build netloc) works fine and can see my IB adapter.
