I found the reason though I'm not sure what the proper fix is. In version 1.4 the hwloc-ls command is apparently a symlink to lstopo whereas in all later versions it is a symlink to lstopo-no-graphics. Using lstopo directly shows the graphical output options. How and where does the build process determine which of the two commands to link to? Regards, Dennis
