Pavan, <div><br></div><div>The error output I had observed was because debug mode was enabled inside hwloc. It appears that the hwloc debug mode is enabled by default when we do an svn checkout. This does not happen if we do an export instead. I believe you did an export and hence did not see the debug output. </div>
