Never mind the git-describe part, not sure why you're getting the<br>error though. Try running with "paraview -dr", just in case there's<br>something wrong with something that's being loaded automatically.<br><br>Utkarsh<br><br>On Mon, Oct 1, 2012 at 10:40 AM, Utkarsh Ayachit<br><<a ymailto="mailto:utkarsh.ayachit@kitware.com" href="mailto:utkarsh.ayachit@kitware.com">utkarsh.ayachit@kitware.com</a>> wrote:<br>> Odd, I cannot get to that version.
