[Nek5000-users] Prex problem

[nek5000-users at lists.mcs.anl.gov]

Thanks for the clarification.  To be sure I understand, when you open prex
from your terminal, the viewing frame appears,and you can start the session
ok (choosing a name for the session, clicking read previous
parameters...etc)?  Or does the viewing frame appear blank and there is no
text in the terminal log?

If you can start the session but not load the files, please send me the
stdout on the terminal of the session. (send off list to heisey at anl.gov)

If you cannot even start the session, you should check where X11 is
installed and that the path is set correctly in the prenek/makefile.

Best,
Katherine
