I'm glad that worked. I understand the confusion. The configure output could be better. It shouldn't be too difficult to cleanup. I filed a ticket so we don't forget about this issue. The ticket is linked below if you are interested: https://svn.open-mpi.org/trac/ompi/ticket/2807
Next time I cycle back to the C/R functionality I'll try to address it, but if someone else beats me to it then that should be reflected in the ticket. -- Josh On May 27, 2011, at 3:54 PM, Bill Johnstone wrote: > Hello, > > > Thank you very much for this.
