Thank you Ralph and Samuel.
Sorry for the complete newbie question.
The reason that i wanted to study openMPI is because i wanted to make open MPI
support nodes that are behind NAT or firewall. If you guys could give me some
pointers on how to go about doing this i would appreciate alot. I am
considering this for my thesis project.
Sincerely,
LEO

"CFLAGS=-pg -g")
If you do a "./configure --help" you will get a complete list of the configure
options. You may want to turn on more things than just enable-debug, though
that is the critical first step.

Hi,
Let me begin by stating that I'm at most an Open MPI novice - but you may want
to try the addition of the --enable-debug configure option. That is, for
example:
./configure --enable-debug; make
Hope this helps.

Hi everyone,
I am trying to understand the openMPI code so was trying to enable debug and
profiling by issusing
$ make "CFLAGS=-pg -g"
But i am getting this error.

Is there any other way of enabling debugging and profilling in open MPI.
