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.
