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.

libtool: link: ( cd ".libs" && rm -f "mca_paffinity_linux.la" && ln -s "../mca_paffinity_linux.la" "mca_paffinity_linux.la" )
make[3]: Leaving directory `/home/Desktop/openmpi-1.3.2/opal/mca/paffinity/linux'

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