hi chetan and Nalin,
sorry for late reply.
i havn't done compiler optimisation till now. i used default
optimisation flag -O2. I will, now, check for other flags as you
suggest.
i did the tests for checking the credibility of mpi by checking the
value of pi in an example, given in "/MPI/mpich2-1.2.1/examples".
f77 and f90 correctly calculate the value of pi, but cxx doesn't
process the cxxpi.cxx file, to calculate the value of pi.
Following error comes ( i don't know what is the meaning of these
erros/errors, can you tell me few basic points this error massage
give? ):>
---------------------------error massage is as
