I have used the wrapper compilers ($FC=mpif90 and $CC=mpicc), even then i was getting these errors. Anyway I used -lmpi in place of -lmpich and the build was successful. Thanks a lot for your help :)

Cheers,

Better yet, the Open MPI team strongly discourages listing individual MPI libraries on the link line because we reserve the right to change them over time.

Instead, we *strongly* advise you to just use Open MPI's wrapper compilers, which will insert all the Right compiler and linker flags.  Then you don't have to worry about any of those pesky -I and -L options, especially when transitioning between different MPI implementations and versions of Open MPI.
