Thanks for replying..
I tried deleting all the files that are related to protobuf and grpc in all
the bin and lib folders and tried installing it again.
1) When I install grpc first and then protobuf.. I'm able to install it
without any errors... But i'm getting the below error while running the
helloworld program in cpp exmaples.
Undefined symbols for architecture x86_64:

2) When I install protobuf first and then grpc i'm getting the same error
which i first posted in this thread (during executing make command in grpc
directory ).
