Sidenote: if this is an MPI program, you should be using mpic++ to
compile it.
No, this is not a large assumption.
Regardless of whether hello.cpp is an MPI program or not, you used g++
to compile it with no other options. ld then complained about some
linker option. g++ is the one who invokes ld. At no point were any
LAM commands used. Any LAM header files used (e.g., "mpi.h") would not
affect how your linker is invoked because we don't use any pragmas --
just plain, vanilla C and/or C++..
Hence, none of this has anything to do with MPI or LAM -- it's 100%
your C++ compiler.
So based on the information you provided, the problem is likely to be a
faulty installation of g++. Try "g++ -v hello.cpp".
