Hey,
I am trying to determine if the C++ bindings of our LAM 6.3.2 are
broken. I can compile C++ programs and the ring example, but I can't
link them. When I try, this is the result:
$ hcp -o ring -fexceptions -Wno-deprecated
/pkgs/lam-6.3.2/examples/mpi2c++/ring.cc

I don't understand why these linking errors are happening when the hcp
wrapper is including libmpi++.a. These symbols seem to be in that
library.
Any ideas? Any help? Has this problem cropped up for anyone else?
Have I overlooked something?
