Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

Hi Raymond,

Charm++ does some source code generation as part of the process of compiling both itself and applications. This code generator needs to be compiled to run on the head node where you're doing the build. The primary Cray compiler generates binaries that may not be able to run on the head node, so the build logic has to call a compiler that can safely be relied on to generate code to run on the host system.

Hello,
  I am trying to build on our Cray using your new Shasta option.
I start with:

./build charm++ mpi-crayshasta --with-production

But I get the following at the end and I do not understand.  I am not using GNU.   Our default PrgEnv is "cray."  Any idea what I am doing wrong?  Thanks.
