Re: [Pympi-users] softload_setup.py file

[Pat M. <pat...@ll...>]

The softload stuff is not built by default because it is hard to
make it work uniformily across OS's and MPI architectures.  So,
if you want it, you have to build it in a separate step.  I
don't consider this feature "working" as yet.  I need to update
the pyMPI_linker to fix some compiler issues.  In theory, it should
work like this.
