Hi Frank,

Well, I have in mind developing/testing on my mac laptop (Lion) and
doing real computation on the Ohio Supercomputer Center (OSC)
clusters.  I had tried to get WaveDemo working on my laptop and have
trouble getting things to build.  So I have now switched to the OSC
frontend and am trying to get the same demo working there.  So, my
questions below are relative to building there.

On the OSC machine I have downloaded the development version.  I also
downloaded the WaveDemo.th.  In the Cactus directory I have done the

make WaveDemo THORNLIST=./WaveDemo.th  >& makewavedemo.out

with the makewavedemo.out file attached.  The upshot is that it
detects some fortran compile options it does not like and I think that
probably is sufficient to make BLAS, LAPACK, and LORENE fail to

I have a feeling that there is a need or needs to supply more info to
make about where things are, e.g. mpi, which fortran (can use ifort
and the rest of the intel compilers if better), and maybe other

Can you please advise?
