Once you have configured Spheral++, building is simply a matter of executing make. Spheral++'s build system is based upon Gnu's make, which is
available on most systems. On a Linux based system make is the Gnu make,
while on many other systems Gnu make is installed as gmake. Building the
code from scratch can be quite a long process, particularly while building all
the third party packages. Fortunately, if you are building on a multiprocessor
SMP machine you can take advantage of Gnu make's parallel build facilities via
the -j option to vastly speed up the compile process. For instance, on a
typical AIX machine at LLNL a serial build might take several hours. However,
by building 10 way (gmake -j 10), the full compile can be completed in
less than half an hour.
