Follow the installation procedures described in INSTALL:
do
./configure
make

but you can leave out the:
make install

The program will be located in src/ and named gibbsens,
there are several ways of starting it:

a) withtout argument: the program starts from the default parameters but you most probably don't want that
b) with a *.param files as argument: it starts with the parameters given in the file see example.param for an example
c) with "restart" as argument: the program then will start from a former run, but this feature is quite untested!

The program itself does the following on methods a and b it generates the simulation boxes and sets the desired number of particles
on a FCC lattice, and then it performs an initialisation phase where the step sizes are adjusted until we get a convenient
acceptance rate and until the melt factor is sufficiently small (i.e. the stuff is molten).

Then for all three a.b and c the simulation itself starts.

For a closer insight of the internals of this program take a look at doc/html/index.html


Have fun
