Compiling gosia

==Compilers==

Gosia can usually be compiled without any special compiler switches.  Using <tt>g77</tt>, type

<tt>g77 -o gosia gosia_20081208.10.f</tt>

or similar for a different version number.

The <tt>gfortran</tt> compiler is installed more often than g77 on some new Linux systems.  In this case, the command is 

<tt>gfortran -o gosia gosia[version].f</tt>,

where <tt>[version]</tt> is the version number as in the first case.

==System requirements==

The system on which Gosia and its companion programs will be run should have a 64-bit processor, ''and'' the operating system should be 64-bit as well.  It is possible that a 32-bit operating system installed on a 64-bit machine may cause a loss of accuracy by treating registers as 32-bit.
