on Microsoft Windows system, link with libf2c.lib;
|

on Linux or Unix systems, link with .../path/to/libf2c.a -lm
|

or, if you install libf2c.a in a standard place, with -lf2c -lm
|

-- in that order, at the end of the command line, as in
|

cc *.o -lf2c -lm
|

Source for libf2c is in /netlib/f2c/libf2c.zip, e.g.,
