Figure 1-3 Link Editing
Both f77 and cc use the C link library by default. However, the cc driver
command does not know the names of the link libraries required by the
Fortran objects; therefore, you must specify them explicitly to the link editor
using the –l option as shown in the example. The characters following –l are
shorthand for link library files as shown in Table 1-1.
