Linking Objects

You can use the f77 driver command to link edit separate objects into one

executable program when any one of the objects is compiled from a Fortran

source. The driver recognizes the .o sufﬁx as the name of a ﬁle containing

object code suitable for link editing and immediately invokes the link editor.

The following command link edits the object created in the last example:

% f77 -o myprog main.o rest.o

You can also use the cc driver command, as shown below:

% cc -o myprog main.o rest.o -lF77 -lU77 -lI77 -lisam -lm
