Using f77-c to do separate compilations
f77 -c file1.fYou now have 2 object code files named file1.o and file2.o.
f77 -c file2.f
Now you can link them together with this command:
f77 file1.o file2.oYou can use this strategy to save time as you develop your code. You only need to recompile those Fortran modules that have been changed since it was last compiled. Once you have recompiled any changed modules, you can link them together as shown above. As your modules get larger, doing this can save you quite a bit of time.
If you have many modules in your program, you may want to consider using 'make' which automatically figures out which of your modules need to be recompiled (by checking when they were last modified), and then links them.
If you want to learn more about 'f77' or 'make', you can read the manual pages by using the 'man' command:
man makeNOTE: On the RS/6000 workstations the name of the Fortran compiler is "xlf", and not "f77".
