Okay, here's what you do. You compile all the source files for your functions:
gcc -c [-whatever] func1.c
gcc -c [-whatever] func2.c
...

Then you use `ar' to make them into a library.
ar qc libfoo.a func1.o func2.o ...

Finally you use `ranlib' to add the dictionary to the library.
ranlib libfoo.a
Note that you can do the same thing with the `s' flag to `ar'; see its docs.

To use your library, #include your header file in the source file, and when
linking, add `libfoo.a' to the list of files. Alternatively you can copy it
to your lib directory, and link with the option `-lfoo'.

Long?!? You haven't been reading this ng long :) That's a really short
posting compared to many I see here. A quite reasonable length.
