You don't use header files to make a library.  Header files are
#included by external programs to tell them what is in the library.  If
you specify a library as the target of a project in RHIDE, it will
automatically compile all source files to object code and use 'ar' to
put them into the library.  If you run from the command line, you should
compile to objects with the '-c' flag, and then use "ar rvs libmylib.a
obj1.o obj2.o obj3.o ..." to put them into a library.

To use a library, you should have one or more header files that declare
the functions and variables in that library, and then #include them in
your programs.  Finally, you must tell gcc to link the library to the
final executable.
