For creating libraries for static linking, you need to use "ar" to
archive the files in a ".a" file.  An ar archived file is just a
simple collection of object files, there's no information needed to
resolve so you don't need gcc/ld to create the library. The syntax for
"ar" is somewhat similar to "tar". You need something like:

ar rc something.a list_of_.obj

then link your program with -lsomething
