C Libraries

In general, libraries are created from many library source files, and are either built as archive files (libmine.a) that are statically linked into executables that use them, or as shared object files (libmine.so) that are dynamically linked into executables that use them. To link in libraries of these types, use the gcc command line options -L for the path to the library files and -l to link in a library (a .so or a .a):

-L{path to file containing library} -l${library name}

For example, if I have a library named libmine.so in /home/newhall/lib/ then I'd do the following to link it into my program:

$ gcc -o myprog myprog.c  -L/home/newhall/lib -lmine

You may also need to specify and include path so the compiler can find the library header file: -I /home/newhall/include
