    How to compile with libraries (*.a) with gcc?

    I'm fairly new at this gcc stuff. So I successfully compiled a set of libraries from the source. How do I use them in my program? Do I need to include the library headers in my program? What arguments/options do I pass to gcc?

    Say for example your library is in
    and it's corresponding header file is in

    To compile something using those, say
    #include <thingy.h>
    int main ( ) {
        return 0;
    You would compile with
    gcc -I/home/me/work/thing/inc main.c -L/home/me/work/thing/lib -lthingy
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
