How are the names of system libraries abbreviated on the gcc command line? Where does gcc search for libraries named in this manner? Describe how to specify your own library on the gcc command line. Libraries have names such as lib xxx .a or lib xxx .so . To link on the com- mand line with a library, first strip away the lib prefix and the .a or .so suf- fix; then prefix the remaining name with –l , as in –l xxx . By default, gcc searches the /usr/lib directory for libraries. When you spec- ify –L pathname on the command line, gcc searches the pathname directory for each instance of –L . To specify a library in /home/mine named libyyy.a , for example, you could use either of the following command lines: $ gcc -o myprog myfile.c -L/home/mine -lyyy $ gcc -o myprog myfile.c /home/mine/libyyy.a 5.
