In the command for this target: libshm.a : libfile1.o gcc -Wall -c -lsocket -lnsl libfile1.c you're compiling only because you have the -c flag. No linking takes place, so gcc is informing you that it is ignoring the -lsocket and -lnsl linker flags. You don't need them in that command. All of the linking takes place in the command for this target: client1: client1.o libshm.a gcc -Wall client1.o -L. -lshm -o client Here you will want to use -lsocket and -lnsl because you're linking all of the parts into an executable, so you can't leave anything out.
