Try this

myprog : myprog.o mylibrary.o
        gcc myprog.o mylibrary.o -o myprog

myprog.o :
        gcc -c myprog.c

mylibrary.o :
        gcc -c mylibrary.c

Try to add -o after the other calls to gcc. Also, be sure you typed \t (tab key) in the indentation (not white spaces, but a real tab char). Be sure your text editor is not configured to use white spaces instead of tabs if this is the case.

myprog : myprog.o mylibrary.o
    gcc myprog.o mylibrary.o -o myprog

myprog.o : myprog.c mylibrary.h
    gcc -c myprog.c mylibrary.h -o myprog.o

mylibrary.o : mylibrary.c mylibrary.h
    gcc -c mylibrary.c -o mylibrary.o

Please, when writing a question, never forget to tell the error messages you get. This helps identifying the problem and give an accurate answer.

I hope this helps you. Take care, Beco
