title: No targets specified and no makefile found
body: <p>I have a make file that contains this code:</p>
  
  <pre><code>all: main.o Etudiant.o
      gcc -lobjc -o program main.o Etudiant.o
  main.o:main.m Etudiant.h
      gcc -c main.m
  Etudiant.o:Etudiant.m Etudiant.h
      gcc -c Etudiant.m
  </code></pre>
  
  <p>When I write this in the shell command:</p>
  
  <pre><code>$make
  </code></pre>
  
  <p>I got this:</p>
  
  <pre><code>make: **** No targets specified and no makefile found. Stop.
  </code></pre>
  
  <p>How do I fix this?</p>
