title: Make Error 127 when running trying to compile code
body: <p>This semester I got this new subject where we get to work with Discovery STM32 F4, and we are still in the phase of setting it up. But I have this problem in the beginning.</p>
  
  <p>When I try to compile this "blink" code I get this error:</p>

  <p>So, as I got it so far, we are using this shortcut command "make" to compile code, and we were given instruction to set it up as it's shown in images below:</p>

  <p>Can anyone see what's the problem here? </p>
