  <p>While trying to install the <code>makefile</code> provided for <code>rpi-tftgl</code> in <code>rpi-tftgl/tftgl</code> directory I am getting this error when I run <code>make</code> command. 
  Here is the link of my captured image of pi terminal window showing the exact error:</p>

  <p>Following is the error i recieved when I execute <code>make</code> command :</p>
  
  <pre><code>gcc -c src/tftgl.c -o src/tftgl.o -I/opt/vc/include -I. -Iinclude -D:0 -O3
  &lt;command-line&gt;:0:1: error: macro names must be identifiers
  Makefile:18: recipe for target 'src/tftgl.o' failed
  make: *** [src/tftgl.o] Error 1
  </code></pre>
  
  <p>Can I get a solution for this or any recommendation for any other source or links which I can follow to interface ssd1963 LCD with touch enabled with Raspberrypi3.
  Adding the makefile,</p>
