&gt; Anna and I are trying to compile GRASS 7 on Mac OS 10.8. Although there<br>

&gt;<br>
&gt; But than we were not able to start GRASS because initialization ended with<br>
&gt; the error message about missing X Window system. This comes from<br>
&gt; init/grass.py where it checks for DISPLAY variable. The variable is not<br>
&gt; set. Do we need it to test it for GRASS7 and Mac OS? Setting to any value<br>
&gt; (e.g., export DISPLAY=0) solved the problem.<br>
<br>

<br>
      if os.getenv(&#39;DISPLAY&#39;) or windows:<br>
