title: cannot convert from 'const char [3]' to 'char *' x100000 (Qt Creator C++ Windows 32)
body: <p>Everything was working fine just five minutes ago when I tapped f5 and got 102 errors:</p>
  
  <pre><code>error: C2440: 'initializing' : cannot convert from 'const char [17]' to 'char *'
  Conversion from string literal loses const qualifier (see /Zc:strictStrings)
  </code></pre>
  
  <p>That specific one is at line 30:</p>
  
  <pre><code>char* hexchars = "0123456789ABCDEF";
  </code></pre>
  
  <p>I haven't touched the file the errors are in for at least a week. I'd normally say I accidentally changed something in the compile args or something, but I haven't opened settings since much before it started erroring.</p>
  
  <p>Any ideas? I must have absentmindedly changed some setting but I really can't remember thinking "uh oh what did I just do?"</p>
