title: Where to get Sudoku generator in C++?
body: <p>Here is one - <a href="http://ostermiller.org/qqwing/" rel="nofollow noreferrer">http://ostermiller.org/qqwing/</a>
  But sometimes my PHP code (shell_exec('qqwing..')) dies and in syslog I can find segfault errors for qqwing.</p>
  
  <p>So, I'm searching for better generator, but can't find one. Fast and with difficulty levels.</p>
  
  <p>Any suggestions?</p>
