 <p>The problem is that the <code>SOUNDEX</code> algorithm is disabled by default and you have to use the compiler flag <code>-DSQLITE_SOUNDEX=1</code> when building <a href="http://www.sqlite.org/compile.html#soundex" rel="nofollow"><code>sqlite</code></a>. </p> <p>So you have to build the <code>sqlite</code> driver with this flag on, and then build the plugin by linking it to your <a href="http://lists.trolltech.com/qt4-preview-feedback/2005-05/thread01021-0.html" rel="nofollow"><code>sqlite</code> build</a>.</p>
