Or reference the namespace explicitly (a`la Soprano::qHash).

Yes. We&#39;ve seen that problem. It happens because:<br>
<br>
&nbsp;* Soprano uses a namespace<br>
&nbsp;* Soprano defined qHash(Soprano::Node) before qhash.h was defined<br>
&nbsp;* qvariant.h has changed in 4.5, including qhash.h now<br>
<br>
That means the definition for QHash jumped above the definition of the<br>
qHash function. You have to put the function inside the Soprano namespace<br>
for this to work.<br>
<br>
According to our expert, this is the way the C++ name lookup rules say it<br>
should be.<br>
