Thanks, much appreciated

You can find more info about BOOST_JOIN error here:
https://bugreports.qt-project.org/browse/QTBUG-22829I successfully used the suggested workaround of wrapping has_binary_operator.hpp inside an #ifndef Q_MOC_RUN with boost 1.57.
When using current 1.9 miniupnpc sources make sure to define -DMINIUPNP_STATICLIB instead of -DSTATICLIB (v1.9 release still needs -DSTATICLIB).
Hope that helps
