Here's the error when i try to compile the mac wallet (cd olympiccoin/ && qmake *.pro && make;)
src/qt/macdockiconhandler.mm:50:39: error: assigning to 'objc_object *' from
incompatible type 'DockIconClickEventHandler *'
...= [[DockIconClickEventHandler alloc] initWithDockIconHandler:this];
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
src/qt/macdockiconhandler.mm:60:6: warning: receiver type 'objc_object *' is not
'id' or interface pointer, consider casting it to 'id' [-Wreceiver-expr]
[this->m_dockIconClickEventHandler release];
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
then it stops compiling.
