Hi,

When I try to build "priority_queue_example.cpp" it get these warnings(and so errors) pointing to  "priority_queue_example.h" on the line where my priority_queue is declared. The warnings are,

1>  priority_queue_example.cpp

1>c:\Projects\lib\boost\boost\heap\detail\stable_heap.hpp(102): error C2220: warning treated as error - no 'object' file generated

1>c:\Projects\lib\boost\boost\heap\detail\stable_heap.hpp(102): warning C4100: 'rhs' : unreferenced formal parameter

My priority_queue is declared as,

mutable boost::heap::priority_queue<myObject*, boost::heap::compare<myObjectPtrCompare> > hp;

Can you please help me fix this, I have been trying to for 2 days. Not sure what this means.

This is my comparison class defined,

struct myObjectPtrCompare

{

bool operator()(const myObject* lhs, const myObject* rhs) const

{

return (lhs->getProp() < rhs->getProp());

}

};

 

Thanks!
