Yes thanks Steven! The queue was modified inside a const method of the class. I corrected it but now I get these warning(we treat them as errors). These are the warnings,
1> priority_queue_example.cpp

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());
}
};
Can you please help with this? I understand that 'rhs' is unused, but in my implementation, it is used but the warning is pointing to boost code. I don't understand it.
