boost::shared_ptr error

Question

class EntityHolder { public: EntityHolder ( ) { } EntityHolder ( const EntityHolder& other ) { } ~EntityHolder ( ) { } EntityHolder& operator = ( const EntityHolder& other ) { return *this; } // =

When I am trying to create boost:shared_ptr, I get the following error:

..\src\Entity.cpp:7:34: error: no matching function for call to 'boost::shared_ptr<orm::EntityHolder>::shared_ptr (orm::EntityHolder&)'

What does this mean?

You should post the line in which you're trying to make the shared_ptr, i.e. the line that gives the error. — Joseph Mansfield

Looks like you're trying to pass an object of type EntityHolder directly to the constructor of the shared_ptr, but you're supposed to give it a pointer, like so:

boost::shared_ptr<EntityHolder> p(new EntityHolder);
