Hello,
I'm trying to update my resourceManager to use boost::shared_ptrs, but have hit a hole in my knowledge!
When I normally allocate a shared_ptr elsewhere, I do so like this:
boost::shared_ptr<CMyObject> obj(new CMyObject);
using a default constructor. works fine.
In my resource manager, which is a template, I get confused. Here's what I am trying:
The type is a cTexture whose constructor looks like this:
cTexture( std::string name, std::string path = "data\\shaders\\" );
The compiler complains on the line:
boost::shared_ptr<Type> resource(new Type( name, path ));
Saying:
I don't understand why the template type is shared_ptr<cTexture>, not cTexture.
Why can't it see the cTexture constructor?
Thanks in advance.

boost::shared_ptr<Type> Add( std::string name, std::string path = "" )
{
// If the element already exists, then return a pointer to it.
boost::shared_ptr<Type> element = GetElement( name );
if( element != NULL )
{
g_log->SIM( "Resource already in use: %s\n", const_cast<char*>(name.c_str()) );
return element;
}
// Create the resource
boost::shared_ptr<Type> resource(new Type( name, path ));
g_log->SIM( "New resource required: %s\n", const_cast<char*>(name.c_str()) );
// Add the new resource to the manager and return a pointer to it.
return *(m_list->Add( &resource ));
}

Where is the call to the Add() function which causes this error? What is the type parameter of the manager that you instantiated?
