dynamic allocation of nodes

[John87Connor]

hi all,

i want to create a tree-like structure, made up of connected nodes. each node has a mother and a father node, and possibly everal children. all nodes should be allocated dynamically. the problem then becomes the first "root" node.

my solution (which doesn work):
typedef std::shared_ptr<Node> NodeRef;
in the PRIVATE constructor, i check if a NodeRef m_root exists, if not then create one via:
m_root = NodeRef(new Node(args));
that doesnt work, it has something to do with memory (<xmemory> new bla bla i dont really understand)
to create a new node, i want to call a static member "Create" which creates a new node, and makes sure that it is connected to the tree. in case one parent doesnt exist, it will be "root" by default.

any suggestions ?
do i have to make a "Initialize()" + "CleanUp()" call before / after using the node tree ?

by the way:
if i create a shared_ptr<Node>(&m_root), and m_root is created as global variable in .cpp file, the program creashed at the end (maybe because "delete" is called on the address ?)


thanks for any advice !

... ¿how's that a tree? explain your structure

> that doesnt work
your description is awful, leaving too many holes
¿why don't simply post the code?

post the error message verbatim.

¿you will only have one single "tree"?
¿does that limitation provide any benefit?
