Thread: object array problems (some openGL but its pretty irrelevant to the problem)

I have this project im working on. It will eventually be an implementation of Dijkstra's shortest path algorithm using some c++ classes and openGL to visualize it.

My problem is creating a data structure to hold an array of nodes that I can draw to the screen. Im sure there is something im missing, ive researched online for hours but I couldnt find anything that could help me with my problem. Here is the code thats giving me problems:

Node is declared in a header file. Ill go ahead and include that whole file.
"Node.h":

Code:

#include <GL/glut.h>
#include <GL/glu.h>
#include <GL/gl.h>

class Node {
	private: 
		GLfloat x, y, z;
		int numLinks;
		Node *links[];
	public: 
		//Node(GLfloat x, GLfloat y, ...);
		Node();
		Node(GLfloat x, GLfloat y);
		~Node();
		GLfloat getNodeX();
		GLfloat getNodeY();
		GLfloat getNodeZ() {return 0.0f;}
		GLvoid setNodeX(GLfloat x);
		GLvoid setNodeY(GLfloat y);
} Node;

Node::Node() {
	this->x = 0.0f;
	this->y = 0.0f;
	this->z = 0.0f;
}

Node::Node(GLfloat x, GLfloat y) {
	this->x = x;
	this->y = y;
	this->z = 0.0f;	
}

/*Node::Node(GLfloat x, GLfloat y, int numLinks, ...) {
	va_list arguments;
	va_start(arguments, numLinks);
	for (int i = 0; i < numLinks; i++) {
		this.links[i] = va_arg(arguments, *Node);
	}
	this.x = x;
	this.y = y;
	this.z = 0.0f;	
}*/

GLfloat Node::getNodeX() {
	return this->x;
}

GLfloat Node::getNodeY() {
	return this->y;
}

GLvoid Node::setNodeX(GLfloat x) {
	this->x = x;
}

GLvoid Node::setNodeY(GLfloat y) {
	this->y = y;
}

Node::~Node() {
}

Global array:

Code:

Node *nodes[NUM_NODES];

Code:

int makeNodes() {
	nodes[0] = new Node(0.0f, 0.0f);
}

g++ gives me these errors which correspond to the 4 lines above. The first error being the global variable.
DijkstraShortestPath.cpp:11:1: error: ‘Node’ does not name a type
DijkstraShortestPath.cpp: In function ‘int makeNodes()’:
DijkstraShortestPath.cpp:58:2: error: ‘nodes’ was not declared in this scope
DijkstraShortestPath.cpp:58:17: error: expected type-specifier before ‘Node’
DijkstraShortestPath.cpp:58:17: error: expected ‘;’ before ‘Node’

I would appreciate some suggestions on how to fix this, or even suggestions on a better way to keep track of my nodes.
