I use codeblock and I tried many things to only show on the screen a sprite from a class. If I only use the main it works but I plan a bigger project so I need to be able to draw those sprites.
What I copy-paste here is the last try I did to make it work. The error is : undefined reference to Snake::Snake()' wich is my class
Theres nothing in the map.cpp for the moment so its not important.

#include "map.h"

#include <iostream>
#include <vector>
int main()
{
int h = 45;
int l = 45;
sf::RenderWindow App(sf::VideoMode(20*h, 20*l, 32), "Snake O Tron");
App.SetFramerateLimit(60);
Snake test;
std::vector<sf::Sprite> serpent;
std::vector<std::vector<int> > map(h, std::vector<int> (l,0));
// Start game loop
while (App.IsOpened())
{
// Process events
sf::Event Event;
while (App.GetEvent(Event))
{
// Close window : exit
if (Event.Type == sf::Event::Closed)
App.Close();
}
App.Clear();
for(int i = 0; i<serpent.size(); i++)
{
App.Draw(serpent[i]);
}
App.Display();
}
return EXIT_SUCCESS;
}
