Graphics / [help] Blank terminal window running latest SFML & minGW

SFML 1.6 doesn't work on Windows with ATI drivers. Use either the static version of SFML, or SFML 2.

How do I setup static SFML? Could I get a link?

Graphics / [help] Blank terminal window running latest SFML & minGW
« on: November 26, 2011, 11:42:35 am »
I have Code::Blocks 10.5 and SFML 1.6. I am making a simple program that gets 3 points from the user and prints out a triangle and the area as well as a few other things to the screen. Every time I run it, all I get is a blank terminal window.
Here is my code:
Code: [Select]
#include <iostream>
#include <math.h>
#include <sstream>
#include <SFML/Graphics.hpp>

using namespace std;

class triangle
{
    void sort();
public:
    triangle(int x1, int y1, int x2, int y2, int x3, int y3)
    {
        x[0] = x1;
        x[1] = x2;
        x[2] = x3;
        y[0] = y1;
        y[1] = y2;
        y[2] = y3;

        /////////
        //sides//
        /////////

        for (int i = 0; i < 3; i++)
        {
            if (i < 2)
            {
                side[i] = sqrt(((x[i + 1] - x[i]) * (x[i + 1] - x[i])) + ((y[i + 1] - y[i]) * (y[i + 1] - y[i])));
            }else
            {
                side[i] = sqrt(((x[0] - x[i]) * (x[0] - x[i])) + ((y[0] - y[i]) * (y[0] - y[i])));
            }
        }

        ////////
        //area//
        ////////

        float s;
        for (int i = 0; i < 3; i++)
        {
            if (side[i] < 0)
            {
                side[i] = -side[i];
            }
        }
        s = (side[0] + side[1] + side[2]) / 2;
        area = sqrt(s * (s - side[0]) * (s - side[1]) * (s - side[2]));

        /////////////////////
        //angles (oh, god.)//

        sort();
        float tempo = 0;
        float temop2 = 0;
        tempo = ((side[0] * side[0]) + (side[1] * side[1]) - (side[2] * side[2])) / (2 * side[0] * side[1]);
        tempo = acos(tempo);
        angle[0] = tempo * (180 / M_PI);
        temop2 = sin(tempo);
        tempo = (side[0] * temop2) / side[2];
        temop2 = asin(tempo);
        angle[1] = temop2 * (180 / M_PI);
        angle[2] = 180 - (angle[0] + angle[1]);
        for (int i = 0; i < 3; i++)
        {
            if (angle[i] == 90)
            {
                right = true;
            }
        }//0 sin 2  base = 3

        //////////////////////////////////////////////

        App.Draw(sf::Shape::Line(tri.x[0]/* x1 */, tri.y[0]/* y1 */, tri.x[1]/* x2 */, tri.y[1]/* y2 */, 3, sf::Color::White, 0, sf::Color::Black));
        App.Draw(sf::Shape::Line(tri.x[1]/* x2 */, tri.y[1]/* y2 */, tri.x[2]/* x3 */, tri.y[2]/* y3 */, 3, sf::Color::White, 0, sf::Color::Black));

        App.Draw(A);
        App.Draw(B);
        App.Draw(C);
        App.Display();
    }
    return EXIT_SUCCESS;
}

I have tried this on another computer with the same versions of Code::Blocks and SFML, and it worked. Why doesn't it work on my computer? No error msgs at all.
