Title: LoadFromFile always fails
Post by: jerryd on April 20, 2013, 07:28:37 am: SFML forum,

SFML 1.6 Visual C++ Express 2010

I'm new to SFML and have a very simple "open a window" program
called FirstWindow that works.

Now I try to load an image with this code:
sf::Image MyImage;
MyImage.LoadFromFile("Sprite2.bmp");

It compiles without errors but when I run it I get this message:
"FirstWindow has encountered an error and must close".

If I comment out the LoadFromFile command the program runs OK.

The file Sprite2.bmp resides in the program folder and I
can open it and see the bmp image.

Any suggestions?

Thanks for the reply.

I'm following a tutorial at:
http://www.sfml-dev.org/tutorials/1.6/graphics-sprite.php

These totorials are for SFML 1.6 and Visual C++ 2010 Express
so I never loaded Visual Studio 2008. Also I don't know how
to compile SFML.

Can you give me some instructions?

I realized that I could get all the instructions I
needed on the net.

I went through the entire tutorial on compiling SFML at:
https://www.youtube.com/watch?v=-uHGZGgMETg
and got the sample program to work.

I changed all the properties in my FirstWindow solution but
got the same error message.

Here's my code:

#include <SFML/System.hpp>
#include <SFML/Graphics.hpp>

int main()
{
   // Render up a window called MyWindow
   sf::RenderWindow MyWindow(sf::VideoMode(800, 600, 16), "SFML Window");

   MyWindow.SetFramerateLimit(60); // Limit to 60 frames per second

   // load the image
   sf::Image MyImage;
   //MyImage.LoadFromFile("Sprite2.bmp");

   bool Running = true;
   while (Running)
   {
      // check if there are any events
      sf::Event MyEvent;
      while (MyWindow.GetEvent(MyEvent))
      {
         // Window closed by X
         if (MyEvent.Type == sf::Event::Closed) MyWindow.Close();

         // Escape key pressed
         if ((MyEvent.Type == sf::Event::KeyPressed) && (MyEvent.Key.Code == sf::Key::Escape))
MyWindow.Close();
      }

      // Clear the screen to black
   MyWindow.Clear(sf::Color(0, 0, 0));

      // display the window pointed to by MyWindow
      MyWindow.Display();
   }
   return EXIT_SUCCESS;
}

See anything wrong here?

Post by: Nexus on April 21, 2013, 02:32:30 pm: I recommend SFML 2, see here (https://github.com/SFML/SFML/wiki/FAQ#wiki-grl-version) for the reasons.

In fact, we should start a broad campaign on YouTube to deprecate all the SFML 1.6 tutorials ;)

Also, use the [code=cpp] [/code] tags to show C++ code.

Wanna go trolling for 2.0. ;D Sounds awesome.

Maybe someone who can write good could start here: http://en.wikipedia.org/wiki/SFML

Found the problem. I didn't have sfml-graphics-d.lib in the
Linker INPUTS.

I have downloaded and compiled SFML 2.0.
I made a solution similar to this one but when I click on the
"build" the compiler option is grayed out. If I type F5 I get
an error message that says:
"LINK : fatal error LNK1561: entry point must be defined"

What am I missing?
