SDL fails to load textures

So I was following this set of tutorials
http://lazyfoo.net/tutorials/SDL/index.php until I hit a dead end- SDL
didn't want to load textures. When I got to the part where you can load
textures, whenever I tried running the program, it instantly closes with no
console messages. Even though I copied the code here almost exactly
http://lazyfoo.net/tutorials/SDL/07_texture_loading_and_rendering/index.php
SDL still wanted to be disagreeable.

Any advice?
