POWhy Is SDL_image not working

Body
copied!<p>I am new to C++ and SDL; I am trying to add a new SDL extension libary using instructions found here: <a href="http://www.lazyfoo.net/SDL_tutorials/lesson03/windows/devcpp/index.php" rel="nofollow">http://www.lazyfoo.net/SDL_tutorials/lesson03/windows/devcpp/index.php</a> </p> <p>But I get these errors:</p> <p>3 C:\Documents and Settings\Edmund\My Documents\C++\myprojects\SDL\SDLevent.cpp SDL/SDL_image.h: No such file or directory. </p> <p>C:\Documents and Settings\Edmund\My Documents\C++\myprojects\SDL\SDLevent.cpp In function `SDL_Surface* load_image(std::string)':</p> <p>28 C:\Documents and Settings\Edmund\My Documents\C++\myprojects\SDL\SDLevent.cpp `IMG_Load' undeclared (first use this function) </p> <p>and then a bunch of unqualified ids.</p> <p>This is my code:</p> <pre><code>#include "SDL/SDL.h" #include "SDL/SDL_image.h" #include <string> //Screen attributes const int SCREEN_WIDTH = 640; const int SCREEN_HEIGHT = 480; const int SCREEN_BPP = 32; //The surfaces SDL_Surface *image = NULL; SDL_Surface *screen = NULL; //The event structure that will be used SDL_Event event; SDL_Surface *load_image( std::string filename ) { //The image that's loaded SDL_Surface* loadedImage = NULL; //The optimized image that will be used SDL_Surface* optimizedImage = NULL; //Load the image loadedImage = IMG_Load( filename.c_str() ); //If the image loaded if( loadedImage != NULL ) { //Create an optimized image optimizedImage = SDL_DisplayFormat( loadedImage ); //Free the old image SDL_FreeSurface( loadedImage ); } //Return the optimized image return optimizedImage; } void apply_surface( int x, int y, SDL_Surface* source, SDL_Surface* destination ) { //Temporary rectangle to hold the offsets SDL_Rect offset; //Get the offsets offset.x = x; offset.y = y; //Blit the surface SDL_BlitSurface( source, NULL, destination, &offset ); } bool init() { //Initialize all SDL subsystems if( SDL_Init( SDL_INIT_EVERYTHING ) == -1 ) { return false; } //Set up the screen screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_SWSURFACE ); //If there was an error in setting up the screen if( screen == NULL ) { return false; } //Set the window caption SDL_WM_SetCaption( "Event test", NULL ); //If everything initialized fine return true; } bool load_files() { //Load the image image = load_image( "astyle.bmp" ); //If there was an error in loading the image if( image == NULL ) { return false; } //If everything loaded fine return true; } void clean_up() { //Free the image SDL_FreeSurface( image ); //Quit SDL SDL_Quit(); } //Initialize if( init() == false ) { return 1; } //Load the files if( load_files() == false ) { return 1; } //Apply the surface to the screen apply_surface( 0, 0, image, screen ); //Update the screen if( SDL_Flip( screen ) == -1 ) { return 1; } //While the user hasn't quit while( quit == false ) { //While there's an event to handle while( SDL_PollEvent( &event ) ) { //If the user has Xed out the window if( event.type == SDL_QUIT ) { //Quit the program quit = true; } } } //Free the surface and quit SDL clean_up(); return 0; } </code></pre> <p>It is pretty much identical to what is on the tutorial so it should not be a problem with the code. I have followed the Instructions on Lazy foo to the letter, I have put all of the files in the right place and linked to them so i do not know what I am doing wrong.</p>
