SDL error in code

[Kristiano 96]

im having some trouble with SDL, this is the tutorial from lazyfoo , im using code blocks and when compile this code I get this: ld.exe: cannot find -lSDLmain
can someone please tell me whats the problem here??

//The headers
#include "SDL.h"
#include <string>

//The attributes of the screen
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;
const int SCREEN_BPP = 32;

//The surfaces that will be used
SDL_Surface *message = NULL;
SDL_Surface *background = NULL;
SDL_Surface *screen = NULL;

SDL_Surface *load_image( std::string filename )
{
    //Temporary storage for the image that's loaded
    SDL_Surface* loadedImage = NULL;

    //The optimized image that will be used
    SDL_Surface* optimizedImage = NULL;

    //Load the image
    loadedImage = SDL_LoadBMP( filename.c_str() );

    //If nothing went wrong in loading the image
    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 )
{
    //Make a temporary rectangle to hold the offsets
    SDL_Rect offset;

    //Give the offsets to the rectangle
    offset.x = x;
    offset.y = y;

    //Blit the surface
    SDL_BlitSurface( source, NULL, destination, &offset );
}

int main( int argc, char* args[] )
{
    //Initialize all SDL subsystems
    if( SDL_Init( SDL_INIT_EVERYTHING ) == -1 )
    {
        return 1;
    }

    //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 1;
    }

    //Set the window caption
    SDL_WM_SetCaption( "Hello World", NULL );

    //Load the images
    message = load_image( "hello.bmp" );
    background = load_image( "background.bmp" );

    //Apply the background to the screen
    apply_surface( 0, 0, background, screen );
    apply_surface( 320, 0, background, screen );
    apply_surface( 0, 240, background, screen );
    apply_surface( 320, 240, background, screen );

    //Apply the message to the screen
    apply_surface( 180, 140, message, screen );

    //Update the screen
    if( SDL_Flip( screen ) == -1 )
    {
        return 1;
    }

    //Wait 2 seconds
    SDL_Delay( 2000 );

    //Free the surfaces
    SDL_FreeSurface( message );
    SDL_FreeSurface( background );

    //Quit SDL
    SDL_Quit();

    return 0;
}

personally i dont know, but if certain other members see this they will tell you not to use sdl 1.* fyi. as for your errors, did you copy the dlls to the folder where your exe is?

[Kristiano 96]

only SDL.dll file. should I use 2.x versions of SDL??and is there some tutorials or books for SDL 2??

[Peter87]

You can use whatever version you want. SDL 2 is very new so there might be less information about it and it's less stable than SDL 1.2 that has been around for ages.

Not sure exactly what the problem is but you need more than just the .dll file. Make sure the linker finds the files in the lib folder.

yeah i didnt mean dont use it. i personally use it, but i know there are people here (i think disch may be one) who say use 2.0 as it uses/teaches bad programming. i havent done any research so i dont know, im just informing of another perspective
