C and SDL: A weird SDL_LoadBMP error

Hi,

I'm just getting started with using SDL to create graphics. I am using C. But I have come across an error which I simply cannot understand.

My code is supposed to set up SDL and then set a video mode. It does this successfully. However, it will not load a BMP file. I have tried putting the BMP file in the same directory and on the root of the drive in case something silly was happening, neither was successful.

Heres the code:

Code:

---

#include <SDL/SDL.h>#include <stdio.h>
#include <stdlib.h>




int main(int argc, char *argv[]){


    SDL_Surface *screen;
    SDL_Surface *image;
    SDL_Rect    src, dest;


    if(SDL_Init(SDL_INIT_VIDEO)!=0){
        return 1;
    }


    atexit(SDL_Quit);


    screen=SDL_SetVideoMode(640, 480, 16, SDL_FULLSCREEN);
    if(screen == NULL){
        return 2;
    }
    //SDL_Delay(2000);


    image=SDL_LoadBMP("image.bmp");
    if(image == NULL){
        return 3;
    }


    return 0;
}

---

It will _always_ return 3. It's like the file somehow does not exist.

Any help would be appreciated,
Thanks!


EDIT: Now this is getting really silly, even if I remove the "return 3" code and delete the EXE and then recompile, it is still returning 3 in the newly built EXE.

Two possibilities:
*) The compiler's programmer tried to pull out a really bad joke
*) The program is run from a temporary folder as backup or something

What compiler are you using?

Thanks for the reply.

I'm using Mingw32. I've looked around at several SDL tutorials and all of them load bitmaps in this way, so I'm puzzled.

As for the IDE, I'm using Code::Blocks. However, I'm considering moving to another IDE, as I still can't solve the mystery of why it is somehow either recompiling old code, or somehow resurrecting deleted EXE's.

OK, I have a "possible" solution.

The program never returns 3 with the following code, and the old EXE doesn't appear to come back from no where. I have never seen anything so stupid before, as far as I'm aware specifying just a file without a path means it will look in the same directory for the file, but apparently this is not the case with SDL. Can anyone explain this?

By using: image=SDL_LoadBMP("\\image.bmp"); instead of image=SDL_LoadBMP("image.bmp");

Scratch that, using \\ instead of just the file name means it will look on the root of the drive for the file, which obviously isn't a very good solution.

You could try printing the result of calling getcwd() / getwd() to show where the process starts looking for filenames.

If you're running the program within the IDE, then it might be the project root directory.

Code::Blocks has the annoying habit of NOT saving the project files when you press build. As a result, the old code is being compiled. Always press "Save All" before building.
