Hello everyone, I am trying to load an image into my program that is using SDL, OpenGL, and SDL_image to load images. But for some reason IMG_Load() always returns a null pointer, no matter what. Even SDL_LoadBMP() returns a null pointer. I have the DLLs and the images in with my executable. Here is a codeblock:

    SDL_Surface *test = IMG_Load("test.png");

    std::cout << "test=" << test << " Reason: " << SDL_GetError() << std::endl;

Here is it's output:

test=00000000 Reason: Couldn't open test.png

If I try to load test.bmp with SDL_LoadBMP() I get the same results, with the obvious change of png to bmp. I am sure the pictures are there. I am using Microsoft Visual C++ 2008 Express Here are my libraries that i have linked:

SDLmain.lib
SDL.lib
SDL_image.lib
opengl32.lib
glu32.lib
gdi32.lib

Here is part of my globals.h:

#include "SDL.h"
#include "SDL_main.h"
#include "SDL_image.h"
#include "SDL_opengl.h"
#include <gl.h>
#include <glu.h>
#include <glext.h>

I am running release mode because debug mode causes link errors with "__imp___CrtDbgReportW". What am i doing wrong? Thank you. [Edited by - Hacktank on December 26, 2009 7:18:57 PM]

I got debug mode to work, i was using the wrong runtime library. And yes, i set the working directory of debug mode to the folder the exe and other files are in, as well as release mode. Neither work.

I tried loading a text file in to see if the problem is global and it fails too.

    std::ifstream testfile("test.txt");    std::string line;    if(testfile.is_open()) while(!testfile.eof()) {	   	   std::getline(testfile,line);	   std::cout << line << std::endl;    } else std::cout << "File cannot be opened" << std::endl;

Thank you very much, both of you. I got it working, i had the active directory set to where all my source files were, not my exe, fail. Its strange tho, a static reference to the file wouldn't work either, no matter tho.
