I'm trying to use SOIL (Simple OpenGL Image Library) to load images in my project.  However, it is crashing whenever I call SOIL_load_image, from an unhandled exception writing location 0x00000014.  (I'm following this tutorial, btw: http://open.gl/textures).  

 

I'm unsure of what I can do to fix this issue, but I think its something related to how I'm setting up the library.  Yesterday, I was trying to do something similar with libPNG and was running into a similar crash when the library attempted to do some file IO.  At the time, I thought it was probably an issue with the library, but now that I'm getting another crash with a different library, I think it might be me.

 

For the SOIL library, I built the project and copied the debug SOIL.lib to my VC/lib directory, and SOIL.h to the VC/include directory.  It seems to be building fine, but is crashing.  I tried it with the release .lib as well and the same thing happens.

 

Where I'm trying to load the image (GLTextureFactory.cpp):

#include "GLTextureFactory.h"

#pragma comment(lib, "SOIL")

#include <SOIL.h>

#include "GLTexture.h"

GLTextureFactory::GLTextureFactory(void)
{

}

GLTextureFactory::~GLTextureFactory(void)
{

}

GLTexture *GLTextureFactory::createTextureForImage(const char *imageFilename)
{
    int width, height;

    //CRASHING ON THIS LINE
    unsigned char* image = SOIL_load_image(imageFilename, &width, &height, 0, SOIL_LOAD_RGB);
    
    //glTexImage2D( GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGB, GL_UNSIGNED_BYTE, image );

    return new GLTexture(0);
}

 

I have included GLM in my project, and am also linking against:
#pragma comment(lib, "GLFW")
#pragma comment(lib, "opengl32")
#pragma comment(lib, "glu32")
#pragma comment(lib, "glew32")
 
Any help is very appreciated!

Where is GLTextureFactory::createTextureForImage() being called?

Its getting called after my OpenGL context is created.  I don't think that's related to the problem, though, since I'm not actually doing anything OpenGL related in here. (yet).

Ah, I forgot to mention, I'm getting one build warning, but I'm not sure how to fix it, or if its even relevant:

1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library

It might be related. If filename is invalid, it could cause a crash. Try posting a minimal example that still exhibits the problem. If at any point after your remove something that isn't necessary and the problem goes away, investigate that.

Hmm, I was able to fix the issue.  Evidently the order and/or location of all the #pragma comment(lib, "lib") makes a difference.  I put them all together in a different file and all is well.  I tried putting them all in my main.cpp, but that didn't work.  Not sure why.  Thanks for the help.
