Error displaying OpenGL texture

Question

Here is the BIG problem with my project:

I like the tutorials on the NeHe website, and Windows XP does a great job with programs. However, when I reformatted my computer, changed the OS to Windows Vista and reinstalled my Dev-C ++ compiler, and then I tried to open any C ++ program that used textures, the program crashed.

I realized that my glaux.h was missing. I found the file on the Internet and recompiled my project, but it still crashed. Everything went well when I excluded the texture features.

Where is the problem and what can I do to solve it?

I thought one of them was the culprit: Windows Vista, my graphics card, glaux.h and libraries (I know it's listening), OpenGL.

.

Update: I have identified the source of the problem.

This piece of code caused my program to crash:

if (TextureImage[0]) {
    if (TextureImage[0]->data) {    
    free(TextureImage[0]->data);
    }
    free(TextureImage[0]);
}

For some reason, my program is always reset whenever I order it to free up memory. When I commented on this section, my program works fine, except that all the colors have darkened (I think about it because of the colors of my raster file). Any tips?

Well, this was from the NeHe6 lesson, which worked great when I was still using Windows XP. Nothing really changed when I switched to Windows Vista.

Just so you know, here is the whole function:

#define NoOfTextures 3
GLuint  texture[NoOfTextures];

int LoadGLTextures()
{
    int Status=FALSE;

    AUX_RGBImageRec *TextureImage[NoOfTextures];

    memset(TextureImage,0,sizeof(void *)*1);

    if (TextureImage[0]=LoadBMP("Data/Bitmaps/texture.bmp"))
    {
        Status=TRUE;

        glGenTextures(1, &texture[0]);

        glBindTexture(GL_TEXTURE_2D, texture[0]);
        glTexImage2D(GL_TEXTURE_2D, 0, 3, TextureImage[0]->sizeX, TextureImage[0]->sizeY, 0, GL_RGB, GL_UNSIGNED_BYTE, TextureImage[0]->data);
        glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
        glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);

        if (TextureImage[0] != NULL) {  
            if (TextureImage[0]->data != NULL) {    
                free(TextureImage[0]->data);
            }
            free(TextureImage[0]);  
        }
    }

    return Status;                                      
}

.

Additional Information:

I often rebuild my project, and LoadBMP () is part of the same header file. This is the function LoadBMP ():

AUX_RGBImageRec *LoadBMP(char *Filename)
{
    FILE *File=NULL;

    if (!Filename)
    {
        return NULL;
    }

    File=fopen(Filename,"r");

    if (File)
    {
        fclose(File);
        return auxDIBImageLoad(Filename);
    }

    return NULL;
}

I think this is pretty clear.

Answer 4

Is the allocated memory (with malloc) in a library that you do not recompile, and then free the code just compiled? Different compiler / OS combinations use a bunch differently, so inconsistent malloc / free between two libraries compiled in different circumstances can cause a crash (or some other UB).

In particular, are you sure that you are compiling the implementation of LoadBMP () from the moment of reinstallation?
