Problem loading texture in PSPGL. Simple answer most likely

[sg57]

Code: Select all

Width of Textures/Floor.bmp: 128
                                                   Height of Textures/Floor.bmp:
 128
    Width of Textures/Sky.bmp: 128
                                  Height of Textures/Sky.bmp: 128
                                                                 Exception - Add

That is PSPLink, and after doing the psp-addr2line im getting this:

Code: Select all

$ psp-addr2line -fe blah.elf 0x08912BE4
memcpy
../../../../../../newlib/libc/machine/mips/memcpy.c:146
$ psp-addr2line -fe blah.elf 0x08911548
fread
../../../../../newlib/libc/stdio/fread.c:210

My BMP Loading function is this:

Code: Select all

int LoadBMP(char *filename, Image *image) {
    FILE *file;
    unsigned long size;                 // size of the image in bytes.
    unsigned long i;                    // standard counter.
    unsigned short int planes;          // number of planes in image (must be 1) 
    unsigned short int bpp;             // number of bits per pixel (must be 24)
    char temp;                          // used to convert bgr to rgb color.

    // make sure the file is there.
    if ((file = fopen(filename, "rb"))==NULL)
    {
	printf("File Not Found : %s\n",filename);
	return 0;
    }
    
    // seek through the bmp header, up to the width/height:
    fseek(file, 18, SEEK_CUR);

    // read the width
    if ((i = fread(&image->sizeX, 4, 1, file)) != 1) {
	printf("Error reading width from %s.\n", filename);
	return 0;
    }
    printf("Width of %s: %lu\n", filename, image->sizeX);
    
    // read the height 
    if ((i = fread(&image->sizeY, 4, 1, file)) != 1) {
	printf("Error reading height from %s.\n", filename);
	return 0;
    }
    printf("Height of %s: %lu\n", filename, image->sizeY);
    
    // calculate the size (assuming 24 bits or 3 bytes per pixel).
    size = image->sizeX * image->sizeY * 3;

    // read the planes
    if ((fread(&planes, 2, 1, file)) != 1) {
	printf("Error reading planes from %s.\n", filename);
	return 0;
    }
    if (planes != 1) {
	printf("Planes from %s is not 1: %u\n", filename, planes);
	return 0;
    }

    // read the bpp
    if ((i = fread(&bpp, 2, 1, file)) != 1) {
	printf("Error reading bpp from %s.\n", filename);
	return 0;
    }
    if (bpp != 24) {
	printf("Bpp from %s is not 24: %u\n", filename, bpp);
	return 0;
    }
	
    // seek past the rest of the bitmap header.
    fseek(file, 24, SEEK_CUR);

    // read the data. 
    image->data = (char *) malloc(size);
    if (image->data == NULL) {
	printf("Error allocating memory for color-corrected image data");
	return 0;	
    }

    if ((i = fread(image->data, size, 1, file)) != 1) {
	printf("Error reading image data from %s.\n", filename);
	return 0;
    }

    for &#40;i=0;i<size;i+=3&#41; &#123; // reverse all of the colors. &#40;bgr -> rgb&#41;
	temp = image->data&#91;i&#93;;
	image->data&#91;i&#93; = image->data&#91;i+2&#93;;
	image->data&#91;i+2&#93; = temp;
    &#125;

    // we're done.
    return 1;
&#125;

Of course taken from the tutorials :P

I dont see how the exception could be in something i never even touched... But it did say fread and i did use fread in my LoadBMP so its somtehing in there... Im trying to load 5 textures, and its onlyloading the sky and floor...

Any suggestions?

Looks like 'image' is either null or not pointing at memory you own.
