Any idea whats wrong with my code? when i execute glCompressedTexImage2D() the program just crashes (comes the Windows XP crash message thing...) I'm trying to load DDS image without mipmaps, the image format is DDS DXT1. Am i missing some include file, or what did i do wrong? I downloaded the included files from: http://sourceforge.net/projects/glew/files/glew/1.5.1/glew-1.5.1-win32.zip/download I have glew32.dll in the same folder as my .exe is. The code below has only the parts i changed to be able to load DDS images:
#pragma comment(lib, "glew32.lib")
#include <GL\glew.h>
#include <GL\gl.h>
...
typedef struct {
GLuint dwSize;
GLuint dwFlags;
GLuint dwFourCC;
GLuint dwRGBBitCount;
GLuint dwRBitMask;
GLuint dwGBitMask;
GLuint dwBBitMask;
GLuint dwABitMask;
} DDS_PIXELFORMAT;
typedef struct {
GLuint dwMagic;
GLuint dwSize;
GLuint dwFlags;
GLuint dwHeight;
GLuint dwWidth;
GLuint dwLinearSize;

GLuint dwCaps;
GLuint dwCaps2;
GLuint dwCaps3;
GLuint dwCaps4;
GLuint dwReserved2;
} DDS_HEADER;
DDS_HEADER DDS_headers;
...
FILE *fp = fopen("test.dds", "rb");
fread(&DDS_headers, 1, sizeof(DDS_headers), fp);
img_width = DDS_headers.dwWidth;
img_height = DDS_headers.dwHeight;
maxsize = (img_width*img_height)/2;
unsigned char *imgdata = (unsigned char *)malloc(maxsize);
fread(imgdata, 1, maxsize, fp);
fclose(fp);
GLuint texID;
glGenTextures(1, &texID);
glBindTexture(GL_TEXTURE_2D, texID);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glCompressedTexImage2D(GL_TEXTURE_2D, 0, GL_PALETTE4_R5_G6_B5_OES, img_width, img_height, 0, maxsize, imgdata);
