LD_PRELOAD cannot be preloaded

[M4rc0]

Hi,

I have a Fedora 11 x86_64 bit.
And I'm trying to run a bind_hack with wine through LD_PRELOAD and it's giving me:

ERROR: ld.so: object '/tmp/bind_hack.so' from LD_PRELOAD cannot be preloaded: ignored.

This is the hack:

/* This file is ditributed under the GPLv2 */

#define _GNU_SOURCE

#include </usr/include/sys/socket.h>
#include </usr/include/sys/types.h>
#include </usr/include/netinet/in.h>
#include </usr/include/dlfcn.h>
#include </usr/include/string.h>

int (*real_bind)(int fd, const struct sockaddr* add, socklen_t len);

void _init(void) {
    real_bind = dlsym(RTLD_NEXT, "bind");
}

int bind(int fd, const struct sockaddr* addr, socklen_t len) {
    struct sockaddr_in* sa;

    if(addr->sa_family==AF_INET) {
        sa = (struct sockaddr_in*) addr;
        memset(&sa->sin_addr, 0, sizeof(sa->sin_addr));
    }
    return real_bind(fd, addr, len);
}

And this is how I'm compiling:

$ cc bind_hack.c -o bind_hack.so -O2 -fPIC -Wall -shared -lc -nostdlib -m32

For this error to happen, I believe it's trying to load the 64 bits libs somehow? when it should be loading the 32 bit.

Is there any problem with the code? Perhaps if I compile in a 32bit machine it will work?

Any suggestions?
