Ah, wow.

So it was a bug on my side, now it works!

OTOH, there is an other odd error. Here is a sample test program:

#include <stdio.h>
#include <sys/stat.h>

int main()
{
        struct stat buf;
        if (stat("usr/bin/ls", &buf)) {
                printf("not found\n");
        } else {
                printf("found\n");
        }
        return 0;
}

host$ ppc-frugalware-linux-gcc hello2.c -o hello2
host$ file hello2
hello2: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1
(SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.4.3, not
stripped
host$ ./hello2
found
host$ sudo chroot .
chroot:/# ./hello2
not found
chroot:/# grep usr hello2.c
        if (stat("usr/bin/ls", &buf)) {
chroot:/# ls usr/bin/ls
usr/bin/ls

Is it a bug that stat() does not found what ls does, or have I missed
something? :)

Thanks.

PS: Just in case somebody wants to play with it, here is the PPC chroot
tarball I'm using:
