Hello,
I recently found a mailing list post:
http://osdir.com/ml/emulators.qemu/2004-02/msg00162.html
That's exactly what I'm trying to set up.
I have a ppc chroot on an x86 machine - both Linux, with nptl-enabled
glibc.
I'm trying to run the following test app:
#include <stdio.h>
#include <unistd.h>
int main()
{
int pid;
pid = fork();
printf("child is %d\n", pid);
if (pid == -1)
perror("fork() failed");
return 0;
}
When I link this statically to a linuxthreads-enabled libc on ppc, then
I can run this using qemu-ppc without any problem:
$ sudo chroot . /qemu-ppc /hello-static
child is 0
child is 29207
However, when I link it dynamically (so it will use the nptl-enabled
libc from the chroot), I get:
$ sudo chroot . /qemu-ppc /hello
child is -1
fork() failed: Invalid argument
and yes, I just checked, when I run the same dynamic executable on a
real ppc, it works just fine, so I think this is a bug in qemu.
I tried qemu-0.9.1 and svn trunk, with the same results.
Is this a known issue?
Thanks!
