Subject: [Qemu-devel] qemu on Fedora Core 3 (Linux 2.6.9+), glibc-2.3.3
Date: Sat, 18 Dec 2004 21:11:00 -0800 [thread overview]
Message-ID: <41C50D64.7070209@BitWagon.com> (raw)
In order to run qemu-snapshot-2004-12-17_23.tar.bz2 on:
Fedora Core 3 kernel-2.6.8-1.681_FC3 i686
gcc (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
glibc-2.3.3
binutils-2.15.92.0.2-5
I had to use the extra file and patch below.
Otherwise I got very early SIGSEGVs.
-----__restore.S [append __restore.o to VL_OBJS in i386/Makefile]
#include <asm/unistd.h>
__restore: .globl __restore
pop %eax
movl $ __NR_sigreturn,%eax
int $0x80
__restore_rt: .globl __restore_rt
movl $ __NR_rt_sigreturn,%eax
int $0x80
