Hi all,

I'm trying to set up a development environment for Kernel development.
What have done is follows:

1. setarch linux32 make defconfig.
2.make oldconfig O=/mnt/build/linux
3.make menuconfig O=/mnt/build/linux
4.make.

After that i'm trying to boot the the new kernel in QEMU with GDB stub
as following:

$qemu -s -S /dev/zero -kernel /mnt/build/linux/arch/x86/boot/bzImage

Then i get the tcp port which qemu listens for an incoming gdb client :

$netstat -tap | grep qemu

Then i use gdb /mnt/build/linux/vmlinux to load the image. And set the
target to the remote port.

But when i get a connection, Qemu Starts to boot. But it complains
that the kernel needs a 64 bit Cpu.

But as i have configured it to be x86 it should not be the case.

Where i'm doing something wrong?

Cheers
