The flags are not meant to fix the problem; they are meant to
replicate it without having to install CentOS 5.

The problem is a bug that needs to be fixed from code.

if I added "-Os" option to CFLAGS then compiled. But issue not fixed.

make CFLAGS="-m32 -Os

LDFLAGS="-m32"

(Just to clarify: -m32 needs to be added to the userpace tools
compilation, not to the kernel modules')

Replicated in a fully 64-bit system by simply adding -m32 to both
CFLAGS and LDFLAGS. (`make CFLAGS=-m32 LDFLAGS=-m32`)
This is a bug. I'd be thankful if you could submit it to the issue tracker.
Regardless, I will be patching it right now. In a few hours I should
have an estimate on how long it's going to take.

I'd say the most likely cause is the 32-bit OS on top of the 64-bit
kernel. I mean I know we're supposed to support it, but I left it out
of the tests because I already had too much on my plate, and then
forgot about it. You're the first person attempting this as far as I
know.

I'll try to replicate it. BRB.

Hi
I builded jool in my old system without dkms. but I have some issues

1- instance name beginning "??" characters
2- instance looking netfilter but I wrote iptables.
3- When I execute the iptables command with jool, iptables returning
error. There is not any error message at dimesg.

jool kernel modules are builded 64bit arch with my custom kernel.(attached)
I builded jool userspace tools 32bit arch like my iptables tools.(I
can't attach because too big for mail size.)
I patched(attached) for build problem. I don't know those patches are
correct.

I know this is complicated. But I must be run in this system.

Are there any suggestions for me?
