Hi!
I have a compile problem with iptables 1.2.8:
[...]
make -j 1 BINDIR=/usr/bin LIBDIR=/usr/lib MANDIR=/usr/man KERNEL_DIR=/lib/modules/2.4.21-xss/build/
Making dependencies: please wait...
Extensions found: IPv6:ah IPv6:esp IPv6:frag IPv6:ipv6header IPv6:hbh IPv6:dst IPv6:rt
cc -O2 -Wall -Wunused -I/lib/modules/2.4.21-xss/build//include -Iinclude/ -DIPTABLES_VERSION=\"1.2.8\" -fPIC -o extensions/libipt_ah_sh.o -c extensions/libipt_ah.c
ld -shared -o extensions/libipt_ah.so extensions/libipt_ah_sh.o

from /lib/modules/2.4.21-xss/build/include/linux/netfilter_ipv4/ip_conntrack.h:9,
from extensions/libipt_conntrack.c:12:
/lib/modules/2.4.21-xss/build/include/asm/bitops.h:410: conflicting types for `__ffs'
/usr/include/string.h:247: previous declaration of `__ffs'
make: *** [extensions/libipt_conntrack_sh.o] Error 1
[...]
Headers under "/usr/include/" come from glibc-2.1.3
"/lib/modules/2.4.21-xss/build/" is a symlink pointing to
linux-2.4.21 kernel sources (with ac4 patches)
Linux 2.4 and glibc-2.1.3 seem to have a different understanding
about __ffs(). Both use their own one...
Usually, this is not a problem, as userspace programs
don't include kernel headers, but iptables does.
I checked the mailing lists for glibc, linux-kernel and
iptables for solutions, but couldn't find any.
Any idea anyone?
