autoconf error

[Alexandre Carlos de Oliveira]

Hi, all

I was compiling iptables-1.2.4-0.2 and i expirienced the following error.
I'm using redhat 7.3, can someone help me? I downloaded the most recent
version of autoconf (2.57) , and the error continues, and i've looked for
an updated rpm file for the kernel-headers, but i didn't find anyone.

address@hidden iptables]# make

make: *** [extensions/libipt_tcp_sh.o] Error 1

I went to see what was written on the autoconf.h file and the were only
one line
#error Invalid kernel header included in user space

I would like to know if this is correct?

Regards
