I've tried compiling it using 2.6.18 and 2.6.20. Using gcc (GCC) 4.1.1 20070105 (Red Hat 4.1.1-51). A patch to iptables like this: --- kernel-2.6.20/linux-2.6.20/include/linux/netfilter_ipv4/ip_tables.h 2007-02-05 05:44:54.000000000 +1100 +++ kernel-2.6.20-skg/linux-2.6.20/include/linux/netfilter_ipv4/ip_tables.h 2007-07-31 14:22:41.000000000 +1000 @@ -16,7 +16,6 @@ #define _IPTABLES_H #ifdef __KERNEL__ -#include <linux/if.h> #include <linux/types.h> #include <linux/in.h> #include <linux/ip.h> @@ -24,7 +23,7 @@ #endif #include <linux/compiler.h> #include <linux/netfilter_ipv4.h> - +#include <linux/if.h> #include <linux/netfilter/x_tables.h> #define IPT_FUNCTION_MAXNAMELEN XT_FUNCTION_MAXNAMELEN allows me to compile the modules using -std=c99. The patch just includes the file that contains the missing macro definition that gcc was complaining about.
