Could you paste output of pkg-config --cflags xtables|od -x pls?

[root@maticni-gate ipt-netflow-2.2]# pkg-config --cflags xtables|od -x

Thanks. Could you also show output of:

$ ls -l /usr/include/xtables.h
$ echo -e '#define __EXPORTED_HEADERS__\n#include <xtables.h>\n' > test.c
$ gcc -c test.c

[jura22]

Good job. Its my fault. Missing gcc. Please insert in to README first step for CentOS/RHEL:
yum group install "Development Tools"
Thanks
