Using netgraph in kernel modules

[Nomad Esst]

Hi

I included the two files in my kernel module :

#include <netgraph/netgraph.h>#include <netgraph/ng_message.h>

And here is contents of Makefile:

  KMOD= echo   SRCS= char_dev.c

  .include <bsd.kmod.mk>

When I try to run make I face the following errors:


@/netgraph/ng_message.h:59: error: expected specifier-qualifier-list before 'u_char'
@/netgraph/ng_message.h:227: error: expected specifier-qualifier-list before 'uint32_t'

Stop in /extra/char-dev.


What's the problem??
