[BusyBox] networking/udhcp/packet.c:122: error: storage sizeof `dest' isn't known

[Josh Goebel]

If I go back a version or two I get a similar (but not exactly the same)
error in socket.c... so I can tell that things have been changed... I
suppose I'm just imagining there is some little detail that's been
missed that is affecting me.

What type of problem would I look for with my headers?  I'm using
uclibc's buildroot, the latest release of uclibc and kernel 2.0.39... So
I have uclibc and the standard linux 2.0.39 headers.  Has anyone else
here successfully compiled with this combo?

udhcp underwent quite a few changes, but packet.c was barely touched.
According to my man pages, PF_PACKET to be used, the following includes
must be used:

#include <sys/socket.h>
#include <features.h>    /* for the glibc version number */
#if __GLIBC__ >= 2 && __GLIBC_MINOR__ >= 1
#include <netpacket/packet.h>
#include <net/ethernet.h>     /* the L2 protocols */
#else
#include <asm/types.h>
#include <linux/if_packet.h>
#include <linux/if_ether.h>   /* The L2 protocols */
#endif

packet.c has these includes. I think there is a problem with your
headers.
