Thanks, turns out I needed to include sys/sysctl.h.

Now that's sorted I am still left with one last issue, which seem
to be related:

undefined reference to `udpstat'
undefined reference to `udb'

They are both defined in the header 'udp_var.h' and from what I
can gather their implementation is in:

   net\bsd_tcpip\v2_0_51\src\sys\netinet\udb_usrreq.h

and when I do an 'nm' in libtarget.h I see:

   net_bsd_tcpip_udp_usrreq.o

Our eCos Config project definetly has the FreeBSD stack selected.
I am a little confused. Any ideas?

Andre

Take a look at sys/param.h

So thats your problem then. Find out why.

It doesn't look like it. Here is the what I see when I look at
UdpMib.o:

#define UDPCTL_CHECKSUM 1
#define UDPCTL_STATS 2
#define UDPCTL_MAXDGRAM 3
#define UDPCTL_RECVSPACE 4
#define UDPCTL_PCBLIST 5
#define UDPCTL_MAXID 6

#define UDPCTL_NAMES { { 0, 0 }, { "checksum", CTLTYPE_INT }, { "stats", CTLTYPE_STRUCT }, { "maxdgram", CTLTYPE_INT }, { "recvspace", CTLTYPE_INT }, { "pcblist", CTLTYPE_STRUCT } }
# 117 "C:/VWLocation/EZ-SC_SW_1.0_DEV_ALL/ez_ne/sc_cc/build/sc-application_install/include/netinet/udp_var.h"
SYSCTL_DECL(_net_inet_udp);

extern struct pr_usrreqs udp_usrreqs;
extern struct inpcbhead udb;
extern struct inpcbinfo udbinfo;
extern u_long udp_sendspace;
extern u_long udp_recvspace;
extern struct udpstat udpstat;
extern int log_in_vain;

void udp_ctlinput (int, struct sockaddr *, void *);
void udp_init (void);
void udp_input (struct mbuf *, int);

void udp_notify (struct inpcb *inp, int _errno);
int udp_shutdown (struct socket *so);
# 29 "../interface/snmp/src/UdpMib.cpp" 2


}
