freebsd kernel 'make' failed : "undefined reference to..."

[Jamie Ann P. Zamodio]

Help!

I'm a UNIX newbie trying to compile a custom kernel
with modifications for TCP purposes. My system is
FreeBSD 4.3 running on i386. My 'make depend' works
fine, but when I geto to 'make', the following error
occurs:

tcp_usrreq.o: In function 'tcp6_connect':
/usr/src/sys/compile/MYKERNEL/../../netinet/tcp_usrreq.c(text+0xfa5):
undefined reference to 'tcpstat'

The error repeats for other tcp*.o files, like
tcp_output.o, tcp_subr.o, tcp_timer.o, and even
in6_proto.o. There are undefined references to
'tcp_mssopt', 'tcp_delack_enabled', 'tcp_ccgen',
'tcb', 'tcbinfo', 'M_TSEGQ', 'tcp_mss', and
'tcp6_input'. Most are common to the tcp*.o files.

What should I do?? Googling gives me different answers
for this error, answers I don't even understand.
Anyway if you could help I would be really grateful. Thanks!

The obvious answer is that you've stuffed up your kernel-config file.
Why don't you start with a copy of the GENERIC file and *gradually*
trim your file until you get a working version that satisfies your
needs?

Alternatively you can post your config-file here and hope that we can
spot the error.

You are not trying to add anything from a newer release to your older
4.3 kernel conf file are you? Like pf or something?
