freebsd 7.1, building kernel

[gahn]

Hi, all:

I am trying to build customized kernel with "device carp" and followed kernel building procedure of the handbook. unfortunately it is failed:

lab1# make buildkernel KERNCONF=lab1
ERROR: Missing kernel configuration file(s) (lab1).
*** Error code 1

Stop in /usr/src.
*** Error code 1

lrwxr-xr-x   1 root  wheel     20 Mar  9 18:08 lab1 -> /root/kernels/lab1

tried another system and i had similar problem:

lab2# make buildkernel KERNCONF=lab2
ERROR: Missing kernel configuration file(s) (lab2).
*** Error code 1

Stop in /usr/src.
*** Error code 1

bothe system has just been patched:

FreeBSD piper_2 7.1-RELEASE-p3 FreeBSD 7.1-RELEASE-p3 #1: Mon Mar  9 16:48:31 EDT 2009     admin at lab1:/usr/obj/usr/src/sys/GENERIC  amd64

but for the kernel name GENERIC, the command work fine:

drwxr-xr-x   2 root  wheel    512 Mar  9 18:10 .
drwxr-xr-x  15 root  wheel    512 Feb 20 13:04 ..

did anyone here encounter such problem?

Thanks
