build a kernel

[philo_neo71]

Hi,
i've read many website about compile a kernel, this is that i anderstand.

# fetch source:
cd /usr; cvs -z3 -d anoncvs@anoncvs.se.netbsd.org:/cvsroot co -P src
# everything goes into this directory
mkdir /usr/obj
# build tools (to build everything else), custom kernel, binary sets
cd /usr/src; ./build.sh -O /usr/obj -U -j 8 tools kernel=H4KK1T modules distribution sets
# install kernel:
cd /usr/obj/sys/compile/arch/*/compile/H4KK1T; su root -c 'make install'
# test kernel:
su root -c 'shutdown -r now'
# update userland:
cd /usr/src; ./build.sh -O /usr/obj install=/
# follow printed instructions about "postinstall"

# build CD image (omit "tools" if built already):
cd /usr/src; ./build.sh -O /usr/obj -U -j 8 tools release iso-image

When i hit this step >> cd /usr/src; ./build.sh -O /usr/obj -U -j 8 tools kernel=H4KK1T modules distribution sets <<
have got issues :
