HowTo: Kernel Compilation Problem

["*Uttam* *Kumawat*" <eruttamkumawat%gmail.com@localhost>]

Dear Group Members,

I am trying to compile kernel of NetBSD 4.0.
The kernel configuration file is just the copy of GENERIC conf file in
/usr/src/sys/arch/i386/conf with the name mykernel.

I tried to compile it with build.sh
Few errors that i got and solved are as follows:

$ cd /usr/src
$ ./build.sh -u kernel=MYKERNEL

cmj-cnie-netbsd1# ./build.sh kernel=mykernel
===> build.sh command: ./build.sh kernel=my
===> build.sh started: Mon Feb 23 14:03:08 IST 2009
===> NetBSD version:   4.0
===> MACHINE:          i386
===> MACHINE_ARCH:     i386
===> Build platform:   NetBSD 4.0.1 i386
===> HOST_SH:          /bin/sh
===> No nonexistent/bin/nbmake, needs building.
===> Bootstrapping nbmake
//lots of output

objdir $dest"; rm -f obj; mkdir $dest; f i ; fi;
*** Error code 1

Stop.
nbmake: stopped in /usr/src/tools

ERROR: Failed to make obj in tools
*** BUILD ABORTED ***

Fix:
------------------------
In addition to creating the src directory I run the following as root:

cmj-cnie-netbsd1# mkdir /usr/obj
cmj-cnie-netbsd1# chown uttam /usr/obj


Again:
ERROR: nbconfig failed for mykernel
*** BUILD ABORTED ***

The reason for this error was that nbconfig tool was not found in the
/usr/src/tooldir.NetBSD-4.0.1-i386/bin
So I required to build the tools using build.sh script as follows:

$ cd /usr/src
./build.sh -a i386 tools  // -a means architecture


Again when i compiled with build.sh, stuck into the following errors:

and few ouput and at the end was

Stop.
nbmake: stopped in /usr/obj/sys/arch/i386/compile/mykernel

What should I do to fix the problem??

Thanks in advance
