Hi,

We modified the shutdown utility of kernel source, to display our own customized shutdown message.

 We followed the instruction given in the http://community.qnx.com/sf/wiki/do/viewPage/projects.core_os/wiki/
BuildTheOSSource

Steps followed to build,
1.	Created a staging directory for installed binaries and headers to go 
% cd /home/kernel
% mkdir stage 
2.	Configured the override makefile stub % cd /home/kernel 
% cat >qconf-override.mk 
USE_INSTALL_ROOT=1 
INSTALL_ROOT_nto=/home/kernel/stage 
^D 
3.	Set the override environment variable to point at the makefile stub 
% export QCONF_OVERRIDE=/home/kernel/qconf-override.mk 
4.	Installed all the Header Files in the local stage 
% cd /home/kernel/trunk 
% make OSLIST=nto CPULIST=x86 hinstall 
5.	Built the Neutrino OS binaries 
% cd /home/kernel/trunk 
% make OSLIST=nto CPULIST=x86 install
But the build stopped with some linker errors as mentioned below.
