Get the lkcdutils-xxx.src.rpm and install it
using rpm -i kcdutils-xxx.src.rpm .
This will place a file called lkcdutils-xxx.tar.gz
in the /usr/src/redhat/SOURCES directory. This
file is a compressed tar image of the lkcd source tree.
Unwind the source in a directory of your choice like
"/usr/src" with
tar -zxvf kcdutils-xxx.src.rpm .
This will create a directory called
"kcdutils-xxx" which will contain
the LKCD utilities source.
LKCD used the standard GCC compiler and make files. To build
the suite, cd to the LKCD src directory and
run ./configure to build configuration files.
The next step is to run make to build
the utilities, and finally run make install
to install the utilities and man pages.
/etc/sysconfig/dump # Configuration file for dump
/sbin/lcrash # The crash utility
/sbin/lkcd # Script to configure and save a crash
/sbin/lkcd_config # Configuration utility for dump
/sbin/lkcd_ksyms # Utility for reconstructing kernel symbols
/usr/include/sial_api.h # Header file for the SIAL API
/usr/lib/libsial.a # Simple Image Access Language library
/usr/man/man1/lcrash.1 # man page for lcrash
/usr/man/man1/lkcd_config.1 # man page for lkcd_config
/usr/man/man1/lkcd_ksyms.1 # man page for lkcd_ksyms
/usr/share/sial/lcrash/ps.sial # ps command implementation of SIAL

You can install the pre-built utilities from rpm by running
rpm -i kcdutils-xxx.rpm . You will still need to
patch the kernel and install the startup script patches. However you
can bypass building the utilities step.
The next step is patching and rebuilding the kernel. You will
need to patch the kernel source with the
lkcd-xxx.diff file you downloaded from
http://lkcd.sourceforge.net/.
Copy the patch into the same directory as your kernel and run
patch -p0 < lkcd-kernelxxx.diff . Make sure
the patch you use is the same version as the kernel you
are patching. Next you will need to configure the kernel to enable
crash dump support. By default crash support is turned off after
applying the patch. If you use make menuconfig
or make xconfig, the "LKCD support"
option is under kernel hacking. You will also need
to enable other kernel features you might need. See the
The Linux
Kernel HOWTO for further details.
The next is building and installing the crash enabled kernel. In the
kernel source directory run the following commands in order.
make depend
make install
make modules
make modules_install

This will build and installing the new kernel, you will also need to
copy the Kerntypes file from the kernel source to
the /boot directory. You may also need to edit the
lilo.conf file to point to you new kernel. See
http://www.icewalkers.com/Linux/Howto/Kernel-HOWTO.html
for more information on building and installing a kernel.
