Compiling Linux Kernel

2010-12-18T23:01:00.004+05:30

My little knowledge in Linux Kernel started to fade as I have not been in touch for sometime now. So decided to compile the kernel to refresh my memory. I did it in Ubuntu 10.04 LTS(Lucid Lynx) with 2.6.36.1 downloaded from www.kernel.org.
This is a new installation of Ubuntu, so the development tools were not installed, installed build-essentials using apt-get, started off with menu-config which ended up in an obvious error due to ncurses library missing, installed the library and did the kernel configuration. Infact I did not change anything in the menuconfig and proceeded with compilation.
Everything went smoothly until the creation of an initrd image. To my surprise I got a “Command not found” error for ‘mkinitrd’. After some search in google, learned that Ubuntu now uses ‘mkinitramfs’. So I created the RAM disk using ‘mkinitramfs’ command. Not sure why ‘mkinitrd’ doesn’t work anymore in Ubuntu.
After an ‘update-grub’ to update grub with the new kernel and restarting, the system booted to the new kernel I compiled. Boot menu was not shown during startup, had to fix it by commenting GRUB_HIDDEN_TIMEOUT=0 in /etc/default/grub and then running an update-grub to reflect the changes.
Now I get the menu to choose which kernel to boot :-)

"More C++ Idioms"

I came across this book More C++ Idioms in Wikibooks. This is a very useful book for C++ programmers.

Ubuntu 10.04 in the horizon!

Welcome to my weblog, thanks for visiting.

The main reason I’m starting to write a weblog is to catalog my experiments and thoughts on programming, journal them so that I can refer them later. Another reason is to improve my writing skills

Besides hacking I’ll probably write about books I read and photography.
