Good Day,
I tried my first kernel compile today. Guided by Michael A Peters
http://216.22.163.20/Linux_Pages/kernel_build.shtml
The kernel won't start building. Foregoing building commands did not
produce alarming comments on the console. However, gcc stops at 'make
vmlinux'.
I used /usr/src/kernel-source-2.2.19 put there by Potato. The kernel
started doing weird after a few days of service: Tux was partly covered
by bush-like stuff, feet grayed out (not orange) and the screen was
shifted to the left.
I saved the errors. Honestly, this is the first time in my life and I
don't know what to make of the output. I kept some notes during the
whole exercise. To an experienced compiler the info below may be
revealing. I pointed back to the lines in question with <----xx.
Thanks for your reply.
