2.6.0 kernel compile overview

2.6.0 kernel compile overview

[James Miller]

A precocious 16 year old "Linux guru" friend (I taught him the basics
about a year ago, now he knows about 3x more than I do) recently set up a
new laptop for me with Gentoo and the 2.6.x kernel.  Despite the obvious
genius displayed in this endeavor, he forgot (as adolescents are prone to
do) to implement some fairly basic features in the kernel: namely the
system speaker and wireless networking.  This leaves me the task of
getting those things operational myself, which means recompiling the
kernel.  I've not done much kernel compiling - once or twice, if memory
serves - and all documentation I have refers to 2.4.x kernels and earlier.  
I just did a quick 'net search and couldn't find anything specific on
2.6.x kernel compiling.  At the same time, I have understood from the
friend that 2.6.x kernel compiling differs somewhat.  So, can anyone
direct me to any sources on 2.6.x kernel compiling?  I have an overall
grasp of the earlier kernel compiling process, so I'm mainly interested in
how compiling the newer kernel differs.  I generated a .config file for
the current kernel using instructions provided by the friend in question,
and of course have the kernel source on the system.  So, pointers to any
overviewish documentation specific to 2.6.x kernel compiling would be
appreciated, as would general remarks on how compiling differs with the
2.6.x kernel from compiling earlier kernels.

Thanks, James

In case anyone should get any ideas about going to the "source" for the
sort of information I hope to find: I've just been to
www.kernel.org/pub/linux/kernel/v2.6 and there is, indeed, a README-2.6
file there.  If one would expect to find the sort of information I need,
one would think that, of all places, it should be here.  Unfortunately, it
is a zero byte file.  It doesn't contain any text.  All focus on
development here, it seems clear, with explication only following as an
afterthought.

PS Nothing on the system under /usr/src/linux or
/usr/src/linux/Documentation seems very relevant, either.

There isn't much of a difference actually, the only major difference (to 
us end users ;)
is that the compilation looks cleaner.
also, now there are fewer steps to follow (thank god)
1. make mrproper
2. make menuconfig
    here you can load the config file created and add the rest of the 
necessary options.
3. make
    this takes care of even generating the bzImage (hooray!)
4. make modules
5. make modules_install (which I had forgotten and asked on this list today)
so all you have to do is copy the image to your /boot, run lilo (after 
editing lilo.conf, obviously) and you are done!

I can't find the reference right now, but I think step 3 should actually be 'make install' if you want to get a compressed kernel image and System.map file moved to either / or /boot (if you have edited the Makefile to install to /boot).  If I am wrong, someone please correct me.

Sean

Here's an "overviewish" page covering the process:

Great link - thanks for providing it.  It's got just about all I need to 
proceed with this.

Re: 2.6.0 kernel compile overview

[chakkerz]

dunno if that helps, but Linux Format had an article on how to do it in 
November (the one with the baby on the cover). I'd copy the instructions out 
(ahh ... plagerism), but someone at work nicked the magazine (darn MS 
users)...

mayhaps the local library (or the linux format web page) has the article.
