I'm trying to work way beyond my knowledge or ability, so please be
gentle.

Have installed Slackware 10 with 2.4.26 and want to try building and
perhaps installing a different kernel with the eventual aim of making a
Disk-On-Chip work. My first attempt has (as expected) failed.

In the Slackware book, Chap 4, I have reached

# make mrproper

What does this actually do? I read that it brings the kernel source into
its base state, but don't know what this means.

From KDE, I've tried to find a file called mrproper, but nothing comes
up.

In the initial installation, I said 'Install All'.

Before this, I am told to go to /usr/src/linux ..... Is this correct
or should I start in /usr/src/linux-2.4.26 ?

RTFM , from linux/README:

- Make sure you have no stale .o files and dependencies lying around:

cd linux
make mrproper
---

Should be clear enough.

Because mrproper is not a file, but a target in the Makefile. In the
Makefile you will see a line starting with "mrproper:". The lines that are
following describe what the mrproper target doesn.

/usr/src/linux is a symlink (softlink) to /usr/src/linux-2.4.26, you can
verify this with "ls -l /usr/src/linux".

With kind regards,

It means that it removes any stale files left over from a previous compile
in that source tree, much like "make clean". The main difference between
"make clean" and "make mrproper" is that it ALSO wipes out your kernel
configuration, causing any previous configuration changes you've made to
disappear. Use with caution, or better yet, avoid using make mrproper
altogether. It is not necessary.

There's a nice kernel HOWTO in /usr/doc/Linux-HOWTOs called
Kernel-HOWTO,

/usr/doc/Linux-HOWTOs/Kernel-HOWTO

which I read and followed carefully, and successfully recompiled a
kernel on my desktop machine for the first time two-to-three days
ago. You might want to have a look at it.

I observed that while the older kernel on my desktop machine took
approximately forty-seven seconds to boot, the recompiled kernel takes
approximately seven seconds less.

Hmm... I find KernelAnalysis-HOWTO there but not the one you mention.
Again a search finds nothing of that name on the machine.

I am looking at the Kernel Rebuild HOWTO on

http://www.digitalhermit.com/linux/K...ild-HOWTO.html

in conjunction with the Slackware docs that I've found

Thanks.

The Slackware.com 'book' says to:

# make mrproper
# make config
# make dep
# make clean

and then compile

so I now need to understand about what exactly these commands are
blowing away.

Are log files produced by these operations? If so where?

I'm very grateful for the help.

Thanks. I feel stupid! :-)

I'm getting bogged down in so many readme type files and had missed this
one completely.

Very grateful for the pointer and will be back soon with more questions,
no doubt.

How did it fail? What error messages, etc.?

Actually, you can build the kernel sources anywhere. Building under
/usr/src/linux-version/ is fine though.

Deletes any built kernel image, any .o files, and any .config.

You won't. You need to run "make mrproper" from that directory. The command
is make, it reads the Makefile to understand what the parameter you give it
means.

/usr/src/linux is just a symlink to linux-x.y.z on a slack install, so it
doesn't matter. But yes, /usr/src/linux is the "proper" place.

Don't. We have all been there .
