A compiling procedure question.

A compiling procedure question.

[Dan Murphy]

Hi again folks.
Although I have read the howto on compiling kernels, and I have done
it successfully before, I don't understand some of the science behind
some of the procedures, so here's my question.
I compiled the 2.4.5 kernel, but during make config, I got distracted,
and in the sound section I pressed n instead of y.
I didn't realize this UN till later.  Is there a way I can go back in
and do it again without blowing away my whole source tree and starting
fresh?  If not, I don't mind, but I am hoping there's an easier way.
Some of the information in the kernel howto was a bit over my head.
thanks.

Open your /usr/src/linux/.config file in your favorite text editor and 
find the line where you said 'n' rather than 'y.' Delete the entire line. 
and then do: 

make dep bzImage modules modules_install install


PS: Why are you using 2.4.5? 2.4.17 is current.

PSS; I'm not sure anyone understands everything in .config.

Shouldn't he do a "make oldconfig" first? This way he'll get prompted for
the sound support again and he can now answer the question correctly.

Hi Dan,

	There is a way to do this, although you must be careful not to alter anything else in the .config file:

1) make a backup copy of the .config file from your /usr/src/linux directory:

	cp .config ../config-backup

2) edit the file: /usr/src/linux/.config deleting the section containing the erroneously configured option.

3) do a:	'make oldconfig' - this will only prompt you for the options that you deleted in your earlier editing session

4) continue with the rest of the steps for compiling the kernel (ie make dep / make bzImage / make modules / make modules_install)

HTH,

	--terry

Just do a "make config" until you get to the prompt you missed, and answer y.
Alternatively, you can do "make menuconfig" but I've found doing that to be somewhat confusing. Hth.

Greg.  If you want to retain all answers though you need to edit .config
and do make oldconfig as it was stated.  Simply doing make config will
blow away your existing .config and prompt you for everything again.
*smile*.

Take care.

Yeah, I've thought of that after I wrote my message.

This is *NOT!!!* correct.  Yes, 'make config' will prompt you for
everything again, but your current answers are given as defaults and
hitting enter will retain them.  I've gone through 'make config' a few
times in the early days when I had to fix one answer.  It's tedious but you
can do it.  'make oldconfig' will only prompt you for new questions, and is
designed to be run on a newer release kernel than the one it was previously
run for (so you only get asked the new questions).  'make config' and 'make
menuconfig' will edit your existing setup.

AFAIK, the only commands that will blow away your .config are 'make
mrproper' and 'rm .config'.

Hi, I would use make menuconfig. That way you can change sections that you
want without having to answer every bloody question in the make config.
