Another kernel recompile question

mikieboy · 09-01-2006, 04:39 PM

I want to recompile my existing kernel to make a few minor changes but using the rest of the configuration as it is without having to go through every compile option. So after doing;

cp /boot/config-kernel_version .config

do I run make menuconfig or make oldconfig ?

This should answer your question.

Use make menuconfig then second option from bottom once it loads is Load configuration from file type in /boot/config-2.?.??-??? replacing the question marks with the actual numbers of the file then go through and change the configuration as you want when you exit it will ask you if you want to save new configuration say yes.

Thanks guys.

Since my original post I have read that /boot/config-kernel_version should be copied as .config to my quote: "kernel source directory".

Is this /usr/src or /usr/src/linux?

Yup, however, the /linux is a symlink so you will want to double check and make sure you've got it pointing to the correct source directory.

My /usr/src/ dir looks like

Code:

$ ls -lh
total 40M
lrwxrwxrwx  1 root src    39 2006-08-31 10:23 linux -> /usr/src/linux-headers-2.6.16-2-686-smp
drwxr-xr-x 17 root root 4.0K 2006-08-31 09:28 linux-headers-2.6.16-2
drwxr-xr-x  5 root root 4.0K 2006-08-31 09:28 linux-headers-2.6.16-2-686-smp
drwxr-xr-x 21 root root 4.0K 2006-08-30 18:03 linux-source-2.6.16
-rw-r--r--  1 root root  40M 2006-08-18 14:59 linux-source-2.6.16.tar.bz2

Well /usr/src/linux is a symbolic link you create to where you have your real kernel sources but that would be essentially correct except nothing would go into the /usr/src/linux but the actual source tree your better off just loading the file into menuconfig make the changes then save.

Code:

ls -l /usr/src/linux
lrwxrwxrwx 1 root src 21 2006-08-27 23:09 /usr/src/linux -> /usr/src/linux-2.6.17

Thanks again for all your replies. I reckon I now have a better understanding of what to do.
