Compile Kernel rc - clarifying questions

Since I never compiled a kernel myself, and managed to screw up my system with far less sensitive tasks in the past:
I want to build 2.6.32-rc6, but have no interest/time to dive into custom configuration.
Is it save to download all the files for the current kernel26 package from svn, adjust the PGKBUILD for .32 (source, kernel name), build and install with pacman?
Can I substitute the arch patch in the PGKBUILD with the upstream patch for .32 (just skimmed through, but seemed to me that the only other patch was for aufs2)?
And would all this result in a "nearly" stock arch configured 2.6.32-rc6 kernel?

That should work. You'll want to change the pkgver to 2.6.32_rc6 or something, so you might have to change some things that rely on the pkgver in the PKGBUILD.
Alternatively you can use kernel26-git from AUR. It's a bit more bleeding edge than the -rcs, but I've been running it for a while with no problems.

Preferred way to compile kernel?

After the discussion here:
http://bbs.archlinux.org/viewtopic.php?t=4057&start=30
I'm wondering which way most people use for compiling their kernel. I've used /usr/src because its simpler and makes me feel more in control. Having an Arch package for the custom kernel has no real value, according to apeiro. Plus, using /usr/src has the kernel headers in place automatically, useful for programs that need it. (This offset by the fact that the kernel package copies the necessary files into place anyway). However, using ABS has the advantage of automating a lot of the task using Arch systems, rather than, for example, a custom shell script. (I'm trying an ABS version right now, for comparison).
Both methods are described in the wiki. I'm going to be cleaning up and expanding both shortly.
I'm asking this question in order to semi-standardize the process. Some people might say that the Arch philosophy is "There is more than one way to do everything", but I believe we could also append "but there is a best way to do it and Arch suggests that way". Now I want to find out which way is best in this case.
I'd be most interested in "I use xyz method because... [valid reason]" statements, rather than just "I use xyz".
Dusty

The 'abs' way was basically my idea - or at least the first wiki entry about it, I don't know if anyone tried it that way before. I thougt it could be a nice automatism, to have a proper kernel configuration once, tweak the PGKBUILD file, and after all is set up, all I had to change was the version number of the package/kernel source or change the config, and run makepkg then. I once made it switching from kernel24 to 26, using my own config. It worked fine. So, I thought it could be helpfull writing it to the wiki.
But this idea has some disadvantages, too. F.e., if you compile a minor upgrade, you may construct a modules mess, as a lot of files are already existing. Therefore, all cases must be thoroughly considered and configurated. Kernel addicts would prefer to patch the kernel instead of fully refetch the source.
After playing around with the idea for a while, I decided the work of configurating all possible eventuallities in compiling kernels by using abs was to difficult. Using the standard procedures seemed straight and easy to me.
So I removed my 'arch way' section in the kernel compiling wiki. Nevertheless, another user started an abs kernel wiki, redevelopping and enhancing my idea.
The idea is still attractive.

Compiling kernel module

Hello. I tryed to compile kernel module
/home/das/job/C/foo.c:
#include <linux/module.h>
#include <linux/kernel.h>
int init_module(void)
printk(KERN_INFO "Hello world 1.\n");
return 0;
void cleanup_module(void)
printk(KERN_INFO "Goodbye world 1.\n");
I created /home/das/job/C/Makefile:
obj-m += foo.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
But when i tryed to compile it with command make I take the error:
make -C /lib/modules/2.6.33-ARCH/build M=/home/das/job/C modules
make: *** /lib/modules/2.6.33-ARCH/build: No such file or directory. Stop.
make: *** [all] Error 2
My question is what is wrong and how i can compile module?

Cant boot a compiled kernel

Hi,
I want to use Arch to mess with the source of linux 3.2.7. Unfortunately, I cannot even get the regular 3.2.7 kernel to boot.
I basically followed the guide at:
https://wiki.archlinux.org/index.php/Ke … raditional
I downloaded the source, did make mrproper, make menuconfig, make all and make modules_install. I copied arch/x86/bzImage to /boot as well as System.map and created a cpio ramdisk using mkinitcpio using
mkinitcpio -g /boot/initramfs-test.img -k 3.2.7-test
In the end my /boot contained:
initramfs-test.img
vmlinuz-test
System.map-test
I tried booting with Syslinux, GRUB and GRUB2 modifying the options for all of them appropriately.
For Syslinux and GRUB if use a UUID in the root field for their respective config files I get the error that the root device cannot be found during boot. If I use root=/dev/sda4 (which is my root partition, checked it using stat /dev/sda4) I successfully mount the root partition but get an error that /sbin/init does not exist. That's weird since /sbin/init is there. I believe both of these errors have something to do with ramdisk but not sure what.
With GRUB2 booting just freezes at "Loading init ramdisk".
I read a ton on these errors online and tried all kinds of stuff and could not get it to work. Any help will be greatly appreciated!
Thanks

Thanks tomk and sorry for the ambiguous post.
I actually managed to get it finally running, I basically screwed up my .config file. This was not obvious to me at all (total noob at compiling kernels). I just used my current arch config file instead of messing with menuconfig myself and it worked. I still don't know why it works, so if you could point me to a source of enlightenment I would appreciate that. Right now compilation time is atrocious even with the -j option for make.
Regarding your question, I want to screw around with the latest pax patch and add some hooks of my own to security.h which is why I need 3.2.7.
Thanks again

How to edit GRUB for boot new compile kernel?

I compile the newest Linux kernel.
I read Archlinux wiki about how to edit GRUB for boot new compile kernel,
but Archlinux wiki do not reference to it.
Who can help me, baby?

how did you build your kernel? traditional way or arch way?
if it's the arch way (TM), here's an example of a custom kernel with -mm patch.
what I have in /boot:
-rw-r--r-- 1 root root 4.3M 2008-12-23 09:52 kernel26mm-fallback.img
-rw-r--r-- 1 root root 668K 2008-12-23 09:52 kernel26mm.img

-rw-r--r-- 1 root root 1.7M 2008-12-22 18:44 vmlinuz26mm
now here's the /boot/grub/menu.lst related entry (you may add the fallback one):
# (2) Arch Linux
title kernel26mm
root (hd0,0)
kernel /vmlinuz26mm root=/dev/sda5 ro vga=773
initrd /kernel26mm.img
Should be traditional way.

[SOLVED]Compiling kernel fails with segfault

Hi guys,
I'm out of answers.
The situation :
Compiling kernel randomly stops with : "segmentation fault" and never runs through.
Reissuing make will make it continue until it will fail at some other point.
Background:
The system feels completely unstable to say the least, but nothing 100 % reproduceable ( vuze(java) crash, firefox/chromuim flash sites crash every 120 seconds, X crashes once a day , for instance when moving tvtime around, kernel oops daily, sometimes hard lockups, logs of yesterdays oops : http://pastie.org/private/imrqdzdbejdb3jxn4czuw )
But only the kernel compile is 100 % reproduceable so this must be fixed asap.
Specs:
intel e8400,nvidia gtx260, 2 G ddr2,Gigabyte EP45-UD3R, "gigs of space", off. arch kernel 2.6.33-ARCH , x86_64, "bigtime" cooling :
cpu temps 50 C° max during compiling
What configs/packages are important ? I got paranoid and ditched my old makgepkg.conf and used a newer *.pacnew file , I used to have :MAKEFLAGS="-j3" but not in this config :
http://pastie.org/private/4ryshivi2hgyqenjlkicg
local packages:
local/gcc 4.5.0-1 (base-devel)
The GNU Compiler Collection
local/gcc-libs 4.5.0-1 (base)
Runtime libraries shipped by GCC for C and C++ languages
Anything else updated daily.
The blowup:
http://pastie.org/private/hoamev0sli7zapbr0xvpbq
What I tried:
fsck -f: it fixed two inodes, but still the same behavior
badblocks -nvs : three hours of badblock testing, 0 hits
memtest : two passed runs, no errors
stress from AUR, 15 minutes :
stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 15m
stress: info: [26841] dispatching hogs: 8 cpu, 4 io, 2 vm, 0 hdd
stress: info: [26841] successful run completed in 900s
Max coretemp was 52 C° during stress.
The usual footnote statement ^_^ :
On w7 _everything_ runs stable.
And not only stable , I'm able to OC this box to 4.5 GHz and game under w7 without a prop for hours, well this is what it was build for at some point.
Conclusion:
So I'd say hardware wise this box kicks ass and now software wise my Arch kicks me in the a**.
I doubt there is a faulty hardware part, but what else could it be ?

Update:
Trying to compile another big package just to have another result, gcc itself now :
- segfault after 4 m18 s
- segfault after 5 m50 s
Update²:
I think I found a faulty BIOS setting in my non-OC profile concerning DRAM termination, which said "normal" where "auto" would be correct.
My OC-profile has this setting correct and since I run this profile in Arch only it might explain that w7 did not fail.
Still have to verify this but i makes perfect sense, only gcc seems to trigger this. Compiling gcc still running with over 10 minutes in the game now.
After hitting 4.5 GHz with OC I must have reset the non OC-profile wrong.

I've solved the issue, infact there was a problem with the patch. Now I am able to compile the kernel.
Thanks anyway!

Update modules with compiling kernel from soure issue.

Compiling kernel from abs or aur take me much time, so i decide compile kernel from source, compilation and installation successfully but make initial RAM disk doesn't update full modules (crypto,lvm...). I specified -c option to /etc/mkinitcpio.conf but the result is the sam, non-autodectec doesn't help too. When i look into /lib/modules directory, 3.6.6-1-ARCH folder contain "kernel" folder which has a lot of things (arch, crypto, net..) and i think this is my extra modules were declared in HOOK array's mkinitcpio.conf. The another one only contain net folder so i can't boot into this kernel without having loaded others.
any suggestion for this problem? tks for reply.

am sorry, i re-tried with HOOK array without autodectect and it can load modules but there are two error:
==> ERROR: module not found: `dm-crypt`
==> ERROR: modules not found: `dm-snapshot`
ok i will try to load these modules by manually.
EDIT: i tried to load dm-mod, dm-crypt, dm-snapshot but it isn't helpful. Errors still remain. any suggestion?

Cross compile kernel

I have compiled a few kernels in an environment in which it's designed to run on - but cross compiling is completely new to me. However - I will persevere because I have wanted to learn this for a while now.
The target system is an arm based board for a NAS. I am using QEMU to install and configure a Debian system but it requires a working kernel in order to boot.
I have installed the arm-elf-gcc-base package (which I assume is the toolchain - am I wrong on this?) but I don't know where to go from there.
How do I invoke this particular toolchain to compile a kernel for the target arch?
Any other pointers or 'gotchas' would be greatly appreciated.
Thank you.

Which board is it?
Even if you manage to cross compile, kernel will need some extra configuration or patching to boot in qemu.
I have Raspberry Pi and qemu needs custom kernel to boot RPi images, but it's almost useless since there is
no support for network adapter. I have never cross compiled anything for it, but you might want to read on RPi
kernel cross compilation since there is a lot of documentation and you probably need just a different toolchain.
What I'm doing is distributed cross compiling via distcc. That way most of work gets done on my laptop, but it's
still quite slow because makepkg doesn't support distcc pump for distributing pre-processing.
I'm using toolchain provided by Arch Linux ARM project because I run Arch on RPi. If you can find crosstool config for
your board, making toolchain shouldn't be too difficult. This should get you started.

A PKGBUILD that helps you compile kernel from local source tree

I don't know if someone did this beofore. Hours ago I wrote a PKGBUILD file for compiling kernel,
it is different than the one from abs. It allows you
compile a kernel from a exiting kernel source tree and leave it clean.
honor the Archway, this means you have a clean filesystem
It is acutally because I'm currently playing with The Eudyptula Challenge.
and I'm tied our compress/decompress a kernel tree all the time. If you are kernel developer, you
may also find it useful.
The PKGBUILD file worked on my machine, I will add headers and docs later.
Oh, almost forgot: here is my PKGBUILD:

Self-compiled kernel wont boot [solved]

Hey, I compiled a kernel yesterday using the PKGBUILD from http://wiki.archlinux.org/index.php/Ker … n_with_ABS
All went fine, i made a init thing with mkinitcpio -g /boot/mykernel.img -k 2.6.18.1-mykernel and it went fine, i added it to menu.lst (grub) and rebooted,
at first it says it can't parse block device name for '/dev/sda6' (wich is my root partition) then i added rootfstype=ext3/ext2 (I tried both since i know i have one of them but cfdisk shows amoeba =/ )
but i still get the error 'cannot open root device dev(0,0)' (and also 'kinit: init not found') and then a kernel panic.
This is the boot part of menu.lst for the kernel
title [Arch mykernel]
root (hd0,0)
kernel /vmlinuz-2.6.18.1-mykernel root=/dev/sda6 rootfstype=ext3 ro
initrd /mykernel.img
and this is the hook line from mkinitcpio.conf (all other lines where either comments or ="" so i decided to exclude them).
HOOKS="base udev autodetect usb ide scsi sata filesystems"
also, i have some trouble with ata2.01 "qc timeout (cmd 0xa1)" something, is there a way to save the output of a boot?
--SOLVED--
I forgot -ARCH in the mkinitcpio -k argument.

Perhaps somebody else should help you, in that case.
I answered you original post with the understanding that you had chosen to use mkinitcpio, and were therefore familiar with the way it worked. Your follow-up suggested that this might not be the case, so I clarified my original answer.
firedance wrote:I'm not sure if that's so smart tho if i load a module thats also in the kernel
Given your previous reaction, I won't comment on whether it's smart or not - I will simply say that it won't work.
firedance wrote:when i used the right parameter it started complaining about missing modules.
Which missing modules did it complain about?
As topic states this is solved, it complained about usb-storage (wich i had compiled into the kernel) It didn't complain about ext2 since i had allready been messing around with the kernel and recompiled it with ext2 as a module. It did work to just do make modules and make modules_install for the usb-storage. But then again, maybe i was very lucky and accedently made it a module on the same time as making ext2 a module
I will recompile the kernel tonight so i am sure it is with ext2 and usb-storage only as modules.

Compiling kernel archlinux [SOLVED]

Hi everybody, I have just registered on the forum and I'm a new arch user.
I have a couple of problems that I would like to discuss about:
First problem: I downloaded all the base sistem and linux headers to make a new compilation of the kernel and after having prepared my configuration file, when I hit make, I get this message:
linux-3.8.11-1-ARCH]# make -j2
scripts/kconfig/conf --silentoldconfig Kconfig
# configuration written to .config
scripts/Makefile.build:44:
/usr/src/linux-3.8.11-1-ARCH/arch/x86/syscalls/Makefile: No such file or
directory
make[1]: *** No rule to make target
`/usr/src/linux-3.8.11-1-ARCH/arch/x86/syscalls/Makefile'. Stop.
make: *** [archheaders] Error 2
make: *** Waiting for unfinished jobs....
I checked the configuration of the kernel and I tried to remove every voice which has something to do with syscalls, but I still get the mistake.
Do you have any idea of the problem?
Second problem:
My boot manager is lilo and the system unfortunaly is configure this way:
Name Flags Part Type FS Type [Label] Size (MB)
sda1 Boot Primary ext4 104858.65*
sda3 Primary ext4 39999.54*
sda5 Logical swap 1998.75*
sda6 Logical ntfs 173213.40*
Pri/Log Free Space 2.62*
sda1 is arch linux and the kernel of the other linux distro is basically copied is in /boot of the sda1 partition. <-- is this a good way of operating for booting sda3?
Third problem:
When I boot arch linux I can't see the booting process and this annoy me tremendously, I checked on the the arch wiki for changing the boot debugging optionsbut I think I misunderstood something.
Should I only add this line udev.log_priority=8 to /etc/udev/udev.conf to see the boot debugging?
Thanks guys!

For the first problem, don't do that. You should never build and install packages directly on an Arch system. Read up on makepkg and PKGBUILDs to learn how to build packages the right way now. It will make your life easier later.
https://wiki.archlinux.org/index.php/Makepkg
https://wiki.archlinux.org/index.php/Pkgbuild
You can get the PKGBUILD for the kernel here (or by using one of the PKGBUILD retriever utilities, e.g. pbget:
i686
x86_64
Aside from ensuring that the resulting file are properly managed by pacman (file tracking, dependency resolution), the PKGBUILD contains the full set of build instructions and will provide a good place to start if you want to customize them.
For the second question, having multiple kernels in the same boot partition is fine, but you need to be careful to prevent one distribution from messing around with the files of the other, e.g. when updating your boot loader. I would probably let one distro fully manage the boot directory and manually copy in kernel images from the other when I need to.
For the third question, does the following answer it? https://wiki.archlinux.org/index.php/Di … t_messages

Compile kernel 2.4 arch

Hi guys, I need to compile manually the kernel 2.4 on archlinux. I need to do that for an university course I'm following. I did that several time with version 2.6 on gentoo, but now with version 2.4 on arch I got a problem: it seems I'm missing "genksyms" (I don't know exactly what it is). Can you tell me how to find and install it? Any other suggestion to deal with the compile process of kernel 2.4?? Thanks

Are you aware that there are certain intricacies involved in building a 2.4 kernel on a system that is tuned for a 2.6 kernel?
Does the word 'toolchain' mean anything to you without having to resort to google? If not, how about 'glibc'?
I.e. do you know what you are trying to accomplish?
I believe it's better to give informations in a post instead of writing questions to someone who's looking for a solution to his problem. However, I know that there can be differences, but since I never used the kernel 2.4 I don't know about the consequences. Again, it would have been better for me to learn something from your post.
While it might not be what you were looking for, there is some very constructive material in my post. My questions - when answered - would have allowed you to put your own question in perspective.
I did not say that I wouldn't try to answer to your questions, but I just believe that yours is not the way to help an user. Asking to "google it" is not very kind to me. However I can find all the other informations I need by myself, obviously, I was just talking about the way you answered. Sorry for the OT, this OT ends here, for me.
If you refuse to do that, that's your choice. I'm trying to make you think about the ramifications of your little project.
People who say or think complicated things are easy usually don't know anything about it .
I'm not refusing to do that

Compiling kernel module on 64bit Solaris10 amd64 platform

Hi,
i m compiling my kernel module in Solaris10 booted in 64bit on amd64 platform.
i m using two extra flags: -xarch=amd64 -xmodel=kernel
But i m getting error s as follows:
ld: fatal: file -c : open failed: No sich file or directory.
ld: fatal: symbol '_fini' is multiply defined.
(file /opt/SUNWspro/prod/lib/ctri.o type=FUNC; file bcmod.o type=FUNC) ;
ld: fatal: symbol '_init' is multiply defined.
(file /opt/SUNWspro/prod/lib/ctri.o type=FUNC; file bcmod.o type=FUNC) ;
ld: fatal: file processing errors: No output written to a.out
can somebody give hint .

I think you need to take this question to an Open Solaris community forum at http://www.opensolaris.org
Your question is not about the C compiler, but about how to build the Solaris kernel.
