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".

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.

now here's the /boot/grub/menu.lst related entry (you may add the fallback one):

kernel /vmlinuz26mm root=/dev/sda5 ro vga=773
initrd /kernel26mm.img
Should be traditional way.

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.

What is the preferred way to open a new url in a new window/popup?

Hi Guys,
I have an application that requires me to show another URL (Fedex tracking number) once a button is clicked.
what is the preferred way to do it?
Should I open a new browser or a popup?
I would appreciate if you have a code example I can use.
Thanks,
Itay

hi,
For opening a URL , you could also close previous window and open a new browser.
Follow the steps :
-> make an outbound plug in your window.
-> Add URL of type string as a parameter for your outbound plug.
->Do remember to add Component Name in the Properties Tab of View ( othervs Calling Outbound plug of win from view wont b psbl).
Write the below mentioned code to call a URL in the OnAction of button :
DATA lo_zexit TYPE REF TO ig_zexit .
lo_zexit =   wd_this->get_zexit_ctr( ).
lo_zexit->fire_out_window_plg(
    url =   'http://www.google.com'                            " string
here replace ig_zexit with your ig<applicatin name>.
Other way around is using Code Wizard ( control _ F7).
Write the below code in the onaction of button :
data lo_window_manager type ref to if_wd_window_manager.
data lo_api_component type ref to if_wd_component.
data lo_window         type ref to if_wd_window.lo_api_component = wd_comp_controller->wd_get_api( ).
lo_window_manager = lo_api_component->get_window_manager( ).CALL METHOD lo_window_manager->CREATE_EXTERNAL_WINDOW
EXPORTING
    URL            = 'http://www.google.co.in/'
    MODAL          = ABAP_FALSE
    HAS_MENUBAR    = ABAP_TRUE
    IS_RESIZABLE   = ABAP_TRUE
    HAS_SCROLLBARS = ABAP_TRUE
    HAS_STATUSBAR = ABAP_TRUE
    HAS_TOOLBAR    = ABAP_TRUE
    HAS_LOCATION   = ABAP_TRUE
RECEIVING
    WINDOW         = lo_window.lo_window->open( ).
You can choose any way whichever suits your requirements.
I hope it helps.
Thanx.

Got everything into Aperture but it is a mess. Prefered way of cleanup?

I imported several iPhoto libraries as well as a heap of aperture projects into my new Aperture library that resides on a RAIDed volume. Speed is now OK on my new Mac Pro, but what is the prefered way of sorting out over 31000 pics? How do I use the available tools in Aperture to work out a hierarchy?
Got a partial screencap here for the ones that are interested:

There is an unlimited number of ways to name files. Way back when you only had control of the file name then a lot of us tried to incorporate as much information into the file name as possible. Today things are different. Thanks to Aperture you are now able to add keywords and other metadata to your files, such as artist, location and subject.
Basically you just need to name your files with a unique name, so that two files will not have the same name. A suggestion can be the date and time stamp form when the photo was taken. This information is available from the metadata stored within the file. I use the following format for my own files:
<camera model> <date> <time>
Nikon D2X YYYYMMDD HHMMSS
Nikon D2X 20060923 234478
This way none of my files will every have the same name unless they are taken within the same second, and since I do not shot action this works for me.
As suggested by others, smart albums gives sorting a new dimension. You could theoredically put all your files in one folder and then create all the smart albums you want. You can setup smart albums, so that it include filters based on any metadata stored in your files. Keywords and smart albums makes could substitute long descriptive file names.
Don't forget to use the stacking function in Aperture, which will give you a better overview of your photos if you have many shoots of the same subjects.

[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?

[solved] Preferred way to install & update Gnome extensions

Hello there,
What is the preferred way to install and update Gnome extensions?
Do you
a) install the respective extensions from the AUR
b) or do you use the https://extensions.gnome.org/local/ page for that purpose?
What are the advantages and disadvantages of both ways?
Thanks!

Because if you use the AUR, you depend on the respective maintainers to update their PKGBUILD when a newer version is out. If they don't update, you will not receive a notification that a newer version of your extension is available.
With extensions.gnome.org/local, you do not depend on anyone else. It has no harm to your system to manage extensions like this; they get installed for just your user (in $HOME/.local/share/gnome-shell/extensions).
I know which method I prefer.
Hmm true, despite the bad effects of using the AUR prefer to use it cause I don't like to add extra interfaces for every app. But I think that is just an opinion...

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.

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

just replace all the kernel26mm by kernel26mycustomkernelname. same below with the install file and of course in your kernel config.
