Building the Kernel - Quick Question

When building the kernel26 package, does it use the flags specified in makepkg.conf?

No. The kernel uses a set of optimisations known to work for the kernel on the specified architecture. It is not recommended to change these, but i believe they are in the Makefile in the top directory of the kernel-tree.
If you want to change the flags the kernel is compiled with, you can check out zen-sources. It includes a patch so you can change the flags for the compiler and linker in the make <X>config stage

[solved] building the kernel headers for custom kernels

well, ive been building several different kernels for my laptop, so that i can test stuff. but ive got a problem with the kernel headers.
ive mirrored the arch kernel's PKGBUILD and modified some naming to get a custom kernel. but when i try to build a custmo module, it complains the headers are broken. (example, vbox_build_module).
im pasting the pkgbuild here for future reference...if someone sees something thats plain wrong, please say so.
thanks

for anything that might be missing. The error message when compiling would give you more of a clue. Off-hand, you may need to add 'generated', as I recall I needed that when the kernel moved to 2.6.33.
Problem with vbox_build_module after Kernel update.
Would you care to elaborate for us less versed in "Linux Geek" skills?

Heading to the stores - quick questions

Due to some issues discussed here and some help I received I decided to run out to shop for a few accessories so...
1. Is there wireless earplugs that are good?
<<<<<<Warning possible stupid questions>>>>
2. Can I get a card that will allow me to use internet without having to be near wireless wifi (my home or hotspots)kind of like the sprint aircard I use for my laptop?
3. Can I upgrade the battery?
4. I need a dock/charger/player. Clock radio,boombox,types, so are the brands "I..." ("Ihome", "IP23", "Ih27", etc??) Apple Brands - or are they knock offs?
5. And what about Logitech, Altec, JBL, and Bose. I know they are not Apple Brands but there are for sale in the "store" here on this website. So how can I be sure to get a good one that is better made for Itouch and not have the problems I have been having? (see my other posts)
Thank you to all of you for your help!

1. You can buy bluetooth headphones but they need a little adapter that plugs in the bottom of your iPod.
2. No sry. but you could create an network on your laptop to share the connection.
3. I believe you can send it back to apple for replacement for a fee.
4. Are you talking about headphones? Most brands are pretty good. Try them out and see if you can actually hear the difference. Also encoding your music at a higher bitrate or lossless will also aid better sound.

Recompiling the Kernel

Hey guys, I have been playing around with compiling my own kernel on Arch. I have mainly been the method outlined on the Arch Wiki about customising the Kernel26 package, from ABS and using PKGBUILD. I can successfully get kernels to compile and use them problem free.
However, I'm new to this and doing it just as a learning experience and for fun. My question is, when I come to configuring the new kernel, say by using "menuconfig" or "gconfig" for example, if I were to just leave it how it is and not change any of the selections... Would this just effectively give me the standard Arch kernel when compiled?
Being new to this kernel building business I would be grateful if someone could point me toward tips on how to optimise my kernel... What I should looking for etc. Is there a way to set the settings to optimal for your system?
Thanks in advance

If you have a kernel that's working fine, boot it and try grabbing its configuration from /proc/config.gz . The kernel in question has to have had a particular option enabled for this file to exist, but they often do (especially stock kernels).
You'll want to ungzip that and copy it to the Linux source directory (as .config) to use it.
As a side note, it's usually not worth building your own custom kernel unless you have special patches to apply, or intend to minimalize the entire configuration (and resulting modules). The performance difference is often minor.
Since you say you're just doing it for fun, well, enjoy. You will probably at least learn the names and corresponding kernel modules of all the hardware in your system if you go down the minimal route

Simple kernel compilation question

Hi,
I'm just trying to get my head around compiling my own 2.6.25.4 kernel.. I'm following the Kernel Compilation from Source guide in the wiki (using pacman/makepkg) tutorial. One thing which is confusing me is after I configure the kernel using make menuconfig and save it, when I build the kernel I still see modules I disabled streaming past. I just would like to clarify how to read the compile output so I have a clue of what is going on... e.g all the CC/[M]/SHIPPED flags.
Also, whats the difference between setting an option as a module ([M]) or built in?

What might be happening is that some PKGBUILDs copy the provided config every time the package is built, overwriting any customizations.
You should copy the $stardir/linux-2.6.25/.config file back to $startdir/config overwriting the previous one, and regenerate the md5 sum with 'makepkg -g'.
A kernel module is loaded dynamically, with modprobe or insmod. A built-in module is part of the kernel blob, so its loaded the moment the kernel is loaded.

10.7 (Build 11A511) kernel panic whilst in Safari, dragging upward the divider whilst showing all bookmarks

For reference only
An extremely rare example of a panic in Build 11A511 of 10.7.
The panic occurred whilst using Safari 5.1 (7534.48.3) but I can't say whether the bug is in Safari. Maybe an issue with third party software or hardware.

AFAIR it was after I dragged, maybe as I released the mouse, that the panic occurred.
I do not seek help with this, but if I draw a conclusion I'll post again.

[SOLVED]How to patch the kernel? And other questions

Like the same user who started this thread I'm suffering from hibernation resuming troubles using kernel 2.6.38. In that thread was posted a soluttion that involves patching the kernel.
The patch to apply is this:
http://git.kernel.org/?p=linux/kernel/g … e3e9fc8684
Waiting for the bug to be corrected and a new version supplied is not an option, because this laptop is my main computer and I heavly rely on hibernation.
Here's my trouble now. I don't know if it is possible to patch without recompiling the whole kernel, or it has to be compiled with that patch applied. I have seen the archlinux's wiki guide about compiling the kernel, but found nothing about applying patches (maybe I didn't searched with enought depth).
In case there is needed a full compilation, should I use the vanilla kernel, the Arch Linux one or any of the AUR ones (I said AUR because they're the first that came to my mind)? Should i expect a performance gain with this (apart from fixing the hibernation bug)?
Maybe i'm just doing a bunch of dumb questions, and the only thing I need is to search deeply on the wiki. In that case, please tell me. If not, I rather get some answers around kernel patching and / or compiling questions.
Edit: In addittion, it is possible that all this questions are just newbie ones, I don't know, but as I am willing to learn from this I will appreciate any info or documentation about it.
Thank you.

From the source tree (/usr/src/linux-whatever) execute
patch -p1 < /path/to/fix.patch
then recompile kernel from the source tree.
Basically that consists of executing the following commands from the source tree:
make menuconfig
make
make modules_install
cp -v System.map /boot/System.map-CUSTOM
cp -v arch/x86/boot/bzImage /boot/vmlinuz-CUSTOM
mkinitcpio -k 2.6.38-CUSTOM -g /boot/kernel-CUSTOM.img
and you need to add menu entry in /boot/grub/menu.lst
-k 2.6.38-CUSTOM should corespond to /lib/modules/2.6.38-CUSTOM (replace 2.6.38-CUSTOM with the name of your module directory, name depends on the kernel version and suffix that you gave in menuconfig). Regarding kernel configuration in menuconfig - I can't help you, you could use arch stock kernel config (zcat /proc/config.gz > /usr/src/linux-whatever/.config)
I do these kind of things this way - maybe someone else have a more elegant solution.

[SOLVED] How to add modules to build with the kernel?

Hello i´m trying to learn how to build my own custom kernel and doing it the arch way https://wiki.archlinux.org/index.php/Ke … raditional. But unfortunately dm-crypt was not included in the kernel so it all failed.
svart_alg% sudo mkinitcpio -k 3.15.6 -c /etc/mkinitcpio.conf -g /boot/initramfs-test.img

I have never don any of this before and have no idea of how to add a missing module to the kernel i´m building. So i search on internet and had a very hard time finding a good guide for this but i fond one possible solution. https://www.kernel.org/doc/Documentatio … odules.txt
svart_alg% make -C /home/nigro_alko/Kernel/linux-3.15.6 M=/home/nigro_alko/Kernel/cryptsetup-1.6.5/Makefile.in

Reason enough IMO. But anyway... you refer to the Traditional build method in the wiki, but is it possible you didn't really read it? Or maybe you only skimmed it? Did you run make menuconfig? Did you try to build everything in instead of using modules? That mkinitcpio output suggests that you did.
As suggested there for first-timers, it's a good idea to start with a kernel configuration that is known to work - the Arch config is the obvious choice, but there are other sources e.g. http://kernel-seeds.org/ .

Quick Question: When to use ( ) and when to use [ ] and why the ( *)

Hi all,
A quick question that i'm sure is very simple but is slightly confusing me. I've just started trying to learn Objective-C and am a little confused by ( ) and [ ].
I get that you use the [ ] brackets when you want something specific from an object, i.e.
[ textField textColor ]
and that you use ( ) brackets for things like:
if ( x == y) {
But I get confused when I see things like:
NSLog(@"some text here");
Why does that get ( ) brackets and why is it not [ ].
Also another point of confusion, creating methods... Why are some methods done like:
- (void)awakeFromNib
And others done like (with the additional "*" added):
- (NSString *)stringvalue
As I said, I'm sure this is very simple and obvious, but it is confusing me slightly.
Thanks in advance!

Adam:
As you already know, square brackets are used to send a message to an object, so if a object like myObject implements the method -doSomething, you can call it with:
\[myObject doSomething\];
The other use square for brackets have is to index C-style arrays, such as:
aValue = anArray\[10\]; // Get the 10-element of an array
However, because C-style arrays are rarely used in Cocoa applications (use NSArray instead) you will not see this situation often.
Parenthesis in expressions are used to group and prioritize, such as:
x = 10 * (3 + 5); // x = 80
If () statements use it to delimit the test expression. Same with while (). for () uses it to enclose the limits and increment statements, etc.
The other important use of parenthesis is in calling a C function:
result = foo(3);
means that you are calling the function named foo with the argument 3, and storing the the return value in the variable 'result'. This is different from a message because a C function is not a method of an object. They exist independently of any objects. NSLog() is a function defined within Cocoa but it is not a method. So, you call it with the traditional C function call syntax. Cocoa defines other functions like NSStringFromRect(), which takes an NSRect as argument and returns a pointer to an NSString.
And that leads me to your last question. Some methods return simple types, like int, float, or void (i.e. returns no value). These methods will have prototypes like:
\- $void$returnNothing;
\- (int)returnInteger;
Other methods return pointers to types, like:
\- (int \*)returnPointerToInteger;
\- (void \*)returnPointerToAnything; // In obj-C one typically uses id instead of void*
Returning whole objects from methods has problems and it is better to just return a pointer (the address in memory) instead:
\- (NSString *)makeAString;
The method above returns a pointer to an NSString rather than the entire object.
Good luck with your learning,
Juan-Pablo

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Quick Question about Cisco 3560 and the Web Device Manager

Alright, I have a quick question that I am curious about but I haven't found any information
about it.
When I log into my Cisco 3560 using the web portal to get to the Device Manager. Below the
diagram of the switch, then under the Dashboard there is section called Switch
Health, Port Utilization.
Under the Switch Health there is Bandwidth Used, Packet Error. Those two options just sit
at zero and do not move. The Port tilization graph is also sitting at zero.
Is there a way to make them functional?

Anyone notice performance increase or decrease of their HD when using the nVidia IDE SW drivers? particularly with a 74GB Raptor? I've also heard of burner issues when installing the IDE SW but have not used my burner yet.

Quick question about kernel

I switched my old desktop to Arch 64 in anticipation for my new rig that will be ready in a few days. My question is, will the kernel recognize the processor correctly right off the bat and reconfigure itself accordingly or do I need to reinstall the whole system? It sounds silly I suppose, but I just want to be safe and be ready for any troubleshooting if it will come my way. Also, if switching from AMD -> Intel might also cause a problem (I doubt it, but mentioning anyway), lemme know if that might cause a problem too. I don't expect any of this to, but I would just like to ask so I don't my hopes up of the computer running fine on the install it has now on the get-go.

I think that depends on the kernel. A stock kernel should be set up for generic x86-64 and take a range of processors, but it is possible to only allow the features of a smaller set, like core 2 duo, or 64 bit atoms.
If you are asking, I'm assuming it's not a custom kernel and should be fine on a different cpu
Well it's configured around an ages-old AMD 64 single-core (How many ever existed?). I set up the computer... about 3-4 weeks ago by net installation. I'll just assume that it it will take a wide range and bring up the issue up again later if it happens that the kernel hates my i7.

Quick question!! Is it mandatory that I set up my DSL through the time capsule? I'd like to leave my current modem from my provider as the primary unit for networking. So in other words can I just set up the time capsule as a back-up device for now and

Quick question!! Is it mandatory that I set up my time capsule as my DSL modem? Based on the location of my iMAC right now it would be better to just leave the modem provided by my internet provider in place. I really just want to use the time capsule as a back-up storage device for now and connnect the ethernet cable from my ISP at a later date.

Generally it is easier to bridge the TC and plug it into the router.. it then lives on the network.. it is after all, a network drive.. and you can access it via your existing connection whether wireless or wired to the existing modem.
If you really want a totally stand alone setup please tell me how you are presently accessing internet on the Mac you want to backup on the TC.

Hi guys. Just a quick question. My wife has a Mac Book Pro and when she is browsing the web she can use a two fingered gesture to go back to her previous page (by swiping from right to left). Is there any way to set that up on my iPad Mini. Many thanks.

Not in the Safari browser she can't. That is not supported on the iPad. There are other mobile browsers that do have that functionality - one is iCab Mobile.

Mine was bought last year and they were not; it they don't say "rechargeable". they're not. I started to use rechargeable as soon as the original batteries died.
