Ccache and kernel compilation -SOLVED
I have installed ccache and am compiling the kernel from the commandline, but can't get ccache working. Compiling takes a while, and ccache -s says there are no cached files. Read the wiki and man ccache, am a bit confused, and thought I had done what they suggested, but obviously not.
Can anyone help me set this up? Preferably I would like all compiling to be done using ccache, not just using makepkg. I think I have to softlink ccache and gcc, not sure how to do this.
Happily, my custom compiled kernel boots fine, sound is the only thing not working.

I have discovered one of the cardinal rules for using Arch...if something doesn't work, check for typos.
ccache is working now, makes kernel compiling so much easier.
I'm having a read finding out the pros/cons of using PKGBUILD for a custom kernel. Not too fussed, everything works and it boots ridiculously quickly.

Vmware-server 1.0.1 and kernel *.19 [solved]
Hi,
since I upgraded the kernel from 2.6.18 to .19 I cant get my vmware-server running. Has anybody else this problem?
I ran vmware-config.pl again but it always crashes with:

Unable to build the vmnet module.
I try to create this error in english later, but maybe u know the problem already. I found sth about a any-any-patch but I couldnt find out if this is related to arch.
Would be great if somebody could give me a hint.
Btw, Merry Christmas [/i]Merry Christmas to you too.
Yes. The problem is related to the any-any-patch.
Get the latest version of the patch and run it. That should solve the problem.
If for whatever reason it fails then, and only then, look for this file:
/lib/modules/2.6.18-ARCH/build/include/linux/version.h, and make sure it contains a line for the UTS_RELEASE, and if it does not, add at the end the following: define UTS_RELEASE "2.6.19-ARCH"
Then run the patch again.
Hope it helps.

1g lowmem?
Many machines now have exactly 1Gb ram and the standard memory split on i386 does not allow you to use more than 896Mb ram without enabling high memory for at least 4Gb. The problem is that this incurs an overhead whereas we can simply change this split with this patch to allow i386 architectures to use up to 1Gb ram without enabling highmem. This is configurable if HIGHMEM is disabled.
I also don't know if his old patches have the patch or if the current will work on the 2.4 kernel..
Just looked around and found the 2.4 are now Ick patchset and i don't see that... CK does have a server patch... If anything just get the 2.6 CK server patchset... 2.6 is stable, but how am I to say I've only used 2.6... Go with 2.6 ck server.
websites: CK patchset 2.6

i really want a huge kernel space, and i can't find the 4G kernel space vm patch for 2.4 at these links
thanks anyway -
[solved]wacom doesn't work after upgrade to xorg 1.6 and kernel 2.6.29
hello..
i have already posted about that in testing-forums, but since xorg 1.6 and kernel 2.6.29 have moved to extra, though i'd create a seperate topic about that.
after i have upgraded to xorg 1.6 and kernel 2.6.29 my wacom device (as built-in, not usb) on my thinkpad x41t stopped working.
before upgrade i have used xorg with hotplugging enabled. everything worked fine.
after wacom stopeed working i removed everything regarding input devices from xorg.conf -> no change
put an fdi-file for wacom -> no change
installed linuxwacom-dev -> no change
i don't really know, if it's a kernel or an xorg issue. loading wacom drivers manually still doesn't solve the problem. no warnings or errors about wacom in xorg-log or messages.log
how could i check, wether my system recognizes the device properly at all? it doesn't show up in lspci or in lsusb.
any help would be great.
Last edited by lynucs (2009-04-14 18:57:17)well, upgraded again to xorg-server 1.6, disabled hotplugging, installed linuxwacom-dev from aur and the wacom works as allways. (had to edit xmodmap one more time, since kbd returns other keycodes than evdev does :-| ). no matter, done is done.
but intel driver returns broken graphics if i rotate screen with xrandr.
i guess there is no way around this execpt switching to the ultra-slow legacy driver?
just for comparison - glxgears fps:
intel: ~900fps
intel-legacy: ~280fps

[SOLVED] Can't get ccache and colorgcc to work together
Hi all,
Has anyone figured out how to get ccache and colorgcc to work at the same time? I can only get one or the other, but not both.
If I put them both in the path, with colorgcc first, then "g++" invokes colorgcc, which then calls /usr/bin/g++, skipping ccache.
If I put ccache first in the path instead, then running "g++" invokes ccache, which then calls /usr/bin/g++, skipping colorgcc for some reason.
Putting colorgcc back to first in the path, then editing /etc/colorgcc/colorgccrc means I can set the compiler paths to point to ccache. However then running "g++" invokes colorgcc, which calls ccache, but then ccache seems to call colorgcc again, which calls ccache, which calls colorgcc, etc, etc.
Perhaps I'm missing something, but I can't see how you tell ccache where the compiler binaries are located, as this seems to be the problem - ccache autodetects them, and always seems to pick the ones I don't want!
Any suggestions?
Last edited by Malvineous (2011-05-03 01:29:48)Ha, ok, as usual as soon as I post in a forum I stumble across the answer. Turns out there's a CCACHE_PATH environment variable you can use to tell ccache where to look for the real compilers. It doesn't seem to work setting this to point to colorgcc, but putting only colorgcc in the path, editing /etc/colorgcc/colorgcc to point to ccache, then setting CCACHE_PATH=/usr/bin seems to do the trick...
But if there's a better way please let me know! -
Compiling and Installing Compiled Kernel
Hi everyone, today i followed the "Kernel Compilation From Source" (https://wiki.archlinux.org/index.php/Ke … rom_Source) ArchWiki to compile a kernel downloaded from kernel.org. And i use the second method to compile and install with makepkg.
When the compilation is done, it can't be installed because the name of the file.
I know i must specify a new name for the new linux image and the System.map to have two or more kernels installed. But "where" in the PKGBUILD i must change the name of the files???
I'm using the PKGBUILD from the wiki:
pkgname=kernel26-my
basekernel=2.6.32.8
pkgver=2.6.32.8
pkgrel=1
pkgdesc="The Linux Kernel and modules"
arch=('i686' 'x86_64')
license=('GPL')
url="http://www.kernel.org"
depends=('module-init-tools' 'mkinitcpio')
provides=(kernel26)
install=kernel26.install
build() {
LOCAL_VERSION="$(grep "CONFIG_LOCALVERSION=" $startdir/.config | sed 's/.*"\(.*\)"/\1/')"
cd ..
make || return 1
mkdir -p $startdir/pkg/{lib/modules,boot}
make INSTALL_MOD_PATH=$startdir/pkg modules_install || return 1
# There's no separation of firmware depending on kernel version -
# comment this line if you intend on using the built kernel exclusively,
# otherwise there'll be file conflicts with the existing kernel
rm -rf $startdir/pkg/lib/firmware
install -Dm644 "System.map" "$startdir/pkg/boot/System.map26$LOCAL_VERSION"
install -Dm644 "arch/x86/boot/bzImage" "$startdir/pkg/boot/vmlinuz26$LOCAL_VERSION"
# Change the version strings in kernel26.install
sed -i \
-e "s/KERNEL_VERSION=.*/KERNEL_VERSION=\"$basekernel\"/" \
-e "s/LOCAL_VERSION=.*/LOCAL_VERSION=\"$LOCAL_VERSION\"/" \
$startdir/kernel26.install
And also the kernel26.install
KERNEL_VERSION="2.6.32.8"
LOCAL_VERSION="-MINE"
post_install () {
echo ">>> Updating module dependencies..."
/sbin/depmod -A -v ${KERNEL_VERSION}${LOCAL_VERSION}
echo ">>> Creating initial ramdisk..."
mkinitcpio -k "${KERNEL_VERSION}${LOCAL_VERSION}" -g "/boot/kernel26${LOCAL_VERSION}.img"
post_upgrade() {
echo ">>> Updating module dependencies..."
/sbin/depmod -A -v ${KERNEL_VERSION}${LOCAL_VERSION}
echo ">>> Creating initial ramdisk..."
mkinitcpio -k "${KERNEL_VERSION}${LOCAL_VERSION}" -g "/boot/kernel26${LOCAL_VERSION}.img"
Thanks in advance.
Last edited by Hyugga (2010-11-11 02:48:14)When installing the kernel there is some problem when the "mkinitcpio" is running: sd_mod error.
I can install and boot the kernel afterwards but when i get to kdm, the keyboard and the touchpad/mouse doesn't work.
I double checked the .config file and i have enabled the keyboard and the mouse options.
What can i do?
Thanks... -

I added nosmp and the other parameters at the install/rescue cd's suggestion. I tried using the microcode package (I have a P4 HT) as suggested by someone in another thread.
I've found that the freezes will happen at the beginning of heavy CPU or disk usage (such as compilation or pacman db parsing). The hd is not the original one from this system (it was a hand-me-down), so I don't think that's the problem. The video card is different and the RAM is new. The only components that are still around are:
P4 HT processor (2.60 ghz)
Albatron PX865PE II
Enermax power supply
Any ideas? It also says "bad eip value" when the system has kernel crashes (especially on boot).

[Solved] Kernel compilation newbie questons.
Hello
That will be my first kernel compilation and i have few questions.
1.When i compile kernel from this(http://wiki.archlinux.org/index.php/Ker … sers_Guide) tortial i havo to do this:
http://wiki.archlinux.org/index.php/NVI … tom_kernel
2.When i compile modules to kernel there are diffrence when i have them as modules (lsmod)?
Thanks for anserws.
And I'm sorry for that questions.
Last edited by SpeedVin (2009-05-19 12:13:48)Hi SpeedVin,
1. you must recompile nvidia driver if you are planning to use custom kernel.
You can do this by either using ABS or with yaourt -Sb command. The link you posted to wiki says it right.
2. When compiling drivers directly into kernel, they will make size of kernel bigger, but udev will not spend so much time autoloading them. The best practise is to have all needed modules compiled in kernel and turned autoloading modules off in /etc/rc.conf. Be aware, that not all modules are loaded when lsmod - e.g. when you plug in USB disk, udev loads needed modules (usb_storage, correct coding, etc.).
And last but no least, i can't get why is wiki giving advise to compile kernel like 10 years ago. If I were you, I would NOT choose this way. It is much easier to compile kernel with ABS, or with yaourt -Sb. All you need is to edit PKGBUILD and uncomment one of these lines:
#make menuconfig # CLI menu for configuration
#make xconfig # X-based configuration
#make oldconfig # using old config from previous kernel version
I am a happy user of xconfig menu (you need Qt3 package to use xconfig).
Configure your kernel as you need, save config file and exit configuration, compilation goes on and after 30-50min you have your kernel ready to install.
If you want a save option you can also edit and uncomment # pkgname=kernel26-custom to have your kernel alongside with -ARCH stock kernel. Note, that you must also edit nvidia's PKGBUILD if you want to use it this way.
I think this way will save you lot of time and the result is better, but it's up to you of course. -
Add patch to kernel so solve Touchpad bug
Hi!
The Touchpad for some ASUS models was not being recognized. A patch has been released here:
https://bugzilla.redhat.com/show_bug.cgi?id=1110011
I would like to know if this patch will be applied to Arch Linux kernel or I should start a bug ticket. As of linux 3.16.3-1 the patch doesn't seem to be implemented.
PS: If I wanted to implement the patch what would be the easiest way? I'm guessing I should get the kernel source, apply the patch and compile, but I don't know how could I install it afterwards in Arch Linux so I can easily uninstall it without harm if it doesn't work.
Regards!jasonwryan wrote:
Read the Kernel compilation page on the wiki (using the ABS method).
You can install your patched kernel alongside the vanilla Arch one and choose which you would like to boot from. Simple.
Hi, thank you for your answer, I tried that and got a patched kernel running which almost solves the problem. Should I open a bug issue about this or will it eventually be implemented? I think it already is in Fedora, for example. -

I think the new xorg-server is the problem as it isn't supported by this nvidia driver yet.
You could try to install the nouveau driver until nvidia comes with a new version of the 173 branch that supports xorg-server 1.10, see: https://wiki.archlinux.org/index.php/Nouveau for information. As lower-grade options, you might also consider xf86-video-nv and xf86-video-vesa.
Should i uninstall nvidia driver, then install it?
I think thats the easy way yes, else you have to blacklist the nvidia kernel module.. check the wiki link of nouveau for details. -
OK - I've spent all afternoon searching and reading and, either I'm stupid, or the answer isn't obviously out there.
Since I reckon it's probably the former - try and speak slowly for me
I want to use my desktop primarily as an audio workstation - by which I mean I want to run things like ardour and do audio recording/editing etc.
I've got most of the tweaks to my system done - but I'm really not sure what, if any, changes I need to make to my kernel. I'm currentlyu running the stock kernel and things generally seem fine - but I'm not sure if I could improve things.
The linux-musicians website suggests the following changes to the kernel config:
CONFIG_HZ_1000=y
CONFIG_HZ=1000
CONFIG_PREEMPT_RT=y
CONFIG_PREEMPT=y
Is this still necessary with recent kernels?
Any advice/suggestions welcome.CONFIG_PREEMPT_RT is for the real-time kernel only. If you're doing serious DAW stuff, then you'd probably want (note, not NEED I think) that. Unfortunately, the kernel I use to get rt (kernel26-ice) has just upped to 2.6.30 yesterday and as a result the rt-patch doesn't work, till they come out with a 2.6.30 one.
Best to wait for the proper rt-kernel patch to come out, then use the kernel26-ice PKGBUILD to compile it with the above options. I have the kernel compiled here from a month back, but not sure if there's anyway to send it to you. -

Do i need to update other .sar files from sapnet ?
Did somebody have the same error ?
Thanks in advance .
Best Regards.We had this same issue today and folks that are not familiar with sapcpe can really be at a loss on this error, so I'm updating some of these older threads for clarification.
When sapcpe is active, you actually have two copies of the SAP kernel on your Unix file system:
/sapmnt/SID/exe - Which is probably where you update your kernel (this version was at 201)
(aka: /usr/sap/SID/SYS/exe/run)
/usr/sap/SID/DVEBMGS##/exe - A location many don't know about (this version was at 133)
Typically, sapcpe keeps these two locations identical and there are no mismatch errors but if anything happens to your configuration, the next time you update your kernel in /sapmnt/SID/exe, the replication does not occur and the mismatch happens as seen in (dev_disp or dev_disp.new):
***LOG Q00=> DpSapEnvInit, DPStart (18 22336) [dpxxdisp.c 1283]
DwSLCheckVersion: shared library version mismatch:
shared lib "dw_xml.sl" version 133 <-> kernel version 201
shared lib "dw_xtc.sl" version 133 <-> kernel version 201
shared lib "dw_stl.sl" version 133 <-> kernel version 201
shared lib "dw_gui.sl" version 133 <-> kernel version 201
shared lib "dw_mdm.sl" version 133 <-> kernel version 201
This is made even more confusing because if you do an "ldd /sapmnt/SID/exe/disp+work" the results will tell you that it's reading those files from where you just patched your kernel. That ldd is incorrect, however. If the two copies of the kernel are not in sync, some files will indeed be loaded from /usr/sap/SID/DVEBMGS##/exe which will not match the other files that are loading from /sapmnt/SID/exe and you'll have the mismatch error.
Short Term: You can delete the contents in /usr/sap/SID/DVEBMGS##/exe and then everything is loaded from /sapmnt/SID/exe.
Long Term: Correct the configuration of sapcpe so that it keeps everything in sync and you don't have dualing kernels. (See note 1104735) -
[OCaml, lablgtk2, lablrsvg] My program doesn't compile (solved)
Hi,
I wrote few months ago (I used Ubuntu at that time, I just have installed ArchLinux one week ago) a little OCaml program which makes use of the lablgtk2 and lablrsvg libraries (OCaml bindings to gtk2 and rsvg).
I installed ocaml and lablgtk2 (which normally contains lablrsvg, librsvg being flagged as a dependency), but when I try to compile, I get an error :
$ ocamlc -w ys -I +lablgtk2 lablgtk.cma gtkInit.cmo lablrsvg.cma unix.cma entrelacs.cmo io.cmo entrelacs_IHM.ml -o Entrelacs
File "entrelacs_IHM.ml", line 1, characters 0-1:
Error: The file /usr/lib/ocaml/lablgtk2/lablrsvg.cma is not a bytecode object file
make: *** [Entrelacs] Erreur 2
The others files entrelacs.cmo and io.cmo doesn't need lablgtk2 (nor lablrsvg), and they compiled fine.
In /usr/lib/ocaml/lablgtk2/, the file lablrsvg.cma exists, and `file' tells me that this is an "Objective caml library file (.cma) (Version 007)"
The same program compiled fine when I used Ubuntu.
What's wrong?
Thank you
(solved after the update of lablgtk2 today)

Another argument for the command line is that it's simple. There are 16 distinct dialogues involved in adding a new jar to a library in jBuilder... There may well be less than 16 characters in the equivalent edition to the equivalent build command line. That's an extreme case, I admit, but it goes to disprove the notion that IDE's are simpler for noobs.
Also, it's easier to get help on command line usage... because it's all text based you can just copy & paste the problematic command and it's output, and the eggspurts (tm) can do likewise with a response... and there are limited number of command lines out there... and *nix, windows, and mac cover maybe 99.5% of java users... and the eggspurts are likely to know all three (colectively if not as individuals) fairly well, because they deal with them all day every day.
My belief is that noob's are better off at the command line until such time as they need (not just want to play with) a visual debugger... at which time its time to download netbeans and eclipse, and see which one suits you better... if you have money to splurge I'd also evaluate intelliJ... But avoid jBuilder, 2008 is total carp! The FREE eclipse is (IMHO) "nicer to use", and it has a LOT less bugs.

How to determine the kernel compilation time stamp ?
Hi, all
sorry of this is a miss post.
I'm trying to find out the date (time stamp) using the
"uname -a" command , but I'm not sure this is the correct way , because the
the output of the command returns the kernel release date and I'm not sure this is the
correct time
Any suggestions ?
VictorI'm referring to the date the kernel was actually compiled .
My question was if the output of the command "uname -a" contains the kernel compilation date, because
the "man uname" and "info uname" says that the output contains kernel release info.
Or is there another way of determining the actual date(time) when the kernel was compiled. -
Issue after kernel compilation
I've compiled my own kernel based on the arch linux default kernel its configuration file. I simply executed make clean && make dep && make modules && make bzImage && make modules_install. Afther the depmod I've built a ramdisk with mkinitcpio.Unfortunately I'm not able to boot into my new self-compiled kernel. Here you can see my /boot/grub/menu.lst:
# (0) Arch Linux Self-compiled kernel
title Linux 2.6.30.5 [/boot/vmlinuz-2.6.30.5]
root (hd0,0)
kernel /vmlinuz-2.6.30.5 root=/dev/sda3 ro
initrd /kerneltest.img
# (0) Arch Linux
title Arch Linux [/boot/vmlinuz26]
root (hd0,0)
kernel /vmlinuz26 root=/dev/sda3 ro
initrd /kernel26.img
While booting into the new kernel the next error message about the root device shows up. I've noticed I'm able to boot the default arch kernel that's using the same root device (=/dev/sda3) on this desktop.
Waiting 10 seconds for device /dev/sda3
Root device /dev/sda3 doesnt exist, attempting to create it
Error: Failed to parse block device ids for /dev/sda3
Error: Unable to detect or create root devide /dev/sda3
If you would like to see my partitions:
/dev/sda1 /boot ext2 defaults 0 1
/dev/sda2 swap swap defaults 0 0
/dev/sda3 / ext4 defaults 0 1
/dev/sda4 /home ext4 defaults 0 1
Who can help me with this issue? Thanks.
Last edited by Nando (2009-09-05 15:40:04)I've compiled a new kernel but the same issue remains. I executed some important changes in my kernel config: CONFIG_SCSI=y, CONFIG_ATA=y, CONFIG_EXT4_FS=y (instead of being modular as in the default arch linux kernel). I also inserted the "aufs" lines, but they were gone in my .config file after the kernel compilation.(I think it was after make dep)
A "diff" of both .config reveals that aufs is almost the only difference. (I've already mentioned the stuff that used to be modular and is now built-in.)
