Arch Linux

There seems to be RTAI support for 3.x kernels now. Any plans to update this?

I have updated the PKGBUILD:

* Added a patch that fixes gcc 4.6 errors.
* Use option=(!strip) to avoid stripping of binaries and preventing
rtai-userspace to be build correctly
* remove lib/firmware directory from the package as it conflicts with the
dedicated firmware package
* Install sources to /usr/src/linux-${pkgver} instead of /usr/src/linux.
Makes the handling of more than one kernel src directory easier.

This issue is fixed in my PKGBUILD for rtai-kernel on my google code page.

I think only the links are missing to the sources. The source files are exist. I downloaded them yesterday.

Please stay away from this package, and use my PKGBUILDs and such from my google code svn server:

svn checkout http://neo-technical.googlecode.com/svn/trunk/ neo-technical-read-only

They are in the trunk/x86/PKGBUILDS folder.

The archlinux developers decided to remove certain parts of this aur package for no reason, therefor I do not support this package anymore on this page.

I could download the sources with makepkg!
However I also get the error message of missing modules.order.

Excuse me Arch Linux people.. why the hell was my kernel config removed and patch? What the hell is your guys's problem? I am NEVER doing development for Arch Linux ever again, you can all kiss my ass. Thank you.

If anybody knows a work around for this, feel free to submit patches! I can easily be reached via email at neotheuser@ymail.com (not gmail)

Use the -f flag along with U. sudo pacman -Uf rtai-kernel etc

You have to do the same with rtai userspace as well

Just changing to
make -j$(cat /proc/cpuinfo | grep processor | wc -l) all || return 1
has been successful for makepkg.

sudo pacman -U /home/cs/abs/rtai-kernel/rtai-kernel-2.6.35.7-2-i686.pkg.tar.xz

ended with an error:
Fehler: Konnte den Vorgang (In Konflikt stehende Dateien) nicht durchführen
Error. Couldn't finish that task (conflict with existing files)

for example
rtai-kernel: /lib/firmware/3com/typhoon.bin existiert im Dateisystem
rtai-kernel: /lib/firmware/acenic/tg1.bin existiert im Dateisystem
rtai-kernel: /lib/firmware/acenic/tg2.bin existiert im Dateisystem
etc. etc.

Also if that still doesn't work, after keeping your changes, add this line right before the modules_install command

make INSTALL_MOD_PATH=$pkgdir modules || return 1

so its like this

make -j$(cat /proc/cpuinfo | grep processor | wc -l) all || return 1
make INSTALL_MOD_PATH=$pkgdir modules || return 1
make INSTALL_MOD_PATH=$pkgdir modules_install || return 1

Also I'm throwing back in 64-bit support, it works now, and yeah. It's been working for awhile now but I never got around to it.

That's very odd. Try changing:

make -j$(cat /proc/cpuinfo | grep processor | wc -l) bzImage || return 1

to

make -j$(cat /proc/cpuinfo | grep processor | wc -l) all || return 1

Extracting the tarball and runnig makepkg in the extracted directory produces this message:

Root device is (8, 5)
Setup is 12876 bytes (padded to 13312 bytes).
System is 2823 kB

make: *** [_modinst_] Fehler 1

=> ...modules.order“ not possible: file or directory not found

I have not tried building this package with yaourt and maybe thats why it is not working, I have used this very build on several PCs and it works fine, so I am not sure.

In the very end of installing I get this error message:

Kernel: arch/x86/boot/bzImage is ready (#1)
cp: Aufruf von stat für „/tmp/yaourt-tmp-cs/aur-rtai-kernel/src/linux-2.6.35.7/modules.order“ nicht möglich: Datei oder Verzeichnis nicht gefunden
make: *** [_modinst_] Fehler 1
Breche ab ...
==> ERROR: Makepkg was unable to build rtai-kernel.

Translation:
cp: call from stat for „/tmp/yaourt-tmp-cs/aur-rtai-kernel/src/linux-2.6.35.7/modules.order“ not possible: file or directory not found

The directory exists, but not the file "modules.order"

Tested, fixed, and bumped. Thanks!

I'm updating the RTAI kernel patch now from hal-linux-2.6.35.7-x86-2.7-04.patch to hal-linux-2.6.35.7-x86-2.8-00.patch. I need to test it though first. Also firmware will be removed in next pkgrel :)

Hi, you should remove the lib/firmware directory, and maybe skip their build, since it conflics with linux-firmware. See the official kernel PKGBUILD for a way to do so. thanks

oh also rtai userspace doesnt compile yet on 64 bit so im waiting for a fix from that.

because I need to re-run make oldconfig and repost a new one. also i need to test 64-bit on 2.6.35.7

Why haven't you put it in the 'arch' line?

64-bit needs a new updated kernel config file...

nickoe: It does now.

Can this be used on x86_64?

OK, rtai-userspace and emc2 packages are done and have been uploaded!
