    Compiling a Kernel on a PPC Machine
    Contributed by fkoclas on Friday, November 09 @ 06:10:54 GMT

    Linux
    I never ran into much trouble when compiling a Linux Kernel on my PC (using make menuconfig, make install, make modules, make modules_install etc etc), but every time I try to compile a kernel (2.4.x) on a PPC machine (I tried on those three : PowerMac 7300, G3/266, and G4 Cube 450), it just won't work!

    The kernel configuration using menuconfig works fine and everything but when I try to compile it, it just ends up saying that there is no rule to "make". Is it possible to compile a kernel on a ppc machine or am I missing something here?

    DanielS: You'll probably want benh's kernel tree, apt-cache search benh.

    Yes, it is possible to compile a kernel on PPC machine.

    Yes, you are missing something 🙂

    I recommend the following:

    - Get on the debian-ppc mailing list

    - Get the Debian source for 2.4.10

    - Get and apply the PPC patch

    - Get and apply the XFS patch while we're patching 😉

    Now try your normal kernel building techniques. I hope on Debian you are building kernels with make-kpkg, this is a big grief relief.

    The advice above is very good. Also remember than on PowerPC based systems you don't need to make a compressed boot image, so typing "make vmlinux" instead of "make zImage" is usually called for. That is, assuming that you have the correct source code.

    Unfortunately, Linus' kernel often doesn't have the latest PowerPC changes incorporated into it. With time everything gets in and the kernel will be compilable with the source from kernel.org, but this doesn't happen very quickly.

    So, it pays to get the source from the PowerPC kernel developers themselves. If you're using a newer PowerMac (e.g. the iBook2) then right now this is a must. Fortunately, it's quite easy to obtain.

    If you have rsync installed, then you can obtain the latest versions of the benh development version of the kernel source by running the following command:


    rsync -arvz --delete rsync.penguinppc.org::linux-2.4-benh [directory]

    where [directory] is the name of the directory you would like the source to be downloaded into. (See the the rsync man page for more info.)

    If you'd prefer to download Debian packages of the kernel source, they're seperated out into a base kernel source package and then an additional patch package. For example, I see right now that there are "kernel-source-2.4.13" and "kernel-patch-benh" packages -- these might be a good place to start. Unfortunately I can't say more about them since I've never used them.

    Good luck. 🙂

    Let me save you some hours of frustration...

    Get the latest kernels using rsync. I suggest the benh tree...

    type in this command to get the latest kernels:

    rsync -avz --delete source.mvista.com::linux-2.4-benh

    This will download the source into the destination_path directory. Note that these kernels are specifically tuned by clued people so that they compile nicely on PPC (PowerMacs).

    I'm running on 2.4.14 right now on my ibook2 G3 500.

    Hope this helps

    Thank you all, it finally compiled =) Whew 1 hour and a half to compile it on a 7300/200 (604e 200mhz with 160mb ram) 😉

    But now there is a weird problem.. it does not work well with the ADB keyboard everytime i press a key it enters something else for example a=a s=nothing d=1 f=2 g=4 h=3 j=l k=' l=k etc...

    How could this be fixed?? I've never seen a problem like this before

    Hmmmm it also does it when I go back to kernel 2.2.19... 🙁 any ideas??? I did not have the time to install telnetd or sshd yet, so i cannot use it remotely =(

    It won't even let me use keyboard properly in single user mode.

    This looks normal though:

    ADB Keyboard at 2, handlers set to 3

    Detected ADB keyboard, type ISO, swapping keys

    input1: ADB HID on ID 2:2.05

    adb: finished probe task...

    You need to reconfigure your console. dpkg-reconfigure console-data

    They changed the handling of scancodes (or something like that) recently. So just ssh into the box and change it.
