Hello, all
I have a strange problem in building the linux kernel from ubuntu. (I want
to replace the kernel in ubuntu to debug install failure on qemu virtual
machine)
I downloaded ubuntu source by "git clone
git://kernel.ubuntu.com/ubuntu/ubuntu-focal.git". and because I wanted to
use a specific version, I did "git checkout Ubuntu-5.4.0-42.46" (this
version is the one used in a ubuntu installation .iso.
And you can see related askubuntu question here :
https://askubuntu.com/questions/1347390/what-ubuntu-source-version-should-i-
use-to-add-some-debug-prints-for-ubuntu-bo )
After git-checkout, the `git log` shows this result :
commit 98c4545e2d65ed35c31056f72c4da20f6b5ea0d0 (HEAD, tag:
Ubuntu-5.4.0-42.46)
Author: Khalid Elmously <khalid.elmously@canonical.com>
Date: Thu Jul 9 19:50:26 2020 -0400
UBUNTU: Ubuntu-5.4.0-42.46
Signed-off-by: Khalid Elmously <khalid.elmously@canonical.com>
To build the kernel, I did `ARCH=arm64 CROSS_COMPILE=aarch64-none-elf- make
defconfig` and `ARCH=arm64 CROSS_COMPILE=aarch64-none-elf- make -j24 Image`.
But this gives me a compile error below. What can be wrong?

BTW, when I do the same with linux-5.4.21 vanila source, it compiles ok.
Can anyone give me an advice? Could this Ubuntu-5.4.0-42.46 version have a
bug and maybe I need a patch?
Thank you!

I found from https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel, the correct
method to build ubuntu is (for ARCH=arm64 case)
* LANG=C fakeroot debian/rules ARCH=arm64 clean
* # quicker build:
* LANG=C fakeroot debian/rules ARCH=arm64 binary-headers
binary-generic binary-perarch
* # if you need linux-tools or lowlatency kernel, run instead:
* LANG=C fakeroot debian/rules ARCH=arm64 binary
But when I tried it, it went far longer but eventually it failed with error.

Based on the error message above you may not have the zfs-dkms package

Hello Alexander Kapshuk,
Thanks for the reply. Following your advice, I installed `sudo apt install zfs-dkms` ( it gave me this scary-looking warning below I just installed it, because I’ll not distribute anything)
It installs sources for zfs-dkms and I understand it contains bash script to automatically compile it when the kernel changes.
I later found I had to do these commands.
export $(dpkg-architecture -aarm64); export CROSS_COMPILE=arm-linux-gnueabihf-
LANG=C fakeroot debian/rules ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- clean
LANG=C fakeroot debian/rules ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- binary-headers binary-generic binary-perarch
Before this, I had to download gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu from https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads because I saw some compiler error related to STACKPROTECTOR compile option when I used gcc tool from linaro which was based on gcc 7.5 (I remember, the new toolchain is gcc 10.2 based).
With these, I could finally compile ubuntu 20.04!

Thank you!
