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)

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!
