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@xxxxxxxxxxxxx> Date: Thu Jul 9 19:50:26 2020 -0400 UBUNTU: Ubuntu-5.4.0-42.46 Signed-off-by: Khalid Elmously <khalid.elmously@xxxxxxxxxxxxx> 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! Chan Kim |
