Avoid checking config sha256sum while building kernel

Hi
I try to build my own kernel, that would work with Anbox.
I use Arch Build System.
I modified config file and included

CONFIG_ASHMEM=y
CONFIG_ANDROID=y
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_BINDERFS=y
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder"
CONFIG_SW_SYNC=y
CONFIG_UHID=m

options.
However, when I run makepkg -s, it fails when checking config sha256sum.
And says at least one file isn't correct.
How to avoid checking config file sha256sum, to build anyway?

Cheers

Re: Avoid checking config sha256sum while building kernel

https://wiki.archlinux.org/title/Makepk … _checksums or make the corresponding sha256sum entry in the pkgbuild read 'SKIP' https://wiki.archlinux.org/title/PKGBUILD#Integrity

FWIW if you want to test a ready made kernel, the linux-zen package includes these flags.

FWIW if you want to test a ready made kernel, the linux-zen package includes these flags.

That changed with 5.18 Anbox#Using_Linux-Zen / https://bugs.archlinux.org/task/75017 the kernel developers preferred memfd to ashmem.

Thank you, that fixed this problem.
However, now it says:

GnuPG#Searching_and_receiving_keys

The kernel build will drop the CONFIG_ASHMEM=y option as it is no longer supported in 5.18+ as I linked above.  You would need to revert the removal of ashmem from the kernel or use DKMS modules as also mentioned in the link.

So I'm trying in vain?
I wanted to build this kernel to have Anbox with 5.18.
But it is not possible anymore, right?

Have you tried Anbox#Installing_anbox-modules-dkms?

Re: Avoid checking config sha256sum while building kernel

Yes.
But it also works up to 5.15.
However, I installed Linux-LTS + Anbox DKMS modules.
And now I enjoy Anbox!
