bug#68059: Mismatching defconfig options

[Lars Rustand]

I'm having trouble building a custom kernel with an included
defconfig. The kernel builds correctly with the included defconfig if I
do it manually, but when I try to build it through Guix I get an error
about Mismatching configurations in .config and
arch/arm64/configs/guix_defconfig.

Since it builds correctly manually I am sure that the defconfig does in
fact work, and it does not have any mismatching configuration. So it
must be something that Guix adds/changes in the defconfig that makes it
stop working. How can I prevent Guix from modifying the defconfig that I
tell it to use?

Here is the relevant part of my package definition:

--8<---------------cut here---------------start------------->8---
(let ((linux-package
       (customize-linux
        #:name name
        #:linux linux
        #:defconfig
        "pinephone_pro_defconfig"
        #:extra-version "arm64-pinephone-pro"
        #:source (origin (method url-fetch)
                         (uri (linux-pinephone-urls version))
                         (sha256 (base32 hash)))))))
--8<---------------cut here---------------end--------------->8---

Could you post the exact error that you get?

Guix doesn't modify the defconfig you give it, it just moves it to
guix_defconfig.  However, it then tries to verify that the defconfig was
properly applied, which is completely Guix-specific and might be the
thing that doesn't work properly.

Thanks, this must be it. I guess there is an option in the config that
does not apply correctly, but since there is no verification in the
normal build process it only causes a problem in Guix. Deleting the
problematic line in the defconfig made it build correctly, so I guess
this is not a problem in Guix, but in the defconfig I was trying to use.

This issue can be closed.

You can close issues by replying to XXXX-done@debbugs.gnu.org instead of
XXXX@, as I'm doing here.
