Hello,

On current master, it contains:

--8<---------------cut here---------------start------------->8---
tree /gnu/store/28xapcdbk1v5zjsxpa16qvbnhr7cqcgd-rtl8812au-aircrack-ng-linux-module-5.6.4.2-5.b8167e6

            └── LICENSE

5 directories, 1 file
--8<---------------cut here---------------end--------------->8---

Needless to say, it doesn't work.

Is this caused by a too new linux-libre kernel used?  If so, it'd be
nicer to catch such problem at build time, rather than wondering why
wifi no longer works after a reconfigure :-).

Thanks,

Maxim

According to the logs, it succesfully builds `88XXau.ko', so I think
something odd is happening in the install phase:

--8<---------------cut here---------------start------------->8---
starting phase `install'
make: Entering directory '/gnu/store/c04b4kkhcqzigq11sgyyqk17bp5ra6nd-linux-libre-module-builder-5.13.19/lib/modules/build'
arch/x86/Makefile:148: CONFIG_X86_X32 enabled but no binutils support

make: Leaving directory '/gnu/store/c04b4kkhcqzigq11sgyyqk17bp5ra6nd-linux-libre-module-builder-5.13.19/lib/modules/build'

Hope that helps,

Hello,

I looked a bit at the problem, but I have no clue as to why the Linux
kernel Makefile-based module build system changed behavior, and nothing
seems to have changed on this driver's side (its Makefile has been
untouched for about a year).

Perhaps the problem is more general to our linux-module-build-system and
Linux-libre 5.14 (I have it running still on 5.13).

I opened an issue with upstream here:
https://github.com/aircrack-ng/rtl8812au/issues/893.

Thanks,

Maxim

Fixed by Tobias with commit a939011b58c65f4192a10cde9e925e85702bacf4.
Thank you!

Closing.
