Subject: [ISSUE] dkms modules fail to build on raspberry pi (missing arm64 aarch64 symlink)
Date: Thu, 06 Aug 2020 18:17:45 +0200 [thread overview]
Message-ID: <gh-mailinglist-notifications-41a7ca26-5023-4802-975b-f1789d68868e-void-packages-24106@inbox.vuxu.org> (raw)

New issue by SumGR on void-packages repository
https://github.com/void-linux/void-packages/issues/24106
Description:
I'm using the void Linux image for the raspberry pi3. I'm trying to load an external USB Wi-Fi module. The rtl8822bu-dkms fails to build because it's looking for aarch64 kernel headers.
```
xbps-install -S rtl8822bu-dkms-20200407_1
...
...
rtl8822bu-dkms-20200407_1: configuring ...
DKMS module '88x2bu-20200407' already added, skipping.
Building DKMS module '88x2bu-20200407' for kernel-4.19.127_2... FAILED!
DKMS module '88x2bu-20200407' failed to build, please check /var/lib/dkms
for errors in the log file.
```
The DKMS build logs show this:
```
cat /var/lib/dkms/88x2bu/20200407/build/make.log
DKMS make.log for 88x2bu-20200407 for kernel 5.7.13_1 (aarch64)

/bin/sh: 1: bc: not found
make ARCH=aarch64 CROSS_COMPILE= -C /lib/modules/5.7.13_1/build M=/var/lib/dkms/88x2bu/20200407/build modules
make[1]: Entering directory '/usr/src/kernel-headers-5.7.13_1'

make[1]: Leaving directory '/usr/src/kernel-headers-5.7.13_1'
make: *** [Makefile:2001: modules] Error 2
```
I tried installing the `rpi-kernel-headers` package, but it seems to place all the headers in `/usr/src/rpi-kernel-headers-4.19.127_2` under the arch of arm64 instead of aarch64
I ran the following to get the module to build:
```
cd /usr/src/rpi-kernel-headers-4.19.127_2/
ln -s arm64 aarch64
xbps-install -Sf rtl8822bu-dkms-20200407_1
```
This seems to affect other dkms modules as well. Should the rpi-kernel-headers package be patched to always have this symbolic link so dkms modules can build? or is this something that should be fixed (or is fixed) upstream in dkms?
Kernel: Linux void-live 4.19.127_2 #1 SMP PREEMPT Fri Jul 17 14:28:57 UTC 2020 aarch64 GNU/Linux
