Compiling this driver for Raspberry Pi 3 (kernel version 4.9) does not work

[null-key]

Hi! I know there is a separate issue about failing to compile this for raspberry pi, and yes, the kernel=vmlinuz-3.10-3-rpi initramfs initrd.img-3.10-3-rpi followkernel part no longer works

Maybe there is a working fork or something?

I also tried to "just do it" without meddling with /boot/config.txt part and it almost sort of worked (insmod did not produce errors) but wpa-supplicant has troubles trying to reconfigure the device when I actually try to connect to a hotspot.

Please help

I've compiled it for a Fedora with kernel 4.4.31-11 (Qubes OS) without issue. Later kernels don't work because of Qubes not having the right kernel header packages for them on Fedora. What exact issues are you seeing?

I do not know what the issue above was but I am getting the following error sudo make

I am using 4.9.35-v7+.

I think I know which mistake I made. I forgot to sudo apt-get install raspberrypi-kernel-headers Now, the first steps go through, but the last step gives

sudo modprobe -a rtl8812au
modprobe: WARNING: Module rtl8812au not found.

I am sorry to bother you all but since I am trying this now for hours it seems I found a solution: https://askubuntu.com/questions/861717/how-to-install-d-link-dwa-172-id-20013318-driver
