Hello, I am trying to install the driver for my AWUS1900 (RTL8814U) for my raspberry pi 3 but i get an error when trying to build it with the kernel. I tried a diferent kernel but it still won't work.

Here is the driver I want to install. https://github.com/aircrack-ng/rtl8812au/tree/v4.3.21

Here is the error i get when i try to install it.

root@kali:~/rtl8812au# make RTL8814=1
make ARCH=armv7l CROSS_COMPILE= -C /lib/modules/4.9.41-Re4son-v7+/build M=/root/rtl8812au modules
make[1]: Entering directory '/usr/src/linux-headers-4.9.41-Re4son-v7+'

make[1]: *** No rule to make target 'arch/armv7l/Makefile'. Stop.

Makefile:1732: recipe for target 'modules' failed
make: *** [modules] Error 2

I have tried to solve this problem for around 2 days now but i can't seem to solve it.
