Won't compile on Buster (Raspberry PI)

[jonathan84clark]

I am trying to build this driver on my Raspberry PI 3 compute module. Here are the results of that:

1. git clone https://github.com/quickreflex/rtl8188eus
2. cd rtl8188eus/
3. make all

Here is the error I am seeing:
bin/sh: 1: bc: not found
make ARCH=armv7l CROSS_COMPILE= -C /lib/modules/5.10.103-v7+/build M=/home/pi/BuildDir/rtl8188eus modules
make[1]: *** /lib/modules/5.10.103-v7+/build: No such file or directory. Stop.
make: *** [Makefile:1911: modules] Error 2

Any help on this would be great!

Thanks,

Jonathan L Clark

I believe u can solve this by installing the linux kernel headers...
