Using RaspberryPi2 @ OSMC, I am trying to plug in my WiFi+BT stick:

osmc@osmc:~/drv/rtl8723bu$ uname -a Linux osmc 4.4.27-2-osmc #1 SMP PREEMPT Sun Oct 30 16:33:55 UTC 2016 armv7l GNU/Linux

osmc@osmc:~/drv/rtl8723bu$ lsusb Bus 001 Device 005: ID 0bda:b720 Realtek Semiconductor Corp. Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.

Getting same error that many people had:

osmc@osmc:~/drv/rtl8723bu$ make make ARCH=arm CROSS_COMPILE= -C /lib/modules/4.4.27-2-osmc/build M=/home/osmc/drv/rtl8723bu modules make[1]: *** /lib/modules/4.4.27-2-osmc/build: No such file or directory. Stop. Makefile:321: recipe for target 'modules' failed make: *** [modules] Error 2

Getting headers and linking them:

sudo apt-get install rbp2-headers-4.4.27-2-osmc sudo ln -s /usr/src/rbp2-headers-4.4.27-2-osmc/ /lib/modules/4.4.27-2-osmc/build

Getting past that error and to the new one. Sorry, can't copypaste exact output right now, it was about missing file <mach/memory.h>

find /usr/src/ -iname "memory.h"

Copying missing mach/memory.h from /usr/src/rbp2-headers-4.4.27-2-osmc/arch/arm/mach-bcm2709/include/mach/ and trying again. Same error about missing <mach/io.h> - doing the same thing and trying again:

at this point, I am completely exhausted and desperate. Please help?

OK, got it myself: do not link installed headers, instead move them: sudo mkdir /lib/modules/4.4.27-2-osmc/build sudo mv /usr/src/rbp2-headers-4.4.27-2-osmc/* /lib/modules/4.4.27-2-osmc/build/
