how to build on beagle bone black

[mogar]

Hi,

I'm trying to build this on a BBB. I have cloned the repo, but trying to make it gives me an error:

root@beaglebone:~#git clone https://github.com/lwfinger/rtl8723bu.git
root@beaglebone:~#cd rtl8723bu
root@beaglebone:~/rtl8723bu# make
make ARCH=armv7l CROSS_COMPILE= -C /lib/modules/3.14.46-ti-r70/build M=/root/rtl8723bu modules
make[1]: Entering directory `/lib/modules/3.14.46-ti-r70/build'
make[1]: *** No rule to make target `modules'.  Stop.
make[1]: Leaving directory `/lib/modules/3.14.46-ti-r70/build'
make: *** [modules] Error 2
root@beaglebone:~/rtl8723bu#

What is the proper way to build this?

You are missing the kernel headers.

Thanks for your advice! I installed the headers.

I then had to change the SUBARCH option in the Makefile to arm in order for it to find the correct directory in the headers.

I then tried to make it, but got the following error:

Sorry it took so long to get to this problem. I think there was an error in the logic that should now be fixed. Please repull.

Looks like that worked. Thanks for your help!
