Trying to compile this for the Edimax N150 2-in-1 WiFI/Bluetooth Adapter (EW-7611ULB) on a new Debian image from beagleboard.org. Clone the repo and ran make. Below was the output.

ps@beaglebone:~/rtl8723bu$ make

The drivers supplied by Edimax resulted in similar errors, but looking at this repo I thought there might be some more recent developments for it. Any thoughts?

gregmihalko commented 5 years ago

Should I try to run sudo apt-get install linux-headers-$(uname -r) and re-try running make again?

lwfinger commented 5 years ago

I'm not sure that you have the correct apt-get packages, but you do not have the kernel headers installed. That is why you are getting the error.

gregmihalko commented 5 years ago

Thanks @lwfinger does that line above look correct? If so, I will run that and post the results.

No dice. Here's what I got:

You need to find out the steps in preparing builds for out-of-kernel modules from your distro. If you were using openSUSE, I could help, but not for any .deb distro.

gregmihalko commented 5 years ago

Got it - where would I start to find that info? Would it be something that could be incorporated back into this repo? If we ended up with good documentation, this adapter would be an awesome addition to standard BBB iot stacks!

Search for "building external modules" or "kernel headers" for your distro. Alternatively, you might check the forums of your distro. There should not be a difference between X86 and ARM.
