drc-mac80211 fails to compile

[Alex Roman Nuñez]

Hi there, i'm trying to get libdrc working on my system, but I can't seem to compile mac80211, this is what I do:

make -C /usr/src/linux-headers-`uname -r`  M=`pwd`  modules

And this is what I get:

make: Entering directory '/usr/src/linux-headers-3.16.0-28-generic'

Is there any way I can fix this issue?

Almost forgot, my kernel version is:

3.16.0-28-generic

I'm on ubuntu 14 64 bits.

Hi Alex,

you should get the sources of your kernel and apply the patch to add the TSF file.

apt-get source --only-source linux
cd linux-3.16.0/net/mac80211
wget -O tsf.patch "https://bitbucket.org/memahaxx/drc-mac80211/commits/4a9823cf2a6733bc15a05cffaebd8850d07451a7/raw/"
patch -p1 < tsf.patch
make -C /usr/src/linux-headers-`uname -r`  M=`pwd`  modules

Hello there thanks for your help, I got the driver working, but now I have the problem that when I use the wpa_supplicant and type in my BSSID and PIN I either get <3>WPS-TIMEOUT Requested operation timed out
or <4>Failed to initiate AP scan, any idea on what can cause this?

Hi Alex,

I'm stuck at the same point, have you found a solution at your problem ?

[Dídac Rodríguez]

Where I supose must apply the patch? To the kernel files or the drc-mac80211 files? I'm using a raspberry pi2 with kernel 4.4.0-1-rpi2 to compile the files but I've only have the header files. I supose I need the kernel source. Do you know where I can find them? I'm trying to get them but I cannot find them anyway..

I believe the headers are different in the net part of the kernel. I have only had success compiling on 3.13.0-29-generic (I'm sure any 3.13 rev would be fine). I have tried compiling on 4.4.0, 4.2.0 and 3.19 as well with no luck. So see if you can find an armhf (I think that's the right rpi3 arch) kernel version 3.13 with source and headers (generic).
