Thanks poma, I thought that might be the case. I already have the source in a permanent location, I'll also place a text file in there with these instructions so I don't forget. Is the updates directory the location the default location for depmod and modprobe? If a make install is done that places the ko file much deeper in the directory path in a wireless subdirectory. Is there any possibility that this driver will make it into the kernel by default, or is the chipset too new with insufficient usage for that to happen?On 17.01.2015 04:02, Stephen Morris wrote:On 01/16/2015 08:38 AM, Stephen Morris wrote:On 01/15/2015 11:46 PM, poma wrote:On 15.01.2015 08:50, Stephen Morris wrote:I have a driver for a wifi usb device that I need to compile because there are no drivers in the kernel, which has been obtained from the vendor of the device. When I attempt to compile the code the compile fails on the grounds that some warnings are being translated into errors. From my perspective these errors should not be happening because, when a debugging module wants to time stamp the build, that is not an error and is perfectly acceptable.

The git source might be better than what I have at the moment as the vendor source I have seems to be requiring kernel config parameters that appear to not be active in the kernels I am using.I've compiled the code and after copying the compiled module and running the modprobe the device immediately connected. I'll run a few more tests and try a reboot to see if it still works successfully. I am assuming that I will need to perform all these steps everytime the kernel is upgraded, would that be correct?If you put the source code on a permanent location, this part of the procedure is necessary for a new i.e. an upgraded kernel: $ cd /path/to/rtl8812au/ $ make clean $ make $ su # cp 8812au.ko /lib/modules/$(uname -r)/updates/ # depmod # modprobe -v 8812au
