Hi everyone,
Hi Marlon,
I'm using backports 4.14 to build for a custom kernel 3.14. That
kernel includes the RT2800 wifi driver, and if I configure
backports
with menuconfig to build a newer version of that driver it works
perfectly. However, if I configure backports to build the RTL8821
driver, which my kernel otherwise does not include, the driver
never
gets built and backports shows it as not selected the next time I
run
menuconfig.
Is this expected behaviour? Is there something I can do to force
this
driver to build?
This probably means that your 3.14 kernel doesn't have some of the
dependencies needed by the RTL8821 driver from 4.14. Check the list
of
dependencies for the driver and make sure they are included in your
3.14 kernel.

Hey Luca, thanks for the reply! The requirements in the backports 4.14
menuconfig are listed as follows:
Depends on: WLAN [=y] && WLAN_VENDOR_REALTEK [=y] && RTL_CARDS [=m] &&
m && BP_MODULES [=y] && PCI [=y]
I can find the symbol WLAN_VENDOR_REALTEK in the backports 4.14
menuconfig but not in the 3.14 kernel's menuconfig. Does this mean I
can't use the driver with this kernel?
--
Marlon,
That symbol postdates kernel 3.14. I have no idea if the backports code will
run, or even build, in kernels that old, but I think it would be safe for you to
edit the symbol WLAN_VENDOR_REALTEK out of that "depends on" line in the
configuration menu. At least, that will get you to the next problem. :)
