Compilied it for RPi Zero ( CONFIG_PLATFORM_I386_PC = n, CONFIG_PLATFORM_ARM_RPI = y, CONFIG_PLATFORM_ARM_RPI3 = n ) successfully but it is not working.
Dmesg output after installing it:

Will try different settings, but would be good if more people could share their experiences in trying to use this with a RPi 0 ( or other ARM11 device ). Just to know if this more than just a compile issue. :/
Ok... recompiled this ( no DKMS ) and now the driver seems to be working. The warning no longer shows up in dmesg. Having said that, I am still working on some issues...
I am using the RPi 0 W as an wireless access point ( wlan0 AP, wlan1 client). My intent is to replace the older wireless adapter I was using with a new one. After replacing it and installing the driver, I was no longer able to use wpa_supplicant. I had to edit the /etc/network/interfaces.d file ( add information for wlan1 ) and do 'ifdown' and 'ifup' to get the new adapter to be configurable by wpa_supplicant. After this, I am now able to use wpa_supplicant to connect to a network but I am no longer able to forward traffic between wlan0 and wlan1 for some reason...
All of this might not be directly related to the driver but just leaving this information to give a heads up that using an RTL8821CU adapter with a RPi 0 W is still not straightforward. Other adapters ( preferably ones with OOTB support or at least with debian driver packages available ) will be a better choice... :/
Same issue here, I have a PiZero V1.3 from 2015. carlosanunes, did you change anything before recompiling? I started with the "make; make install; modprobe" way...
No, did not perform any changes. Just 'sudo make' and 'sudo make install' in a fully updated system. After that, just rebooting. No errors in dmesg after that.
Hmmm I actually get a compile warning, and error, and finishes with that error, step 2, I think. Uuuugghhh been through so many truing to get these adapters to work.
Should this driver work on Buster , on a Zero, older version ?
