  Hello everyone,
  
  I'm trying to cross-compile realtek driver for wifi to buildroot.
  RTL8812AU driver (https://github.com/svpcom/rtl8812au)
  Compiling on Ubuntu 24.04.1 LTS
  
  Command to cross-compile:

  Code: Select all

  make ARCH=arm KSRC=/home/marek/Downloads/luckfox-pico/sysdrv/source/kernel CROSS_COMPILE=/home/marek/Downloads/luckfox-pico/tools/linux/toolchain/arm-rockchip830-linux-uclibcgnueabihf/bin/arm-rockchip830-linux-uclibcgnueabihf- -C /home/marek/Downloads/luckfox-pico/sysdrv/source/kernel/ O=/home/marek/Downloads/source/objs_kernel M=/home/marek/Downloads/rtl8812au modules

  ERROR:

  Code: Select all

  make: Entering directory '/home/marek/Downloads/luckfox-pico/sysdrv/source/kernel'
  make[1]: Entering directory '/home/marek/Downloads/source/objs_kernel'
  
    ERROR: Kernel configuration is invalid.
           include/generated/autoconf.h or include/config/auto.conf are missing.
           Run 'make oldconfig && make prepare' on kernel src to fix it.
  
  /home/marek/Downloads/luckfox-pico/sysdrv/source/kernel/Makefile:672: include/config/auto.conf: No such file or directory
  make[1]: *** [/home/marek/Downloads/luckfox-pico/sysdrv/source/kernel/Makefile:758: include/config/auto.conf] Error 1
  make[1]: Leaving directory '/home/marek/Downloads/source/objs_kernel'
  make: *** [Makefile:185: __sub-make] Error 2
  make: Leaving directory '/home/marek/Downloads/luckfox-pico/sysdrv/source/kernel'

  I've tried other variations of the command but faild in any way.
  Can anyone help me to identify why do I get this error and where should I point for autoconf files in kernel?
  
  BTW I also found this FAQ link:
  https://wiki.luckfox.com/Luckfox-Pico/Luckfox-Pico-FAQ/
  In point 19. there is the same error discussed. But solution doesn't work.
  
  Thank you for any help.
