I'm trying to compile the driver of rtl8812AU (github.com/diederikdehaas/rtl8812AU).
I've downloaded and installed the last version of raspbian.
The following is written in the change log, among others:
2016-09-23:
* Updated firmware and kernel (github.com/raspberrypi/firmware/commit/ad8608c08b122b2c228dba0ff5070d6e9519faf5)
I know I need the headers of the kernel to compile the module:
mkdir /usr/src/firmware && cd /usr/src/firmware
git clone https://github.com/raspberrypi/firmware
git checkout ad8608c08b122b2c228dba0ff5070d6e9519faf5
cat /usr/src/firmware/git_hash
which gives me 2d31cd571e6f2ac61a3eda273d973058e1bb1f58
mkdir /usr/src/linux && cd /usr/src/linux
git clone https://github.com/raspberrypi/linux
git checkout 2d31cd571e6f2ac61a3eda273d973058e1bb1f58
Now I'm not sure how to proceed anymore. I've tried building the module with DKMS but I couldn't manage to let 'dkms build' pass the right ARCH to 'make'. It executes 'make ARCH=armv7l', but there's no folder /usr/src/linux/arch/armv7l. It should be looking into /usr/src/linux/arch/arm. I've asked a question on stack overflow about this problem.
Since DKMS is not on my side now want to build the module by evoking 'make' directly. So now I executed:
sudo make ARCH=arm64 CROSS_COMPILE= -C /lib/modules/4.4.21-v7+/build M=/var/lib/dkms/rtl8812AU/4.3.14/build modules
make: Entering directory '/usr/src/linux'
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.WARNING: Symbol version dump ./Module.symvers
is missing; modules will have no dependencies and modversions.Building modules, stage 2. scripts/Makefile.modpost:42: include/config/auto.conf: No such file or directory
How to proceed?
