Has anyone successfully compiled Android 12?

#1

I used rock5c and referred to the Low-Level development documents of 5B and 5C

My system is Ubuntu 22.04.4, and I created a docker environment to compile Android 12.

Current problem is that the kernel cannot be compiled, and the error is as follows:

make: *** [arch/arm64/Makefile:214: rk3588s-rock-5c.img] Error 2

failed to build some targets (04:19 (mm:ss))

I thought it was a problem with the lz4 version, so I updated to the latest lz4. But I still couldn’t compile the kernel.

Can anyone give me some hints?Thanks

Resolved,Radxa’s 5C documentation gives severely incomplete dependencies. There is no need for docker, direct compilation is more efficient

well i finally find the reason. when generating kernel/kheaders_data.tar.xz, cpio is needed.
