Failed to build kernel

[rpashkoff]

I configured build environment in Docker using Dockerfile from manual and proceed with Quick start steps (https://bupt-os.github.io/website/docs/introduction/quick-start/). On Compile Kernel Step (4) I got the following error:

  RUSTC L rust/build_error.o

error: aborting due to 2 previous errors

kindly ask to help to resolve it

It seems the .config file is not correctly configured. You can have the right .config with make LLVM=1 rros_defconfig.
