Yes, it doesn't work with the latest Rust compiler. I will update the kernel.

which rust version can build and run this os??

jounathaen commented 3 years ago

The last commit in this repo was on the 06.02.2021. Maybe you try the nightly from that day or a few days earlier

Hi,

Just to piggyback on this: Yes, you cannot run the project on any newer nightly build of rust. You'll need an older toolchain such as nightly-2021-02-01-x86_64-unknown-linux-gnu for it to compile. The newer one, even with a few corrections, returns several assembler errors due to an llvm bug (I will update issue #12 regarding this).
