rust-toolchain should update

run make sfsimg PREBUILT=1 ARCH=riscv32 Caused by: this version of Cargo is older than the 2021 edition, and only supports 2015 and 2018 editions. Makefile:301: recipe for target 'rcore-fs-fuse' failed

Successfully run after updating the content of rust-toolchain to nightly-2022-06-27.

However, You need to run rustup override nightly-2020-06-04-x86_64-unknown-linux-gnu before running make run ARCH=x86_64 LOG=info You will get the following results

 Finished release [optimized] target(s) in 3m 08s
target/riscv32/release/rcore: 1: target/riscv32/release/rcore: Syntax error: "(" unexpected
Makefile:324: recipe for target 'target/riscv32/release/kernel.img' failed
make: *** [target/riscv32/release/kernel.img] Error 2

if you do not run rustup override nightly-2020-06-04-x86_64-unknown-linux-gnu You will fail

Hi, have you ever met the toolchain version problem while compiling under directory rboot?

in which the toolchain version is nightly-2020-06-04-x86_64-unknown-linux-gnu, I have no idea how to control the dependency version 👀

you can change version in "./rust-toolchain". Just like I said before: Successfully run after updating the content of rust-toolchain to nightly-2022-06-27

oh, that's crazy.

I just tried to switch it to the latest one and got tons of errors...

how did you find the exact version number that works fine?

I'm not quite sure. Perhaps your default version was modified to the old version when you ran an error earlier. You can use the following command to view the current default or override version, switch or delete versions and try again.

~$ rustup toolchain list
nightly-2020-06-04-x86_64-unknown-linux-gnu
nightly-2022-06-27-x86_64-unknown-linux-gnu (default)
