[chyyuu]

in rcore_plus/user
'RUST_BACKTRACE=1 make sfsimg arch=x86_64'
got error:

and I found the error was from mksfs.

mksfs zip build/x86_64 build/x86_64.img

How to fix it?

ANSWER: update mksfs

git clone https://github.com/wangrunji0408/rcore-fs.git
cd rcore-fs/
cargo build --bin mksfs --features=std
cp target/debug/mksfs ~/.cargo/bin/
cd ../../kernel
make run arch=x86_64

OK!!!

mksfs can be installed by cargo, one command is enough:

cargo install --git https://github.com/wangrunji0408/rcore-fs --features="std" --force
