Can't install bootimage about bootimage HOT 10 CLOSED

but are you going to continue writing the tutorial?

It's difficult to guess without the actual errors, but the problem might be that you're running the cargo install command from a folder that contains a .cargo/config.toml file with build-std settings. If that's the case, try running it again from a parent directory or from your home directory.

If I run cargo install bootimage on C: I get this error

Two things:

• You probably don't want to set any unstable features in the .cargo/config.toml in your user directory since these settings will then be used for all your Rust projects. Instead, create a local .cargo/config.toml file in your project directory. For details, see https://doc.rust-lang.org/cargo/reference/config.html#hierarchical-structure.
• It looks like you're using a nightly from 2020, which is way to old. Try running rustup update.

It now installs but the bin file has no extension and when I run it in qemu nothing happens.

Which bin file are you talking about?

I'm following your tutorial on how to create a operating system in rust. edition-2, A Minimal Rust Kernel

from bootimage.

Does the cargo bootimage command work? If so, what error occurs when you're trying to start the bootimage-blog_os.bin in QEMU?

from bootimage.

thanks it's now working

from bootimage.

Great to hear that it's working now!

but are you going to continue writing the tutorial?

I'm planning to create a new third edition, which will do some things a bit differently (bootimage is no longer needed, support for UEFI booting, APIC instead of PIC, etc.).
