[paandahl]

I think there has been a slight breaking change in the Rust compiler. I had the same problem and was able to work around it by changing from "ld.lld" to "ld" within the "pre-link-args"-section of:

/home/vishwak/.cargo/registry/src/github.com-1ecc6299db9ec823/bootloader-0.9.23/x86_64-bootloader.json

[KurlykovDanila]

I also encountered the same problem in rustc 1.66.0-nightly. I was helped by rolling back to the version (nightly-2022-07-15-x86_64), rustc 1.64.0-nightly

[phil-opp]

Thanks for reporting! This appears to be an accidental regression in rustc, which is going to be fixed by rust-lang/rust#102836. Until then, staying on an older nightly is probably the best workaround for now.

See also rust-osdev/bootloader#271.

[phil-opp]

This should be fixed on the latest Rust nightlies.
