error: linking with rust-lld failed

[ajadavis]

following along edition 2, and currently finishing "minimal-rust-kernel"

getting this error when running "cargo bootimage":

"error: linking with rust-lld failed: exit status: 1:

when i run "rustc --version" i get output:
"rustc 1.66.0-nightly (db0597f56 2022-10-11)"

so i think the nightly build setting is ok.

contents of ./.cargo/config.toml:

[unstable]
build-std-features = ["compiler-builtins-mem"]
build-std = ["core", "compiler_builtins"]

[build]
target = "x86_64-blog_os.json"

contents of "x86_64-blog_os.json":

{
  "llvm-target": "x86_64-unknown-none",
  "data-layout": "e-m:e-i64:64-f80:128-n8:16:32:64-S128",
  "arch": "x86_64",
  "target-endian": "little",
  "target-pointer-width": "64",
  "target-c-int-width": "32",
  "os": "none",
  "executables": true,
  "linker-flavor": "ld.lld",
  "linker": "rust-lld",
  "panic-strategy": "abort",
  "disable-redzone": true,
  "features": "-mmx,-sse,+soft-float"
}

i've got "bootloader = "0.9.8"" as a dependency in Cargo.toml (running v 10 gave issues before, but following along the blog's version now seems ok.

im on macOS Monterey v12.5
chip is an M1 max

doing some more research into rust-lld, but couldn't find anything in first pass. next step is to learn more about rust-lld from ground up. thx in advance if anyone knows the issue!

I'm seeing the same issue. Here's the full error output:

Should already be fixed, the boot loader build is green again too, try again after upgrading to the latest nightly

[ajadavis]

Incredible. Working for me after upgrading to latest nightly- many thanks!
