Known Issues

Rust 1.90 / x86_64-unknown-linux-gnu

Linking with rust-lld fails with unresolved symbols. As a workaround add the following entry to your .cargo/config.toml:

[target.x86_64-unknown-linux-gnu]
rustflags = ["-Clinker-features=-lld"]

Alternatively set the corresponding environment variable CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUSTFLAGS to -Clinker-features=-lld.
