I was writing and building Rust lang last week. I am running rustc 1.54.0 (a178d0322 2021-07-26)
Suddenly I started getting link errors on the hello world propgram created by cargo.
davidtilley@Davids-MacBook-Pro learn % cargo new hw
Created binary (application) `hw` package
davidtilley@Davids-MacBook-Pro learn % cd hw
davidtilley@Davids-MacBook-Pro hw % cargo build --verbose
Compiling hw v0.1.0 (/Users/davidtilley/dev/rust/learn/hw)
Running `rustc --crate-name hw --edition=2018 src/main.rs --error-format=json --json=diagnostic-rendered-ansi --crate-type bin --emit=dep-info,link -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 -C metadata=d324b43638469752 --out-dir /Users/davidtilley/dev/rust/learn/hw/target/debug/deps -C incremental=/Users/davidtilley/dev/rust/learn/hw/target/debug/incremental -L dependency=/Users/davidtilley/dev/rust/learn/hw/target/debug/deps`
