I’m new to rust development so maybe I’m missing something basic here, but I’m having trouble getting redox built on macOS (10.12.3 sierra) by following the steps in the readme.
I used rustup to get nightly installed:
rustc 1.16.0-nightly (df8debf6d 2017-01-25)
make output below:
make all
mkdir -p build/userspace
RUSTC="./rustc.sh" RUSTDOC="./rustdoc.sh" cargo rustc --manifest-path rust/src/libstd/Cargo.toml --features "panic-unwind" --target x86_64-unknown-redox --release -- -C codegen-units=`nproc` -L native=libc-artifacts/usr/lib -o build/userspace/libstd.rlib
