Compiled Rust Toolchain for RV32E

This repository compiles and publishes as release final binaries of the Rust toolchain targeting RISC-V RV32E.

Building

./clone.sh
./patch.sh
./build.sh
./package.sh

Executing those steps will create a rust-rve-nightly-$rust_commit_date-$TOOLCHAIN_HOST_TRIPLET.xz in your working directory. See the next chapter about installation how to use this toolchain with rustup.

Installation

You can either download a package from the release page or build it yourself with the instructions above. The following steps will make the toolchain available via rustup's +rve-nightly syntax.

tar --zstd -xf rust-rve-nightly-$rust_commit_date-$TOOLCHAIN_HOST_TRIPLET.xz
mv rve-nightly ~/.rustup/toolchains/
# Clear the "downloaded" attribute recursively on macOS to satisfy GateKeeper
xattr -rc ~/.rustup/toolchains/rve-nightly

The last step is needed when downloading the binary toolchain with Safari. Otherwise GateKeeper will prevent running downloaded binaries without code signature:
