Requirements

Building the target itself requires a RISC-V compiler that is supported by cc-rs.

Building the target

The target can be built by enabling it for a rustc build.

[build]
target = ["riscv64gc-unknown-linux-musl"]

Make sure your C compiler is included in $PATH, then add it to the config.toml:

[target.riscv64gc-unknown-linux-musl]
cc = "riscv64-linux-gnu-gcc"
cxx = "riscv64-linux-gnu-g++"
ar = "riscv64-linux-gnu-ar"
linker = "riscv64-linux-gnu-gcc"

Building Rust programs

This target are distributed through rustup, and otherwise require no special configuration.

Cross-compilation

This target can be cross-compiled from any host.

Testing

This target can be tested as normal with x.py on a RISC-V host or via QEMU emulation.
