Hello Linux RISC-V 64

This tiny tool lets you print some information from /proc and uname from Linux on RISC-V 64.

Build

Rust Version

You will need Rust and the linker from riscv64-linux-gnu-gcc.

cargo build --release

or zig linker:

cargo install cargo-zigbuild

cargo zigbuild --release

Zig version

You will need Zig

# zig version v0.11 or higher (default self-hosting compiler [stage3]) 
zig build -Doptimize=<mode> -Dtarget=arch-os-libc
# mode = ReleaseSafe|ReleaseFast|ReleaseSmall

# specific target
zig build -Doptimize=<mode> -Dtarget=riscv64-linux -Dcpu=baseline_rv64+v # Allwinner D1

# more features RISC-V: https://github.com/lupyuen/zig-bl602-nuttx/issues/1

# Execute (after builded)
./zig-out/bin/hello-zig
# or run directly (default: host target) 
zig build run -Doptimize=<mode> -Dtarget=riscv64-linux

# all targets
zig targets | jq .libc

Run via cpu
