This is an example rust program built for an example embedded riscv64 processor, built by Bazel.

Try it out:

bazel build //prg:my_program

This will download all needed tools, configure them, and run a cross-compiler that will produce a binary that can run on a riscv64 processor in machine mode.

bazel build //prg:disasm

This will compile, but also disassemble the basic program. View the result for example using:

cat bazel-bin/prg/disasm.S

Maintenance

Generate rust-project.json

bazel run @rules_rust//tools/rust_analyzer:gen_rust_project

The above requires the target //:gen_rust_project.

Update Cargo files

This is how to generate new lock files. At the project outset, you must

  1. create the empty files //third_party/cargo:Cargo.lock, and //third_party/cargo:Cargo.Bazel.lock.
  2. Run env CARGO_BAZEL_REPIN=true bazel build //... to initialize the lockfiles.
