Tier: 2/3

Targets for the Redox OS operating system.

Target triplets available so far:

  • x86_64-unknown-redox (tier 2)
  • aarch64-unknown-redox (tier 3)
  • i686-unknown-redox (tier 3)

Target maintainers


These targets are natively compiled and can be cross-compiled. Std is fully supported.

The targets are only expected to work with the latest version of Redox OS as the ABI is not yet stable.

extern "C" uses the official calling convention of the respective architectures.

Redox OS binaries use ELF as file format.

Building the target

You can build Rust with support for the targets by adding it to the target list in config.toml. In addition a copy of relibc needs to be present in the linker search path.

Building Rust programs and testing

Rust does not yet ship pre-compiled artifacts for Redox OS except for x86_64-unknown-redox.

The easiest way to build and test programs for Redox OS is using redoxer which sets up the required compiler toolchain for building as well as runs programs inside a Redox OS VM using QEMU.

Cross-compilation toolchains and C code

The target supports C code. Pre-compiled C toolchains can be found at https://static.redox-os.org/toolchain/.
