@ -15,27 +15,35 @@ This target is cross-compiled. There are no special requirements for the host.
Motor OS uses the ELF file format.
## Building the target
## Building the target toolchain
The target can be built by enabling it for a `rustc` build, for example:
Motor OS target toolchain can be
[built using `x.py`](https://rustc-dev-guide.rust-lang.org/building/how-to-build-and-run.html):
The bootstrap file:
```toml
[build]
build-stage = 2
target = ["x86_64-unknown-motor"]
host = ["x86_64-unknown-linux-gnu"]
target = ["x86_64-unknown-linux-gnu", "x86_64-unknown-motor"]
```
The build command:
```sh
./x.py build --stage 2 clippy library
```
## Building Rust programs
Rust standard library is fully supported/implemented, but is not yet part of
the official Rust repo, so an out-of-tree building process should be
followed, as described in the
[build doc](https://github.com/moturus/motor-os/blob/main/docs/build.md).
See the [Hello Motor OS](https://github.com/moturus/motor-os/blob/main/docs/recipes/hello-motor-os.md)
example.
## Testing
Cross-compiled Rust binaries and test artifacts can be executed in Motor OS VMs,
as described in e.g.
as described in the [build doc](https://github.com/moturus/motor-os/blob/main/docs/build.md)
and the
[Hello Motor OS](https://github.com/moturus/motor-os/blob/main/docs/recipes/hello-motor-os.md)
example.
