# `*-wrs-vxworks`
2+
3+
**Tier: 3**
4+
5+
Targets for the VxWorks operating
6+
system.
7+
8+
Target triplets available:
9+
10+
- `x86_64-wrs-vxworks`
11+
- `aarch64-wrs-vxworks`
12+
- `i686-wrs-vxworks`
13+
- `armv7-wrs-vxworks-eabihf`
14+
- `powerpc-wrs-vxworks`

20+
21+
## Requirements
22+
23+
Rust for each target can be cross-compiled with its specific target vsb configuration. Std support is added but not yet fully tested.
24+
25+
## Building the target
26+
27+
You can build Rust with support for the targets by adding it to the `target` list in `config.toml`. In addition the workbench and wr-cc have to configured and activated.
28+
29+
```toml
30+
[build]
31+
build-stage = 1
32+
target = [
33+
"<HOST_TARGET>",
34+
"x86_64-wrs-vxworks",
35+
"aarch64-wrs-vxworks",
36+
"i686-wrs-vxworks",
37+
"armv7-wrs-vxworks-eabihf",
38+
"powerpc-wrs-vxworks",
39+
"powerpc-wrs-vxworks-spe",
40+
]
41+
```
42+
43+
## Building Rust programs
44+
45+
Rust does not yet ship pre-compiled artifacts for VxWorks.
46+
47+
The easiest way to build and test programs for VxWorks is to use the shipped rustc and cargo in VxWorks workbench, following the official windriver guidelines.
48+
49+
## Cross-compilation toolchains and C code
50+
51+
The target supports C code. Pre-compiled C toolchains can be found in provided VxWorks workbench.
