# \*-unknown-freebsd
|
||||
|
||||
**Tier: 2/3**
|
||||
|
||||
[FreeBSD] multi-platform 4.4BSD-based UNIX-like operating system.
|
||||
|
||||
## Target maintainers
|
||||
|
||||
- Alan Somers `asomers@FreeBSD.org`, https://github.com/asomers
|
||||
- Mikael Urankar `mikael@FreeBSD.org`, https://github.com/MikaelUrankar
|
||||
|
||||
## Requirements
|
||||
|
||||
The `x86_64-unknown-freebsd` target is Tier 2 with host tools.
|
||||
`i686-unknown-freebsd` is Tier 2 without host tools. Other targets are Tier 3.
|
||||
See [platform-support.md](../platform-support.md) for the full list.
|
||||
|
||||
We commit that rustc will run on all currently supported releases of
|
||||
[FreeBSD][supported-releases] . EoL releases may be supported for a time, too.
|
||||
The same guarantees apply for the standard library and the libc crate.
|
||||
|
||||
Specific release support matrix, as of Rust 1.82.0:
|
||||
|
||||
| FreeBSD Release | rustc | std | libc |
|
||||
| --------------- | -------- | -------- | ------- |
|
||||
| 10 | < 1.78.0 | ? | ? |
|
||||
| 11 | < 1.78.0 | < 1.78.0 | current |
|
||||
| 12+ | current | current | current |
|
||||
|
||||
`extern "C"` uses the official calling convention of the respective
|
||||
architectures.
|
||||
|
||||
FreeBSD OS binaries use the ELF file format.
|
||||
|
||||
## Building Rust programs
|
||||
|
||||
The `x86_64-unknown-freebsd` and `i686-unknown-freebsd` artifacts are
|
||||
distributed by the rust project and may be installed with rustup. Other
|
||||
targets are built by the ports system and may be installed with
|
||||
[pkg(7)][pkg] or [ports(7)][ports].
|
||||
|
||||
By default the `i686-unknown-freebsd` target uses SSE2 instructions. To build
|
||||
code that does not require SSE2, build lang/rust from [ports][ports] and
|
||||
disable the `SSE2` option at build time. That will produce non-compliant
|
||||
behavior. See [issue #114479][x86-32-float-issue].
|
||||
|
||||
## Testing
|
||||
|
||||
The Rust test suite can be run natively. It can also be run from the FreeBSD
|
||||
ports tree with the `make test` command from within the lang/rust directory.
