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 for the full list.
We commit that rustc will run on all currently supported releases of FreeBSD . 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) or ports(7).
By default the i686-unknown-freebsd target uses SSE2 instructions. To build
code that does not require SSE2, build lang/rust from ports and
disable the SSE2 option at build time. That will produce non-compliant
behavior. See issue #114479.
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.
