# Building
goatd builds with Cargo. Its FlowCutter backend is C++ and needs a C++20
compiler; there are no CMake or system-library dependencies.
```sh
cargo build
cargo test --all-targets
```
On Linux `build.rs` tries `g++-14`, `g++-13`, `g++-12`, and then `g++`; on
macOS and Windows it uses the platform compiler (Apple clang, MSVC). Set
`GOATD_CXX` to use another GCC 12-or-newer compiler or a recent Clang:
```sh
GOATD_CXX=clang++ cargo build
```
The minimum supported Rust version is recorded as `rust-version` in
`Cargo.toml`.
