See [`GOOS` and `GOARCH` environment variable](https://golang.org/doc/install/source#environment) for the list of supported targets. Cross compilation is helpful if you want to build Gitea for less-powerful systems (such as Raspberry Pi). + +To cross build Gitea with build tags (`TAGS`), you also need a C cross compiler which targets the same architecture as selected by the `GOOS` and `GOARCH` variables. For example, to cross build for Linux ARM64 (`GOOS=linux` and `GOARCH=arm64`), you need the `aarch64-unknown-linux-gnu-gcc` cross compiler. This is required because Gitea build tags uses `cgo`'s foreign-function interface (FFI). + +Cross-build Gitea for Linux ARM64, without any tags: + +``` +GOOS=linux GOARCH=arm64 make build +``` + +Cross-build Gitea for Linux ARM64, with recommended build tags: + +``` +CC=aarch64-unknown-linux-gnu-gcc GOOS=linux GOARCH=arm64 TAGS="bindata sqlite sqlite_unlock_notify" make build +``` + +Replace `CC`, `GOOS`, and `GOARCH` as appropriate for your architecture target. |
