# Building
|
|
|
|
## Go
|
|
|
|
Requires Go 1.24 or later.
|
|
|
|
```bash
|
|
go build -o softether-go ./cmd/softether-go/
|
|
```
|
|
|
|
### Static binary
|
|
|
|
For deployment in minimal containers (Alpine, scratch) or systems without glibc:
|
|
|
|
```bash
|
|
CGO_ENABLED=0 go build -o softether-go ./cmd/softether-go/
|
|
```
|
|
|
|
### Cross-compilation
|
|
|
|
```bash
|
|
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o softether-go ./cmd/softether-go/
|
|
CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -o softether-go ./cmd/softether-go/
|
|
```
|
|
|
|
Only Linux targets are supported (the TAP device interface uses Linux-specific ioctls).
|
|
|
|
## Nix
|
|
|
|
Build with the flake:
|
|
|
|
```bash
|
|
nix build
|
|
```
|
|
|
|
The result is in `./result/bin/softether-go`.
|
|
|
|
Enter a development shell with Go tooling:
|
|
|
|
```bash
|
|
nix develop
|
|
```
|
|
|
|
Build within the dev shell:
|
|
|
|
```bash
|
|
nix develop -c bash -c 'go build -o softether-go ./cmd/softether-go/'
|
|
```
|
|
|
|
## Dependencies
|
|
|
|
The only Go dependency is `golang.org/x/sys` for Linux syscall constants (TUN/TAP ioctls). Dependencies are vendored in `vendor/`.
|
|
|
|
At runtime, the only external dependency is `ip` (iproute2) for route and address management.
