Headscale can be built from source using the latest version of [Go](https://golang.org) and [Buf](https://buf.build)
(Protobuf generator). See the [Contributing section in the GitHub
README](https://github.com/juanfont/headscale#contributing) for more information.

## OpenBSD

### Install from source

```shell
# Install prerequistes
pkg_add go

git clone https://github.com/juanfont/headscale.git

cd headscale

# optionally checkout a release
# option a. you can find official release at https://github.com/juanfont/headscale/releases/latest

latestTag=$(git describe --tags `git rev-list --tags --max-count=1`)

# copy it to /usr/local/sbin
cp headscale /usr/local/sbin
```

### Install from source via cross compile

```shell
# Install prerequistes
# 1. go v1.20+: headscale newer than 0.21 needs go 1.20+ to compile
# 2. gmake: Makefile in the headscale repo is written in GNU make syntax

git clone https://github.com/juanfont/headscale.git

cd headscale

# optionally checkout a release
# option a. you can find official release at https://github.com/juanfont/headscale/releases/latest
# option b. get latest tag, this may be a beta release
latestTag=$(git describe --tags `git rev-list --tags --max-count=1`)

git checkout $latestTag

make build GOOS=openbsd

# copy headscale to openbsd machine and put it in /usr/local/sbin
```
