Host Build (arm64)

You can build the RaspberryPi executable using the host itself.

This is very slow and may lead the RaspPi to become unresponsive while downloading and/or installing Go packages and likely run out of memory which will cause things to grind to a halt.

The following top shows that the RaspPi system with 1GB RAM has effectively run out of resources while installing go install github.com/gohugoio/hugo@v0.101.0…

To mitigate locking up the RaspPi during this build it is possible to restrict the resources for Go.

GOMEMLIMIT=500MiB GOMAXPROCS=2 make with-deps -j 1

The following script will download the miminim required versions of nodejs, npm and golang. It will probably run on a RaspPi 4 with ~4GB+ RAM.
