Build from source on arm64 - documentation and go bug

[davekempe]

Describe the bug

Build from source fails on arm64 with a go error. I believe related to a go bug in 1.18.4. Trying to get icingadb going on m1 mac.
I wanted to make a ticket about building from source in general too. I found the command line in the icingadb-docker repo:

So this bug is really a few things -
1 what is the correct way to build from source.
2 Will this work on arm64 or are there packages for arm64 in the works?
3 To track when the go bug is fixed (probably in 1.18.5)

# github.com/icinga/icingadb/pkg/com
pkg/com/bulker.go:30:16: internal compiler error: assertion failed

Please file a bug report including a short program that triggers the error.

To Reproduce

Provide a link to a live example, or an unambiguous set of steps to reproduce this bug. Include configuration, logs, etc. to reproduce, if relevant.

1. go version
   go version go1.18.4 linux/arm64
2. git clone https://github.com/Icinga/icingadb.git
3. cd icingadb
4. go build -ldflags '-s -w' ./cmd/icingadb

quits with internal compiler error.

github.com/icinga/icingadb/pkg/com

pkg/com/bulker.go:30:16: internal compiler error: assertion failed

Expected behavior

Icingadb binary is built, and ready to use.

Your Environment

This is debian 11 on arm64.

Include as many relevant details about the environment you experienced the problem in

• Icinga DB version: 1.0
• Icinga 2 version: 2.11
• Operating System and version: Debian 11 on arm64 (parallels on macos, but can be baremetal soon)

Yes, that's an issue in Go 1.18.4: golang/go#53762

Also not specific to arm64, we're seeing the same behavior on amd64.

There is not much we can do here, either wait for Go 1.18.5 (which will hopefully include a fix: golang/go#53274) or use 1.18.3 for now.

Regarding documentation on how to build from source: Just standard go build combined with the somewhat common cmd subdirectory in Go projects will do the job, linker flags in the docker build are just there to keep the size of the image smaller. But I do understand that you don't necessarily have to be familiar with the language just to build some software from source.

[davekempe]

Thanks. A quick note in the Readme or similar for building from source may help the noobs like me then. Probably can close this off - if nothing else it may help someone searching this repo.

@julianbrost FYI this will not be fixed in 1.18 per the bug report you linked to.
