# Native ARM 32-Bit OpenJDK Builds

I'm running OpenJDK builds on 32-bit Raspberry Pis for fun since

many years and discovered [several issues](https://bugs.openjdk.org/browse/JDK-8312366?jql=reporter%20%3D%20%27marchof%27%20AND%20summary%20~%20%27arm32%27).

This repository uses [GitHub Actions](https://github.com/features/actions) with

the [qemu](https://www.qemu.org/) emulator to create native 32-bit builds on RaspiOS.

The build time on the emulator is about 2 hours, in comparison to 40 minutes on an actual Raspberry Pi 4.

**⚠️ Published artifacts are completely untested. Use as your own risk!**

Better sources for ARM 32-bit OpenJDK builds are:

* [Bellsoft's Liberica JDK](https://bell-sw.com/pages/downloads/)

* [Mister Shipilëv's Home for Peculiar (JVM) Builds](https://builds.shipilev.net/)

## Build Steps

* Checkout OpenJDK source tree

* Run RaspiOS emulator with `qemu`

* Install build dependencies

* Install bootstrap JDK

* Run `configure`

* Run `make images`

* Zip JDK and upload to action
