Building HenLoader on Debian

Prerequisites

Install the required build tools and libraries:

sudo apt update
sudo apt install -y build-essential make pkg-config libbsd-dev

JDK Packages

The Makefile expects JDK 8 and JDK 11 packages in the thirdparty/ directory with specific filenames. The exact versions specified in the Makefile may not be available, but compatible versions can be downloaded and renamed.

For x86_64 (amd64):

The packages should be named:

OpenJDK8U-jdk_x64_linux_hotspot_8u462b08.tar.gz
OpenJDK11U-jdk_x64_linux_hotspot_11.0.28_6.tar.gz

You can download compatible versions and rename them, or use these commands:

cd thirdparty
wget -O OpenJDK8U-jdk_x64_linux_hotspot_8u462b08.tar.gz \
  "https://github.com/adoptium/temurin8-binaries/releases/download/jdk8u472-b08/OpenJDK8U-jdk_x64_linux_hotspot_8u472b08.tar.gz"
wget -O OpenJDK11U-jdk_x64_linux_hotspot_11.0.28_6.tar.gz \
  "https://github.com/adoptium/temurin11-binaries/releases/download/jdk-11.0.29%2B7/OpenJDK11U-jdk_x64_linux_hotspot_11.0.29_7.tar.gz"

For aarch64 (ARM64):

Similar approach - download compatible versions and rename to match the Makefile's expected filenames.

Building

Simply run:

make

This will:

Extract JDK 8 from the tarball
Build the makefs tool
Compile the Java sources
Sign the JAR files
Assemble the Blu-ray disc structure
Create the final ISO: build/henloader.iso

Cleaning

To clean build artifacts:

make clean
