I’m evaluating Linux Mint as a main OS replacement, so I’m trying to get my stuff (building) and running on it.
Part of it is building then running OpenJDK and OpenJFX.

First OpenJDK:

1. Install the dependencies for OpenJDK

sudo apt install git

the boot JDK

sudo apt install openjdk-25-jdk

the JDK build dependencies

sudo apt-get install autoconf
sudo apt install libasound2-dev
sudo apt install libcups2-dev
sudo apt install libfontconfig1-dev
sudo apt install libx11-dev libxext-dev libxrender-dev libxrandr-dev libxtst-dev libxt-dev

2. Get the code

mkdir ~/dev
cd ~/dev
git clone https://github.com/openjdk/jdk

3. Time to build

cd ~/dev/jdk
bash configure --with-boot-jdk=/usr/lib/jvm/java-25-openjdk-amd64 --with-vendor-name=LH --with-vendor-url=https://lhochet.dev --with-version-build=5
make images

Then OpenJFX:

This blog has moved again, now the code is in Gitea and served on a VPS.

The JDK has just moved to GitHub through project Skara. I am moving to a new laptop. So it is time to revisit building OpenJDK and OpenJFX (on Windows 10 64bits).

1. Create a C:\dev\ directory 

2. Download and install Cygwin
   select the following packages

   • autoconf

   • make

   • zip

   • unzip

3. Download and install Git

   Either from Git for Windows or via Cygwin (the later may be more compatible with the build)

4. Download the current OpenJDK and extract it to C:\dev\jdk-14.0.2

Time for a new blog.
When I started, Blogger was fine.
However adding code/commands snippets is not built-in, and it lacks modifications history.
So I am now moving to a Hugo blog hosted at GitLab: https://blog.lhochet.dev

public class Main
{
  public static void main(String[] args)
  {
    System.out.println("Hello new blog!");
  }
}

I’ll leave the old blog as a backup, though I’ve migrated the old articles to the new blog for convenience and to see how Hugo handles real articles.

I like widget bars (if only because they tend to provide an analogue clock that I consult occasionally),
so over time I’ve used AB5k (Glossitope), WidgetFX, then Google Desktop, when the later was discontinued I thought I should do my own, so that it would only be discontinued when I’d stop maintaining it myself.
Eventually I started working on one using JavaFX.
Since I could not find a ‘proper’ way to have a side bar, I tried with this project to add some AppBar (doc and Petzold’s article on the subject) support to OpenJFX.
It currently supports adding a main window that is an AppBar on any of the 4 edges, resizing and transparency.

Thanks to Andrew Luo (and the JDK build team), it is now possible to build OpenJDK with Windows Subsystem for Linux on Windows 10 (1809+). This post will also use the JDK mirror at Github (if it is not synchronised, see the previous post for using Mercurial).

2019-01-19: added the Mercurial instructions

1. Activate Windows Subsystem for Linux
   In an administrative Powershell:

   Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

   Restart then install, say, Ubuntu from the Windows Store

A lot has changed in the last year when it comes to building OpenJDK and OpenJFX on Windows (10 64bits) (single repository, integrated Freetype, VS2017)… and some more changes are expected with project Skara.

In the mean time here are some updated steps:

Update: 2018-08-18: VS2017 15.8 broke the OpenJFX build, updated the steps with an additional one to work around this issue.

1. Create a C:\dev\ directory 

2. Download and install 7-zip (if needed, to open .tar.gz and  .xz files)

Wanting to test Windows Subsystem for Linux, I’ve refreshed my steps for building on Ubuntu.
(Dependencies come from the helpful configure messages for the JDK and from the OpenJFX wiki)

Quick steps for installing WSL:

1. Activate the developer’s mode in settings

2. In an administrator PowerShell console run:

   Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

3. Open Bash and install Ubuntu  (the following also applies to a VirtualBox VM)

To build OpenJFX and OpenJDK 9:

1. Install the dependencies:

Although I have other applications running as Jigsaw modules, I hadn’t migrated WorldClock to it. Now it is.

WorldClock is currently composed of a set of ‘modules’:

• config
  that will read/write a configuration from/to disk

• geonames4lhwc
  that will connect to the Geonames service and retrieve a list of cities for a search string

• application
  the application

• editor
  an editor for the configuration

• panel
  the WorldClock panel that shows the day and night on Earth

This post is a step by step to build the OpenJDK 9 with OpenJFX 9 with the Jigsaw changes on Windows (10 64bits).

It is based on the Jake instructions.

Update: 2017-01-21: OpenJFX has updated build requirements

1. Create a C:\dev\ directory

2. Download and install Visual Studio 2013 Community

   1. Download (it may be faster to download the ISO)

   2. Install

      • uncheck all the options

      • or download

        AdminDeployment.xml

        to C:\dev\temp then start the installation with:
