November ’19 release of OpenJDK 8

icedteaToday, icedtea-3.14.0 was released. IcedTea is a software build framework which allows easy compilation of OpenJDK.

The new IcedTea release will build you the latest Java8:  OpenJDK 8u232_b09. This release syncs the OpenJDK support in IcedTea to the official October 2019 security fixes that Oracle released for Java. The release announcement in the mailing list for distro packagers has details about all the security issues and vulnerabilities that are addressed.

I have built Slackware packages for the new Java 8 Update 232 and uploaded them already. Please upgrade at your earliest convenience. Java is still widespread which makes it a popular target for vulnerability attacks.

Here is where you can download the Slackware packages for openjdk and openjre:

If you want to compile OpenJDK 8 yourself you will need apache-ant as well, but otherwise the openjdk/openjre packages have no external dependencies.

Note about usage:

My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8.

Remember that I release packages for the JRE (runtime environment) and the JDK (development kit) simultaneously, but you only need to install one of the two. The JRE is sufficient if you only want to run Java programs (including Java web plugins). Only in case where you’d want to develop Java programs and need a Java compiler, you are in need of the JDK package.

Enjoy! Eric

Slackware Live Plasma5 edition ISO available (based on liveslak 1.3.3)

Yesterday I uploaded a new DVD-sized ISO for the Plasma5 variant of Slackware Live Edition based on the liveslak scripts version 1.3.3. The ISO contains Slackware-current “Tue Nov 12 23:08:45 UTC 2019” with my KDE-5_19.11 and boots a Linux 4.19.83 kernel.

Download this ISO file slackware64-live-plasma5-current.iso preferably via rsync:// because that allows easy resume if you cannot download the file in one go.

Liveslak sources are maintained in git. The 1.3.3 release has some fixes for PXE booting older hardware.
If you want to read about what the Slackware Live Edition can do for you, check out the official landing page for the project, or any of the articles on this blog that were published later on.

Extensive documentation on how to use and develop Slackware Live Edition (you can achieve a significant level of customization without changing a single line of script code) can be found in the Slackware Documentation Project Wiki.

Have fun!

Plasma 5 for Slackware – November ktown release

Dear all, today I released KDE-5_19.11 and it comes with some upgrades to official Slackware packages. Don’t worry – Pat Volkerding kindly added the shared libraries of the official Slackware packages to aaa_elflibs, so if you have been updating your Slackware-current installation properly then nothing will break when you update Slackware’s exiv2 and LibRaw packages to the newer versions contained in the November release of ‘ktown‘.
Official Slackware package updates for exiv2 and LibRaw will come sometime soon, but it will require Pat to recompile several other packages as well that depend on exiv2 and/or LibRaw. I needed the new exiv2 to compile the latest digikam, so I was pleased with Pat’s cooperation to make this a smooth ‘ktown‘ upgrade for you.

The packages for KDE-5_19.11 are available for download from my ‘ktown‘ repository. As always, these packages are meant to be installed on a full installation of Slackware-current which has had its KDE4 removed first. These packages will not work on Slackware 14.2.

What’s new in the October 2019 release

This month’s KDE Plasma5 for Slackware contains the KDE Frameworks 5.64.0, Plasma 5.17.2 and Applications 19.08.3. All this on top of Qt 5.13.2.

This month’s updates to the ‘deps’ are: qt5 and PyQt5.
Fresh additions are: LibRaw and exiv2. These are stock Slackware packages and the two are being upgraded ahead of Slackware, so that the Plasma5 packages can pick them up. Pat added the shared libs for the older releases to ‘aaa_elflibs’ so that none of the Slackware packages will break when you install this month’s Plasma5 packages.
And I have removed qt5-speech because I overlooked that this is already part of the big qt5 package.

I rebuilt kdelibs in the KDE4 section, just like Pat did for Slackware. This removes hardcoded TLSv1 allowing TLSv1.1 and TLSv1.2.

Frameworks 5.64.0 is an incremental stability release, see:

Plasma 5.17.2 is a an incremental bug-fix release in the 5.17 cycle of the KDE desktop environment. See

In plasma-extra I updated latte-dock.

Applications 19.08.3 is a stability and bugfix update for the 19.08 cycle, see

In applications-extra I updated digikam, kile (finally 3.0 beta 3!), kstars and kdevelop-pg-qt, kdevelop, kdev-php, kdev-python. Due to the new exiv2 and LibRaw I rebuilt krename and krita.

KDE Telepathy is no longer part of my ‘ktown’ distribution of KDE Plasma5.

Where to get it

Download the KDE-5_19.11 from the usual location at . Check out the README file in the root of the repository for detailed installation or upgrade instructions.

Development of Plasma5 is tracked in git: .
A new Plasma5 Live ISO will arrive later this week (hopefully… I have some stuff high on my TODO list) and you will find it at (rsync://

Have fun! Eric

New LibreOffice packages for Slackware 14.2 and -current

I uploaded the latest releases of LibreOffice for Slackware 14.2 and -current.

On Slackware 14.2 you can enjoy the stable 6.2.8 version, this is the last release in the 6.2 series. For Slackware-current I went with the latest and greatest ‘fresh’ release of 6.3.3 which became available last week.

Note that the packages for LibreOffice in my repository, do contain “libreoffice-kde-integration” for Slackware -current, containing Qt5 and KDE5 (aka Plasma5) support. On the other hand, packages for Slackware 14.2 do not contain “libreoffice-kde-integration” any longer.
If you run Slackware-current but do not have KDE5 packages installed at all, don’t worry. LibreOffice will work great – the KDE integration package just will not add anything useful for you. On the other hand, if you have Plasma5 installed you will benefit from native file selection dialog windows and other integration features. And even if you do not have Plasma5 but you do have Qt5 installed, then you will be able to run LibreOffice with Qt5 User Interface elements instead of defaulting to GTK3.

If you want to compile Libreoffice 6.3.2 packages yourself using my SlackBuild, then be aware that by default the KDE5 support is disabled. You will have to set the value of the script parameter “ADD_KDE5” to “YES”. Additionally you will have to install the packages that this functionality depends on otherwise the compilation will fail.
Read the ‘README.kde5‘ file in the source directory for the list of packages you’ll need. All of them can be  found in my ‘ktown’ repository:

Enjoy! Eric
