My thoughts on Slackware, life and everything

February release of the Plasma5 Desktop for Slackware

Yesterday, I uploaded my Febrary’18 release of Plasma 5 packages for Slackware-current. The KDE-5_18.02 release contains: KDE Frameworks 5.43.0, Plasma 5.12.0 and Applications 17.12.2. All based on Qt 5.9.4 and exclusive for Slackwarecurrent because as explained in a previous post, I stopped providing regular Plasma 5 version updates for Slackware 14.2 (only security updates).
There’s again a choice of ‘latest‘ and ‘testing‘ where the ‘testing’ repository contains 17 recompiled packages that provide a Wayland compositor stack. This means you can have a working Plasma5 Wayland session if you use ‘testing‘ as opposed to ‘latest‘.
The ‘testing‘ repository is for… testing. Do not use those packages on a production environment unless you are familiar with Slackware, debugging graphical sessions and know your way around slackpkg/slackpkg+.

What’s new in this KDE 5_18.02 release

  • The ‘deps’ section has been graced with an updated qt5 package. I opted for qt5-5.9.4 which is the last one in the 5.9 series in the hope that Pat updates to qt5-5.10 when adding Plasma5 to Slackware.
    Also, I added two new packages here: cryptopp and cryfs. The Plasma Vault requires an encryption backend but I had not yet added one so the application was not useful. Cryfs seems to be the best choice (alternative backends would be encfs or tomb). I had ignored Vault for the past few releases but it looks like an interesting solution to store your data securely on cloud storage so I decided to make it functional.
  • Frameworks update is a stability release, see: https://www.kde.org/announcements/kde-frameworks-5.43.0.php .
  • Plasma is the highlight of the month. Version 5.12 is a Long Term Support (LTS) release, which replaces the previous LTS version 5.8. See https://www.kde.org/announcements/plasma-5.12.0.php .
  • Applications 17.12.2 is an incremental update for the 17.12 series and fixes some bugs.
    See https://www.kde.org/announcements/announce-applications-17.12.2.php .
  • In ‘applications-extra’ I have upgraded the packages for calligra and added calligraplan.

The accompanying README file contains full installation & upgrade instructions. I have some further reading material in case you are interested in the Wayland functionality of the ‘testing’ repository: README.testing.

If you are interested in the development of KDE 5 for Slackware, you can peek at my git repository too.

A new Plasma5 Live ISO image (based on liveslak-1.1.9.6) will be uploaded soon to http://slackware.nl/slackware-live/latest/ , in case you want to try the new Plasma5 desktop out first in a non-destructive way.

Have fun! Eric

Finally: VLC 3

largeVLCIt took the VideoLAN developers several years of development to leave the ageing v2 releases of their VLC player behind and release a shiny new version ‘3’. This is also the first version which unifies the releases for all platforms the player can run on.
Lots of changes went under the hood and I encourage you to read the release notes. The new release contains working ChromeCast support using a software stack the developers wrote from scratch, where the video’s you cast are transcoded on the fly if necessary. The UPnP support which was broken for many years, has been re-written and finally works again, so that you can watch the movies you make available on your LAN using for instance Plex or Universal Media Server.

When I compile the VLC package I try to follow the VideoLAN guidelines for its supporting libraries, so that the user experience and functionality matches that of the official binaries as closely as possible. That resulted in several changes to the libraries used by VLC:

  • Updated internal libraries: libass, libdvdcss, libdvdnav, libdvdread, libbluray, ffmpeg, live555, libssh2, x262, x264.
  • New internal libraries: microdns, sdm, srt.
  • Removed libraries (no longer used internally): aacenc, daap, faad, faac, vcdimager.

A note about dependencies for the new package:
My Slackware packages for VLC are mostly self-contained with all of the supporting libraries compiled into the package. This makes for a minimal dependency on external libraries/packages. But there are some caveats with the new release: most importantly, its interface has switched from Qt4 to Qt5. While Slackware contains a ‘qt4’ package, it does not contain ‘qt5’ and therefore, the vlc-3.0.0 package introduces three new dependencies, all related to the Qt5 GUI: libxkbcommon, qt5 and qt5-webkit. On Slackware 14.2, two more packages are needed which are already incorporated into slackware-current: libinput and libwacom (the latter one only for 64bit).

A warning to users who built a ‘qt5’ package themselves, using the SlackBuild script at slackbuilds.org:
Un-install that ‘qt5’ package please and install mine. The ‘qt5’ package built with the SBo script will make VLC crash with a segmentation fault.

A note on compiling:
When you want to compile VLC 3 yourself, be sure to install java8 and apache-ant or your build will fail.

Where to find the new VLC packages:

Rsync access is offered by the mirror server: rsync://slackware.nl/mirrors/people/alien/restricted_slackbuilds/vlc/ .

For BluRay support, read a previous article for hints about the aacs keys that you’ll need.

Note that I only built packages for Slackware 14.2 & -current. I stopped creating packages for Slackware 14.1 and earlier because of the effort it takes to build 4 packages for every Slackware release.

My usual warning about patents: versions that can not only DEcode but also ENcode AAC audio can be found in my alternative repository where I keep the packages containing code that might violate stupid US software patents.
