OpenBSD KDE Status Report

23 Jan 2021

OpenBSD has managed to drop KDE3 and KDE4 in the 6.8 -> 6.9 release cycle. That makes me very happy because it was a big piece of work and long discussions. This of course brings questions: Kde Plasma 5 package missing.

After half a year of work, I managed to successfully update the Qt5 stack to the last LTS version 5.15.2. On the whole, the most work was updating QtWebengine. What a monster. With my CPU power at home, I can build it 1-2 times a day which makes tasting a little bit annoying and time intensive.

But today we can be happy about an up-to-date KDE stack in OpenBSD. Currently - at the end of January - our stack is very up-to-date:

  • Qt 5.15.2
  • Qt Creator 4.14.0
  • KDE Frameworks 5.78.0
  • KDE Applications 20.12.1 (Almost everything!)
  • Kdevelop 5.6.1
  • Kirta 4.4.2
  • KMyMoney 5.1.1
  • DigiKam 7.1.0

I try to keep KDE Applications 20.12.x stable until the 6.9 release.

Let’s move on to the topic of KDE Plasma. The Plasma desktop and some other KDE applications have a strong dependence on the Wayland. As long as there is no Wayland under OpenBSD, there will also be no KDE Plasma.

It can be observed that more and more KDE applications already prefer a strong dependency on Wayland. For example Spectacle.

In summery, no OpenBSD Wayland support no KDE Plasma and probably less and less KDE applications.

Workstation setup

23 Dec 2020

In the days when almost everyone works from home, it seems a good time to write about my workstation setup at home. I built my dream setup some months ago, before COVID19, and finished it at the beginning of the year. My first tweet followed in February:

Timing is everything.

Here is a list of my requirements for a modern setup/desk:

  • Height adjustable
  • Solid wood plate
  • No cable spaghetti
  • Few to no visible cables
  • Suitable for a minimum of 3 devices:
    • OpenBSD workstation
    • OpenBSD/Linux ThinkPad with docking station
    • MacBook Pro from my company
  • Easy to switch among devices
    • Use one main keyboard and mouse for all devices
  • It should look good.

Standing Desk

I think IKEA has the best value for money. The table is very solid and high quality. I have installed a socket and a cable bushing on the left and right side. It’s really easy to drill through the desk. On the left side I have the socket with USB connection, and on the right side are cables for charging daily devices.

Switching among devices

I solved the switching problem a long time ago. For this I use:

Originally, I had it on the table under my monitor. During my big reconstruction, I put it under the table. I just put some glue on it and, to my surprise, it worked very well. I used the following product:

Pattex Montagekleber Kleben statt Bohren Wasserresistent

Cable spaghetti challenge

To solve the cable spaghetti problem I bought the following products from ebay(.de) and Amazon(.de) and installed them:

Keyboard

In early 2018 I decided to buy an ergonomic keyboard. It was a hard decision, but in the end I decided to buy ErgoDox EZ. The keyboard is really expensive. Okay, that I knew, but what really annoyed me were the stress at customs and the handling charges. I paid about 60 Euro in customs duty in addition to the purchase price. If you want to be an ErgoDox EZ EU consumer, you have to dig deeply into your pockets. Anyway, I do not regret my decision! I can write very well and quickly with ErgoDox, but I lose the ability to write with a normal keyboard. This is not a problem in the times of COVID19 and the home office, but when I am on-site at a customer it is often annoying to work without the ErgoDox EZ.

k2k20 - OpenBSD Hustenthon Burg Liebenzell

21 Sep 2020

First of all let’s talk about the word Hustenthon. Husten is the German word for cough(ing). A small allusion to the current COVID19 situation. (This article does not intend to make an assessment of or talk about COVID19).

Due to the pandemic, this hackathon seemed to be called very spontaneously. Fortunately, the hackathon was over a weekend. This enabled me to attend without missing any professional obligations. On Friday morning, shortly after sunrise, I took the train to Bad Liebenzell. On the train I worked for my employer until I reached Karlsruhe at about 11am. I swapped my MacBook for my OpenBSD ThinkPad T470s.

Only a few days before the hackathon I had committed the big KDE frameworks 5.73.0 and KDE applications 20.08.0 update. With perfect timing, of course, because 1-2 days later 20.08.1 was released. So I had enough time the week before the hackathon to prepare a update diff.

I spent the time in the Bummelbahn (a small and slow train) from Karlsruhe to Bad Liebenzell reviewing my 20.08.1 update diff again. Arrived in the hackroom and connected via em0, my first action was to commit the update. I had a rough plan of what I wanted to do during the weekend: Focus on KDE bugs. Push more OpenBSD-related KDE patches upstream. This worked well in the weeks before the hackathon and you can see first bits landed in KDE Frameworks 5.74.0.

On ports@ I found security/qtpass which interested me as I always try to have a look at new Qt applications to import. Next was sysutils/htop and then security/qca-qt5. Then I got the stupid idea to commit my games/nethack Qt3 removal which ended up with a lot of noise and two additional commits. If there is one thing I have learned over the years, it is that strong nerves are needed to touch old ports-stuff. It is very difficult to work on such large submodules without stepping on someone’s feet from time to time.

Speaking of large submodules, Qt released Qt 5.15.1, the first patch release of Qt 5.15 LTS.

On Saturday, during my morning run, I decided to start working on a Qt 5.15.x update for the next release. Once again, a lot had happened at Qt between our version, 5.13, and the LTS 5.15.1 version. The update has gone well so far. I was able to update all submodules and the first tests were successful. I have tried to update Qt without updating x11/qt5/qtwebengine but it seems to be even more work because you have to fix so many qt-related parts in qtwebengine. I am working on a complete update including x11/qt5/qtwebengine. I’m optimistic.

My logs often contain desktoptojson: vfprintf %s NULL in "Warning: %s(%s:%u, %s) and I found out that this comes from KDE. More precisely, from devel/kf5/kcoreaddons. Quickly found the issue, fixed, sent upstream, merged upstream and committed in CVS.

Based on a very productive devel/kf5/kjs pull request review from upstream, I was able to fix the thread stack base detection in devel/kf5/kjs. The old patch points to the top and not to the base (end) of the thread stack.

I spent some time looking into devel/cmake. There is a sometimes bug in CMake on OpenBSD. This has often been spotted by naddy@. “A shared library has been built with the version number from SHARED_LIBS, but during the fake stage this is forgotten and the upstream version number used instead. This produces an error, because the file doesn’t exist." – (read more)[https://marc.info/?l=openbsd-ports&m=159733025922436&w=2]

I don’t think I have found this bug but maybe I have. There is a mistake in the cmGeneratorTarget_cxx patch. This creates a wrong scope. this->IsFrameworkOnApple() is present twice and the first one adds a wrong bracket which creates a scope to the end of the whole function. Maybe this triggers our random issues with cmake. We’ll see. More bulk builds will show.

During the Qt 5.15 update I noticed that x11/qt5/qtspeech does not build at all. I looked at our version in CVS and found that it is also broken or useless because it has no backend. A fix was quickly found and I was able to show bluhm@ a voice message via x11/kde-applications/kmouth in the hackroom. Now text-to-speech should again work for all consumers.

All in all I can look back on a really successful hackathon. Since I mainly operate only in ports, it was nice to meet people from the kernel space. On Monday morning I left the castle in the direction of Nürnberg where I worked for a customer for the next two days.

Thank you very much to Genua, the team from Burg Liebenzell and jan@ for organizing a great hackathon. Thanks pamela@ for the English proof-reading!

OpenBSD KDE status

20 May 2020

This short blog post should summarize the KDE/Qt work done in OpenBSD 6.7 and my plans for 6.8.

6.7

The most important achievement was the Qt5 update from 5.9 to 5.13.2. Furthermore, I am very happy that many KDE Applications have made it into the new release. Currently we count 143 KDE5 applications and all KDE Frameworks addon libraries (except Wayland).

The KDE applications are available in version 19.12 and the framework in 5.68.0. In addition, there are some heavyweights in the ports tree:

… and many more exciting KDE/Qt applications.

After the ports-lock

Shortly after the release I committed and announced that I had managed to port the QtWebEngine. All parts are now in the tree and wait until they are unleashed.

It will allow us to port many new applications and give us the opportunity to update a few things. espie@ and tracey@ unbreak kdenlive, which means we have finally a video editor back in OpenBSD.

Next?

As an independent person it is always difficult to plan in the open source environment . Let’s say it like this, I have the following goals for 6.8:

  • Finally enable qtwebengine (easy).
  • Porting the remaining KDE Applications (x11/kde-applications). This is mostly the PIM stuff: Kontact, KMail, KAddressBook KOrganizer https://kontact.kde.org.
  • Get rid of KDE4 (x11/kde4). The conflicts are annoying and nobody uses this stuff anymore. Prove me wrong!

As you can imagine, working on such a large number of ports is very time consuming. I am happy about any feedback and of course about any kind of support.


How to build Qt5 applications with CMake on OpenBSD

29 Mar 2020

If you want to develop a Qt application like me on OpenBSD, you may face the same issue. CMake can’t find the Qt modules.

$ cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug ~/src/happy-qt-hacking

CMake Error at CMakeLists.txt:18 (find_package):
  By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5" with any of
  the following names:

    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!
See also "/home/rsadowski/build-happy-qt-hacking/CMakeFiles/CMakeOutput.log".

This is simply because OpenBSD does not install the Qt5-CMake modules in /usr/local/lib/cmake/ but in /usr/local/lib/qt5/cmake.

In order for find_package to be successful, Qt 5 must be found below the CMAKE_PREFIX_PATH, or the Qt5_DIR must be set in the CMake cache to the location of the Qt5Config.cmake file.

Qt CMake manual

The easiest way to use fix the issue is to set Qt5_DIR

Qt5_DIR=/usr/local/lib/qt5/cmake cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug ~/src/happy-qt-hacking
