How to use QT subsystem on Kubuntu 16.04 (Xenail)?

Kukulkan · **Posted:** Thu Jun 25, 2020 4:10 pm

Hi,

I tried to use QT subsystem with PB 5.71 on my Kubuntu 16.04 machine. This is needed because I'm not able to use the WebGadget on Ubuntu systems from 19.04 or newer. There is no libwebkitgtk-3.0-0 available any more, but PB needs this as hard dependency. So I thought I try it with QT as a workaround, as Fred seem to not care about the problem since more than a year...

Sadly, the checkinstall.sh script does not support QT and if I try with the help of freak (link), I get this (German system):

Code:

$ sudo apt-get install qtbase5-dev qttools5-dev qtmultimedia5-dev qtdeclarative5-dev libqt5svg5-dev libqt5webkit5-dev libqt5multimedia5-plugins

Any idea how I can use the QT subsystem? There seem to be a lot of dependency issues and version incompatibilities...

Did you give the linux install a try? It supports GTK and QT.

Hi,

the page is having SSL Certificate issues. Not that trustworthy. And behind, there is a tool to make executable setups. But I like to compile using PB with QT, and this does not work because of missing dependencies. And trying to install them results in the errors from first post. How is this to get fixed by that installer-tool? Maybe I did not understand?

Ubuntu 16.04 is out of LTS. Is better to update Ubuntu 18.04 LTS.
No problem with QT

That's not correct. The general support of Ubuntu 16.04 LTS ends in 2021-04, the security support in 2024-04. You may take a look into this release table in Wikipedia.

I have been asking for a long time for an up-to-date checkinstall and an official statement about which Linux distributions (including their versions) are supported.
But I have never received an answer.

I understand that Fred and the company's resources are limited.
That is why I am waiting for an honest specific list.

My hoster made same mistake during the last upgrade. Dunno when that will be fixed.

The tool knows the necessary GTK and QT Libraries and recognizes the environment it runs on. It shows the detected environment (so the user can verify it and abort it if something seems wrong).

Then it looks for matching setup files of the selected UI's you want to use and if it knows the required libraries for the current environment it runs in. Then you can simply let the tool install all required libraries with a click. The tool supports 32-bit and 64-bit linux installations and if things go as expected, any Linux preparation for different UI developments is a 2 or 3 mouseclick effort. But i can relate that you would not download and run a "unknown" binary from an "unsafe" website due to the SSL problem currently.

The full source is in the archive though and the environment detection and matching basically points to a ascii textfile which includes the list of required libraries. So you could download it but instead of installing and running, decompress it and manually use the text files from the architecture folder to do the same

Btw. the next big trust problem would have been the fact that the installation of libraries would really require root rights to start the package manager

To deal with all these trust problems, i simply develop inside linux virtual machines.

Thats exactly the reason why i started the linux installer project and the necessary tool. Fred gave us the tools we need to do this ourselves.
