Unfortunately there is no way to disable this feature for individual packages. It will work for script addons, but Qalculate! needs to compile native libraries, which is not supported. Sorry for the trouble. Which distribution are you using? - Oct 21 2019

Sorry, I have never heard of ocs before. Looks like this is currently not supported. A list of supported ways to install is listed here: https://github.com/dschopf/plasma-applet-qalculate/blob/master/README.md - Oct 18 2019

I added support for launching an application from the logo in the github repo: https://github.com/dschopf/qalculate
Can you check if this meets your requirements? - Apr 04 2019

I'm not sure I fully understand your request. Do you want a button on your task bar which launches the app or do you want a button (or any other clickable object) inside the widget? - Apr 03 2019

It's difficult to guess what the problem might be. Are there any errors when installing the plugin?
Maybe you could open an issue on Github with some more details like which distribution, compiler and KDE version you are using. - Jun 07 2018

That part about the requirement of libqalculate v2.5 only refers to the new feature of using the two's complement representation for negative numbers. Apart from that the latest version should hopefully work with all (recent) versions of libqalculate (including v2.2).

The error message you receive looks like an ABI incompatibility between libqalculate and the plugin.
If possible please open a bug report on the Github page, which is much better suited to discuss such issues. - May 30 2018

This looks like a version conflict. When you use libqalculate 2.0.0 it should not try to link stopPrintControl().
How did you install the libqalculate? Manually or with a package manager? What does the output of the cmake command say.
It should say something like this:
-- Checking for module 'libqalculate>=0.9.8'
-- Found libqalculate, version 2.4.0 - Apr 25 2018

I uploaded a new experimental version to github which should support libqalculate v2.0.0 much better.

Are you sure this issue is related to the plasmoid? I have upgraded two different machines to libqalculate 2.0 and both are working fine.

You can use "plasmoidviewer --applet org.kde.plasma.qalculate" to run it separately from KDE and see some debug messages in the konsole. - Sep 08 2017

This issue has been fixed in v0.2.1. - May 09 2017

Using an input box as a widget seems to be rather difficult and not
properly supported by KDE. I will look into making the icon
configurable. - Oct 17 2016

You probably are missing the Extra CMake Modules (ECM) package.
Just search your package manager for "ecm" or "extra cmake modules" and the
installation should be pretty easy and straightforward.

I just added install instuctions to the description. If that doesn't work for you please let me know. - Oct 01 2016
