9 Best plasma addon!
Most difficult addon to install (after 50 KDE OS barebone installs of 10 different distros). Use PPA or AUR if you're lucky.

That is unfortunately true. But due to the fact that it needs to interface with the qalculate library on the system there is currently no other way to make it work.

Hi.
I've installed with ocs but I can't see the applet if I try to add it to the panel. I've selected add graphic element to panel but QCalculate not seems available. How I can add to panel (Task manager or whatever named is)? Thanks

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

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?

hi,
can you put a link in the ui to get quickly acces to the GTK-UI. ?
e.g. clik on the picture logo will launch the app!

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?

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?

The plasmoid doesn't give me results, only "Error" as result. I don't have errors in the compilation and qalculate-gtk works fine. I search it, but I can't find anything. Could you give any tip?

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.

Nevermind. My fault. Forgot to read the bit where you said that libqalculate 2.5 or higher is required. Thanks!!

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.

Similar error when try with v0.4.0 libqalculate-2.4.0


Could you give any tip or so?

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
