Usually whenever libqalculate was upgraded, all that I had to do is to recompile the plasmoid. However, after I upgraded libqalculate to 2.0 and recompiling the plasmoid, I was unable to start plasmashell; there was a "malloc(): memory corruption" message even. I was able to get plasmashell starting again after removing the plasmoid.

The moral of the story is, that plasmoid 0.3x and libqalculate 2.0 do not seem to like each other.

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.

Can you please add a pre-compiled version, so it can be installed via GHNS?
I really missed this applet from KDE4

When I try using "cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -DKDE_INSTALL_LIBDIR=lib -DKDE_INSTALL_USE_QT_SYS_PATHS=ON"
I got an error

"CMake Error at CMakeLists.txt:10 (find_package):
Could not find a package configuration file provided by "ECM" with any of
the following names:

ECMConfig.cmake
ecm-config.cmake

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

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.

Thank you! Worked very well. I use it on the panel so I would suggest the following: a) change the icon (it's a sore bleed among the Plasma/Breeze minimalism) or either replace the panel version of the widget with a small input box to directly input expressions. Thanks!!

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.
