Is this because the package is outdated?

error: use of deleted function

Hi there, anybody knows if this issue is closed in conda packages but open in AUR?

Thanks in advance.

Edited: I can confirm, this behaviour is not present in https://mybinder.org/v2/gh/jupyter-xeus/xeus-cling/stable?filepath=notebooks/xcpp.ipynb, but yes in xeus-cling from AUR.

jupyter-widgetsnbextension is not available anymore. Shouldn't the dependency be satisfied with ipywidgets though?

Very many thanks @kaelingre. The package is now up to date.

I managed to build 0.15.0. PKGBUILD:

Hi, now jupyter is replaced by jupyter-notebook.
