Arch Linux User Repository

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.

Indeed, I can confirm the issue report by @Ayaka, and resolve it with @kaelingre's suggestion below.

@Ayaka: I had a similar problem. It is because (intermediate) build files of cling are needed, which are often deleted once the package has been built (e.g. when using yay). A workaround is to rebuild cling and make sure the folder '/build/cling/src/build', in your case, is not deleted. (E.g. run 'makepkg' in '/build/cling')

make[2]: *** No rule to make target '/build/cling/src/build/lib/libclingInterpreter.a', needed by 'libxeus-cling.so.0.13.0'.  Stop.
make[1]: *** [CMakeFiles/Makefile2:88: CMakeFiles/xeus-cling.dir/all] Error 2
