Cling Kernel for Jupyter on Ubuntu

I built Cling on my laptop with Ubuntu 15.04 following the instructions given on https://github.com/root-mirror/cling#jupyter because I wanted to use the Cling kernel for Jupyter. I installed Jupyter, I checked that Cling is in my PATH, but when I type the command

jupyter kernelspec install cling

I get the following

OSError: [Errno 2] No such file or directory: 'cling'

Someone knows what's happening?

Solution

  • According to the source code, jupyter kernelspec install command expects the path to the directory containing kernel spec file (kernel.json) as an argument. So if you cloned the cling repository in, say, ~/cling/src, this should work:

    jupyter kernelspec install ~/cling/src/tools/cling/tools/Jupyter/kernel/cling
