Hi, I just installed the jupyter-c-kernel on my jupyterhub server (i installed it with sudo to have the kernel available for all the users). When I try to execute the simple hello world example i got this log in the notebook shell output:

[I 2016-06-07 04:51:13.171 epinux kernelmanager:89] Kernel started: 22a3c6c7-8932-4cf2-b377-b4f33f571430

I guess is an issue on how I installed the kernel, thanks for looking into this.

It seems the error was generated by a missed resource directory. Ii copied it from the src root into:

/usr/local/lib/python3.5/dist-packages/jupyter_c_kernel-1.0.0-py3.5.egg/

And now hello world works fine! 😃 I’ll test with more complex c code and I’ll report here if any problem. Thanks!

Hello, Could you please help me with the installation on Ubuntu 17.04? I followed the instructions:

pip install jupyter-c-kernel
install_c_kernel

install_c_kernel returned an error, permission denied.

So I tried with install_c_kernel --user and it worked out fine.

Nevertheless, if I run the notebook with the hello world example ( or any code), the kernel does not return any output, it just runs but it does not return anything. It does however, send error messages if the code is wrong.

Thanks,
