zainul1114 commented 4 years ago

Hi, I am trying setup C++ kernel, and i downloaded file from below link and Python3.6 is default https://root.cern.ch/download/cling/cling_2020-08-25_ROOT-centos7.tar.bz2 i have installed and added kernel to jupyterhub, but C++ kernel is dying every time. cp cling_2020-08-25_ROOT-centos7/* /share/apps/platform/ai/cling

my .bashrc file export PATH=/share/apps/platform/ai/cling/bin:/share/apps/platform/ai/cling/include:$PATH export LD_LIBRARY_PATH=/share/apps/platform/ai/cling/lib:$LD_LIBRARY_PATH

cd /share/apps/platform/ai/cling/ pip install -e . jupyter-kernelspec install cling-cpp14

cat /usr/local/share/jupyter/kernels/cling-cpp14/kernel.json { "display_name": "C++14", "argv": [ "jupyter-cling-kernel", "-f", "{connection_file}", "--std=c++14" ], "language": "C++" }

[root@master ~]# jupyter-kernelspec list Available kernels: python3 /share/apps/platform/ai/py36/3_6_9/share/jupyter/kernels/python3 cling-cpp14 /usr/local/share/jupyter/kernels/cling-cpp14

I am getting below error image and my logs are
