xeus-cling is a Jupyter kernel for C++ based on the C++ interpreter cling and
the native implementation of the Jupyter protocol xeus.
xeus-cling has been packaged for the conda package manager on the Linux and OS X platforms. At the moment, we are not providing packages for the Windows platform.
To ensure that the installation works, it is preferable to install xeus-cling in a fresh conda environment. It is also needed to use a miniconda installation because with the full anaconda you may have a conflict with the ZeroMQ library which is already installed in the anaconda distribution.
The safest usage is to create an environment named cling with your miniconda installation:
conda create -n cling
conda activate cling # Or `source activate cling` for conda < 4.6
Then you can install in this environment xeus-cling and its dependencies
conda install xeus-cling -c conda-forge
You will first need to create a new environment and install the dependencies:
conda create -n xeus-cling -c conda-forge cmake xeus=0.25.0 cling=0.7.0 clangdev=5.0 llvmdev=5 nlohmann_json cppzmq xtl pugixml cxxopts
conda activate xeus-clingYou can then compile the sources:
cmake -D CMAKE_INSTALL_PREFIX=${CONDA_PREFIX} -D CMAKE_C_COMPILER=$CC -D CMAKE_CXX_COMPILER=$CXX -D CMAKE_INSTALL_LIBDIR=${CONDA_PREFIX}/lib -D DOWNLOAD_GTEST=ON
make && make installIf you don't have a frontend already installed (classic Jupyter Notebook or JupyterLab for instance), install one:
conda install notebook -c conda-forgeTo try out xeus-cling interactively in your web browser, just click on the binder link:
To get started with using xeus-cling, check out the full documentation
http://xeus-cling.readthedocs.io/
Launch the jupyter notebook with jupyter notebook and launch a new C++ notebook by selecting the C++14 kernel in the new dropdown.
You can now make use of the C++ programming language in the Jupyter notebook.
Quick help is shown on the pager with the special ? magic.
Content for the quick help is available for the standard library, and can be made available for third-party packages.
A C++ backend for the Jupyter interactive widgets is available in the xwidgets package.

xeus-cling requires its dependencies to be built with the same compiler and same C runtime as the one used to build cling.
