InstallationAndUsage

You will first need to install dependencies.

mamba install cmake cxx-compiler nlohmann_json cppzmq xtl jupyterlab
clangdev=14 cxxopts pugixml -c conda-forge

Note: Use a mamba environment with python version >= 3.11 for fetching clang-versions.

The safest usage is to create an environment named xeus-clang-repl.

mamba create -n  xeus-clang-repl
source activate  xeus-clang-repl

Installing from conda-forge: Then you can install in this environment xeus-clang-repl and its dependencies.

mamba install xeus-clang-repl notebook -c conda-forge
