To install and configure Xeus (the native C++ implementation of the Jupyter kernel protocol) alongside its messaging and networking layer (xeus-zmq) on Linux, you can either utilize pre-compiled packages or build it directly from source.
Note: If you are looking for an instant-messaging application like Facebook Messenger or GNUnet Messenger on Linux, third-party wrappers such as Caprine via Snap/Flatpak or GNUnet Messenger via Flathub are typically used. The guide below outlines the deployment of Jupyter Xeus / xeus-zmq, which acts as the messaging engine backend for Jupyter kernels. Method 1: Quick Installation via Mamba / Conda
The easiest and recommended way to install Xeus on Linux is by using the conda-forge channel via the Mamba or Conda package managers.
# 1. Add the conda-forge channel and set strict priority conda config –add channels conda-forge conda config –set channel_priority strict # 2. Install xeus and its zeroMQ backend using mamba (or conda) mamba install xeus xeus-zmq -c conda-forge Use code with caution. Method 2: Building from Source
If you require custom configurations or lack a Conda environment, you can build the binaries directly. 1. Install System and Library Dependencies
On Linux systems, Xeus requires a C++14 compliant compiler, CMake, and system-level UUID libraries. For Ubuntu/Debian-based distributions:
sudo apt-get update sudo apt-get install build-essential cmake uuid-dev libssl-dev Use code with caution.
If you prefer installing the development headers inside a package environment, you can fetch them via mamba:
mamba install cmake zeromq cppzmq OpenSSL xtl nlohmann_json libuuid -c conda-forge Use code with caution. 2. Build and Install Core Xeus
Clone the primary repository from the Jupyter Xeus GitHub organization, then compile and install it globally:
git clone https://github.com cd xeus cmake -D CMAKE_BUILD_TYPE=Release . make sudo make install cd .. Use code with caution. 3. Build and Install the ZeroMQ Messaging Engine (xeus-zmq)
To enable communication with the Jupyter middleware protocol, you must build the ZeroMQ transport layer companion plugin:
git clone https://github.com cd xeus-zmq cmake -D CMAKE_BUILD_TYPE=Release . make sudo make install Use code with caution. Configuration and Kernel Deployment
Xeus is a library foundational middleware rather than a standalone standalone user application; it is configured by launching a specific language kernel wrapper constructed over it (such as xeus-cling for C++ or xeus-python).
To verify that your installation communicates properly with a front-end interface, register or run a compliant kernel context: Install a specialized Xeus Kernel: mamba install xeus-python notebook -c conda-forge Use code with caution. Launch the Interface: jupyter notebook Use code with caution.
Verify the Engine: Open a notebook page and switch your kernel selection to XPython to route your inputs natively through the Xeus engine stack. If you’d like to tailor this setup, please share:
Your specific Linux distribution (e.g., Ubuntu, Arch, Fedora)
The programming language kernel you plan to run over Xeus (e.g., C++, Python, SQL)
