The fetched libcurl 8.22 refuses to compile against OpenSSL 1.1 ("OpenSSL 3.0.0
or greater required"), so a viewer build on an older distro fails deep inside a
dependency with nothing in the requirements list to explain it.

Software requirements
Operating system
Recommended operating system is Red Hat Enterprise Linux (RHEL) / Rocky Linux versions 8 or 9. For this operating systems we provide RPMs with pre-built binaries to simplify deployment. On experimental basis we also build repositories for Ubuntu 22.04 and 24.04.
Running Jungfraujoch on Red Hat Enterprise Linux 7 is currently not tested and not recommended, but likely possible with providing some packages from external repositories.
Two programs additionally run on Windows 11: the desktop viewer jfjoch_viewer, shipped as a
pre-built installer, and rugnux, the offline analysis CLI, shipped as a .zip. Both
can be built from source with Visual Studio 2026 (MSVC) and CUDA 13.3 — the viewer additionally
needs Qt 6.11; see
jfjoch_viewer ▸ Building from source on Windows.
The Windows artefacts bundle the Qt runtime (viewer only) and, on the CUDA builds, the cuFFT DLL, so
end users need neither Qt nor a CUDA toolkit installed — only an NVIDIA GPU driver for the GPU path.
On Linux the portable archives link CUDA entirely statically and so need nothing but the driver.
rugnux is also built for 64-bit Arm Linux (GH200, DGX Spark). The rest of Jungfraujoch is
Linux-only and x86-64-only. See Release contents for the CPU baseline and
CUDA requirements of each released package.
Software dependencies
Required:
- C++20 compiler and C++20 standard library; recommended GCC 11+ or clang 14+ (Intel OneAPI, AMD AOCC)
- CMake version 3.26 or newer + a build tool (GNU make or Ninja)
- zlib compression library
- Eigen (header-only linear algebra library), version 3.4.x (the build requests
Eigen3 3.4, which Eigen's same-major-version rule does not satisfy with 5.x)
HDF5, libtiff and libjpeg-turbo used to be required system packages; they are now downloaded and built automatically by CMake (see the note below), so they no longer need to be installed.
Optional:
- CUDA compiler version 12.8 or newer - required for the MX fast feedback indexer and GPU analysis
- FFTW library - for indexing if GPU/CUDA is absent (also auto-downloaded by CMake)
- Node.js - to build the frontend
- Qt version 6 (for jfjoch_viewer)
- OpenSSL 3.0 or newer and the Kerberos development headers (
krb5-devel/libkrb5-dev) - required to build jfjoch_viewer on Linux, where the fetched libcurl uses them for TLS and Negotiate; a build on OpenSSL 1.1 fails in libcurl
Many further dependencies (spdlog, Zstandard, HDF5, slsDetectorPackage, libzmq, libtiff,
libjpeg-turbo, Ceres, the fast feedback indexer, Catch2, ...) are downloaded automatically
by CMake and statically linked; building therefore requires network access on the first configure.
zlib and Eigen are the exception — they must be preinstalled (found via find_package); on Windows,
where they are not present system-wide, install them into a prefix and point CMAKE_PREFIX_PATH at
it (see Building from source on Windows).
Others are vendored directly in the source tree. The complete list of third-party components, with
