Build Failure on Modern Linux with Conda

[mamiri2025]

Hello,

I am trying to use the aviso-lagrangian library and have been unable to install it on a modern Ubuntu server (using both venv and conda). After extensive troubleshooting, we've found several issues that prevent it from being installed.

Summary of Issues Encountered:

1. Building from Source Fails: The build scripts are incompatible with modern tools.

   • The CMakeLists.txt files (both in the root directory and in third_party/pybind11) require an old version of CMake and must be manually patched.
   • The setup.py script has faulty logic for detecting libraries (Boost, UDUNITS2, NetCDF) inside a Conda environment and must also be manually patched.
   • Even after patching all of the above, a clean build using a Python 3.9 Conda environment produces a library that fails on import with: ImportError: dynamic module does not define module export function (PyInit_core).

2. Pre-compiled Conda Package Fails: The package on the fbriol Conda channel requires Python 3.7. However, when trying to create an environment with it, it has an unsolvable dependency conflict with new packages (like conda-anaconda-tos and menuinst) that are included in modern Conda distributions.

It seems the library is not installable on a modern Linux system using any standard method. Could you please provide guidance or an updated Conda package?

Thank you for your work on this project.
