Hello!
Disclaimer: I know that Salome-meca does everything I need but I didn’t find a way yet to open salome with singularity on NixOS (app don’t open and terminal exit). And btw if someone knows how to build it from source…
So basically here is my issue:
I’m trying to use paraview 6.0.0 on my NixOS machine, which is available in the unstable channel of nixpks, because I want to visualize code-aster results file. Unfortunatly I can’t see the MEDReader plugin in the plugin manager.
Nixpkg provide paraview by building it from source ( see [nixpkgs/pkgs/by-name/pa/paraview/package.nix at nixos-unstable · NixOS/nixpkgs · GitHub](https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/by-name/pa/paraview/package.nix#L109) ), maybe the issue is from here?
Thanks for your help!

The MEDReader is an external plugin that is not part of ParaView source code but is from the Salome project.
It is packaged in our binary release thanks to our superbuild (basically a package manager) but the logic would have to be replicated by NixOS to be able to offer it in their build.
If you want to use it, just download our binary relase from [https://www.paraview.org/download/](https://www.paraview.org/download/)

Hello, just noticed the MEDReader is not in the 6.1.1 binary build for ARM64. Is it possible to add it?

If you mean macOS arm64, I’m afraid the med stack is not compatible with macOS yet, but it coudl be improved on that regard.
