Hello there! I’m trying to just do a channel update and then rebuild with sudo nixos-rebuild switch but:

make[1]: *** [CMakeFiles/Makefile2:1052: CMakeFiles/pdalcpp.dir/all] Error 2

I am (if it wasn’t obvious) not the most NixOS versed, but I am too good for myself to use AI for something like this, so I’d really appreciate some help!

Thanks in advance!!

I’m assuming you are on nixos-unstable, where pdal is currently failing to build.

Either:

  • wait for Nixpkgs Tracker to show the PR updating the pdal version to land in nixos-unstable. Honestly, I’d probably recommend this one.
  • if it’s critical to you that you be able to update your system to a new nixpkgs for some reason
    • patch/overlay your pkgs to incorporate the version change and build pdal locally
    • OR remove pdal and downstream friends from your config, then write a shell.nix/other devshell that pins nixpkgs to a version of nixpkgs where pdal and friends do successfully build and use that for this software in the meantime
    • OR mix multiple versionsof nixpkgs, supplying pdal+friends from a “known good” nixpkgs for that package. If you search this forum for how to mix stable and unstable channels that should basically cover the idea

Yes, i am on nixos-unstable. With the option of waiting it out, are we talking about a week or more time? if it will be just a matter of a day or a few, waiting would also be my favourite pick.

Given that it’s already hit nixos-unstable-small. I would guess a few days to a week, but it’s kinda up to hydra which means a bit of a combination of capacity and luck for the exact timeline
