NS-3

I saw you use NS-3 with nixos yourself.

You got a nix config to make a build work?

For me it doesn't find packages like eigen, doxygen, sqlite eventhough they are installed (sqlite3 -version f.e. works).

Would love catching up with you noel@huibers.io for email contact. Noel (talk) 16:50, 8 November 2024 (UTC)

I don't use it, You can override the package to enable the various options https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/science/networking/ns-3/default.nix or overrideAttrs to add eigen

Dunno about sqlite, maybe you need to include it in your own build, if you just have the package in your systemPackages it won't have the dev output and so no libraries

the package itself finds sqlite https://hydra.nixos.org/build/279506411/nixlog/2 Artturin (talk) 17:42, 21 November 2024 (UTC)

Why is callPackage used?

Using packages directly from `pkgs` will not work properly with cross-compilation, instead the packages should be gotten from `pkgs.__splicedPackages` (packages will have `__spliced` attr) which allows stdenv to pick the correct offset dependency for the dependency attributes. `callPackage` gets packages from `__splicedPackages` Artturin (talk) 23:44, 2 April 2025 (UTC)
