Qt: Difference between revisions

For using direnv, create a '''shell.nix''' file in the root of your project and paste these lines into it:

{ pkgs ? import <nixpkgs> {} }:

   pkgs.mkShell {

       pkgs.qtcreator

     ];

Also, create '''.envrc''' file and paste: <code>use_nix</code> into it.

If fetching the entirety of <code>pkgs.qt6.full</code> is not appealing and you know which parts of Qt you need, your first instinct might be adding something like <code>pkgs.qt6.qtdeclarative</code> for creating QML-based Qt programs to <code>buildInputs</code>, '''however''' that will not work and you will get compile errors for missing libraries. <code>pkgs.qt6.full</code> is actually [https://github.com/NixOS/nixpkgs/blob/nixos-24.11/pkgs/development/libraries/qt-6/default.nix#L94-L144 creating an environment that contains all Qt libraries] that allows <code>qmake</code> and tools to find those libraries, so you must do the same and <code>pkgs.qt6.env</code> will help make one. For example:

{ pkgs ? import <nixpkgs> {} }:

let

       pkgs.qtcreator

     ];

For actual python applications, you may also use something like that (to test) :

python3.pkgs.buildPythonApplication {

   pname = "blabla";
