=== Explicit Dependencies === | |||
However 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: | |||
<syntaxHighlight lang=nix> | |||
# shell.nix | |||
{ pkgs ? import <nixpkgs> {} }: | |||
let | |||
# pkgs.qt6.env already includes pkgs.qt6.qtbase | |||
# And using `with` to prevent a lot of typing. | |||
qtEnv = with pkgs.qt6; env "qt-custom-${qtbase.version}" { | |||
[ | |||
qtdeclarative | |||
] | |||
}; | |||
in | |||
pkgs.mkShell { | |||
buildInputs = [ | |||
qtEnv | |||
# pkgs.qt6.qtdeclarative depends on pkgs.libglvnd | |||
# Also worth noting it could be in qtEnv if preferred for "relatedness" reasons | |||
pkgs.libglvnd | |||
pkgs.qtcreator | |||
]; | |||
} | |||
