我正在尝试从fokus (a KDE plasmoid)派生。
我有一个default.nix看起来像：
{ mkDerivation, lib, fetchFromGitLab, cmake, extra-cmake-modules
, plasma-framework
, qt5 }:
let
version = "1.5.4";
repo = fetchFromGitLab {
owner = "divinae";
repo = "focus-plasmoid";
rev = "v${version}";
sha256 = "19nndmqfzdcg7lzcifxa17m2mx85dlf4m2wxzr72gf78h4yj0ahv";
};
in
mkDerivation rec {
inherit version;
pname = "fokus";
src = "${repo}/packages";
dontUnpack = true;
buildInputs = [
plasma-framework
qt5.qtbase
];
nativeBuildInputs = [ cmake extra-cmake-modules ];
meta = with lib; {
description = "Simple pomodoro timer plasmoid";
homepage = "https://store.kde.org/p/1308861/";
license = licenses.gpl3Only;
maintainers = with maintainers; [ ];
platforms = platforms.unix;
};
}
我还添加到all-packages：
fokus-plasma-applet = libsForQt5.callPackage ../applications/misc/fokus-plasma-applet { };
问题是，我在 nixpkgs 中只找到了几个例子，我不知道如何处理这个错误（因为CMakeLists.txt实际上是在/package）：
