Hello, this may be a dumb question but I am completely stuck:
I wanted to try out dwm as window manager, using a local config.def.h file.
I followed the advice in the wiki:
environment.systemPackages = with pkgs; [
(dwm.overrideAttrs (oldAttrs: rec {
configFile = writeText "config.def.h" (builtins.readFile /home/someone/Software/dwm/config.def.h);
postPatch = oldAttrs.postPatch ++ ''cp ${configFile} config.def.h'';
}))
];
But when I do nixos-rebuild test
he fails with:
error: attribute 'postPatch' missing, at /etc/nixos/xserver-config.nix:6:19
Which is weird, since the ‘postPatch’ attribute is present.
Any Ideas ?
