Installation instructions - applying the overlay #46

Closed argit2 closed 4 years ago

argit2 commented 4 years ago

I'm a total noob at nix, installed it just for this package. After a lot of time I finally figured I had to ran nix-build to build the program and it was successful. The program runs if I use its full path, but it doesn't detect ffmpeg since I couldn't follow the install instructions to set up the nix-env.

I have no idea how to apply the overlay. Maybe something changed about nix or how nix deals with haskell packages.

I've tried multiple things, including going to ./nix/overlay and running nix-build since there's a default.nix (which i assume is there to apply the overlay contained in haskellPackages.nix), but I get the error: error: expression does not evaluate to a derivation (or a set or list of those) Copying neither, either or both .nix in the overlay folder to ~/.config/nixpkgs either gives an error error: attribute 'cut-the-crap' in selection path 'cut-the-crap' not found or a problem with recursion error: infinite recursion encountered, at undefined position

Am I doing it wrong or is there an actual error going on? Can you please provide clearer installation instructions for beginners like me?

Hi, I see the confusion, the install instructions were outdated because it has become a lot easier these days. I added additional instructions and fixed the top level default.nix to make it ffmpeg aware.

Thanks for reaching out! I have the program also hosted as a service now: http://videocut.org/ I just made that work yesterday!

This shouldn't be necessary anymore. but it involves changing the config in nixpkgs: https://github.com/jappeace/linux-config/blob/work-machine/configuration.nix#L9 But you shouldn't have to do this I think

Now it works! Thanks.
