edolstra / dwarffs Goto Github PK

While trying to use this I discovered that the README is outdated since it doesn't yet talk about flakes and the module.nix had been (re)moved in 2f984ab.

Hi, I pull this into my flake, and attempting to update my lock fails with master because nixFlakes in nixos/nixpkgs/master is now around a month old. If there isn't any significant difference, could the flake.lock in this be monkeypatched to version 4? Alternatively (and preferably), could the version in nixpkgs be updated?

this commit on nix broke compilation since dwarffs uses stringToInt to parse some arguments.

At least in my flake, using d11b181 or later results in this:

My fault or yours? :p

Without it, it falls under All rights reserved and we cannot use it.

Steps to reproduce:

1. nix flake update --commit-lock-file
2. nix build

Observed error:

error: attribute 'overlay' missing

Hi, I added dwarffs as described to my configuration.nix, but I get the following error:

attribute ‘fetchgit’ missing, at

Any ideas what I could miss?

Are there instructions on how to use this project as a package, not as a nixOS module?

Also, when I do nix shell github:edolstra/dwarffs --command dwarffs --help, I get a core.

I would really like to use DwarfFS so that I can turn off global debug packages for my system -- not having symbols at debug time is pretty much the only reason to enable it!

However, 2f984ab inlined the module.nix file into the new flake description. I understand the desire to use self-contained tools like dwarffs for experimenting with Flakes, but I'm not running the Flake branch, and dwarffs is useful without it!

I'd like to propose re-adding the old module.nix file so DwarfFS can be used by non-flake users without writing their own. I do not know if code reuse is possible, but I don't think it's worth it for such a conceptually simple expression.

Alternatively, packaging dwarffs upstream inside Nixpkgs would also be great IMO, but I understand if you don't want to do that since it'll directly conflict with the flake experiment...

Ive noticed that a lot of programs expect debuginfo to be in /usr/lib/debug/.build-id/..., would a declarative symlink for this be possible?

The build fails as:

g++ -c -g -std=c++17 -Wall -Os dwarffs.cc -o dwarffs.o
dwarffs.cc:10:10: fatal error: fs-accessor.hh: No such file or directory
   10 | #include "fs-accessor.hh"
      |          ^~~~~~~~~~~~~~~~
compilation terminated.

Possibly caused by NixOS/nix@1a902f5

How to use this on NixOS-20.09? What do I need to add to my configuration.nix to enable this?
