Add nix derivation #45
Conversation
Convenience for NixOS / Nixpkgs users, `nix-build` ran in main project directory should build this and create a `result/` symlink pointing at a built package.

Thanks, but keep in mind that I don't have a CI/Environment to test NixOS. |

Thanks for your contribution. Apart from my other comments: What's the reason for using a default.nix instead of making it a Flake?
Note that I'm not involved with this project, just stumbled on the project when trying to reverse-engineer some firmware and saw your pull request.

This needs to be in nativeBuildInputs because otherwise you'll get cmake for the target platform when cross-compiling.

No need to specify .dev since this output is already used by default for buildInputs.

If you place cmake in nativeBuildInputs, you get the right setup hooks and won't need this.

It's the upstream project, so no need to fix up something like this.

This is pretty ugly IMO and those files ideally should be in $out/share/epk2extract or something like that but certainly not in $out/bin. Probably it's a good idea to make this configurable (see src/main.c:223) via cmake.

I know it's probably personal taste, but what about the following (which does not change the current working directory):
| mkdir -p $out/bin | |
| cd src | |
| cp epk2extract tools/lzhsenc tools/lzhs_scanner tools/idb_extract tools/jffs2extract $out/bin | |
| for i in src/epk2extract src/tools/{lzhsenc,lzhs_scanner,idb_extract,jffs2extract}; do | |
| install -vD "$i" "$out/bin/$(basename "$i")" | |
| done |

Since we don't have an explicit version here, it's probably better to just use name instead of pname and version:
| pname = "epk2extract"; | |
| version = "devel"; | |
| name = "epk2extract"; |

Just a small nitpick:

Just a very simple reason - I just haven't started using Flakes yet :D Thank you very much for a review. As you may have guessed, I am not very well versed in practical nix packaging. I'll integrate the changes this weekend. |
