flake.nix (4733B)
1 # This is a nix flake. To use it, you need nix (with flake support) installed. 2 # If you do not have nix and do not intend to use it, you can ignore this file. 3 # Why should you use it? Using this flake will allow you to enter a developer shell 4 # which has all necessary packages for this repository already installed. 5 # The shell will allow you to code against the specific revisions of the dependencies 6 # pinned in this file. 7 # This is useful when git HEAD of your dependencies already contains breaking changes 8 # you should not (yet) code against. 9 # OTOH, if you should code against a newer, not yet released revision, you can specify 10 # this revision in this file. 11 # You can use this file in three ways: 12 # 1. Build: $ nix build 13 # this will build the package (it runs make for you in an environment with the dependencies installed) 14 # 2. Develop: $ nix develop 15 # This will drop you inside a shell in which you can develop and compile (and test) your code. 16 # It even starts and sets up the test database for you. 17 # 3. Use this repository in a new project 18 # Should you create a new project that depends on this project you are in luck. You can create a flake.nix 19 # in your repository and include this packages as a dependency just like the dependencies of this package are 20 # included here. 21 22 { 23 inputs = { 24 nixpkgs.url = "nixpkgs/release-25.11"; 25 systems.url = "github:nix-systems/default"; 26 gnunet.url = "git+https://git.gnunet.org/gnunet?rev=7c6b613e37e301b0e81fb94af5878d00c98e5b75"; 27 exchange.url = "git+https://git.gnunet.org/exchange?rev=7bdeb39e06b604936e02990becad696d3f82c201"; 28 merchant.url = "git+https://git.gnunet.org/merchant?rev=b174138726171601b666fff346762502be5150a1"; 29 donau.url = "git+https://git.gnunet.org/donau?rev=4f609168fe263891f134eff01f86288066acdd81"; 30 self.submodules = true; 31 }; 32 33 outputs = { self, nixpkgs, gnunet, exchange, donau, merchant, systems, ... } @ inputs: 34 let 35 supportedSystems = [ "x86_64-linux" "x86_64-darwin" "aarch64-linux" "aarch64-darwin" ]; 36 forEachSystem = nixpkgs.lib.genAttrs supportedSystems; 37 nixpkgsFor = forEachSystem (system: import nixpkgs { inherit system; }); 38 in 39 { 40 # This defines (installable) package derivations 41 # For use in flakes that use this flake as input in order 42 # to specify/use this package from git as a dependency 43 packages = forEachSystem (system: 44 let 45 pkgs = nixpkgsFor.${system}; 46 gnunetpkgs = gnunet.packages.${system}; 47 exchangepkgs = exchange.packages.${system}; 48 donaupkgs = donau.packages.${system}; 49 merchantpkgs = merchant.packages.${system}; 50 in { 51 paivana = pkgs.stdenv.mkDerivation { 52 name = "paivana"; 53 src = ./.; 54 nativeBuildInputs = [ 55 pkgs.gnumake 56 pkgs.meson 57 pkgs.ninja 58 pkgs.pkg-config 59 ]; 60 buildInputs = [ 61 pkgs.libtool 62 pkgs.jansson 63 pkgs.git 64 pkgs.libmicrohttpd 65 pkgs.libgcrypt 66 pkgs.curlWithGnuTls 67 gnunetpkgs.gnunet 68 exchangepkgs.exchange 69 donaupkgs.donau 70 merchantpkgs.merchant 71 ]; 72 preConfigure = '' 73 patchShebangs --build contrib/check-prebuilt 74 ./bootstrap 75 ''; 76 }; 77 } 78 ); 79 defaultPackage = forEachSystem (system: self.packages.${system}.paivana); 80 # This defines a development shell in which you can compile 81 # (and use) exchange 82 devShells = forEachSystem 83 (system: 84 let 85 pkgs = nixpkgsFor.${system}; 86 gnunetpkgs = gnunet.packages.${system}; 87 exchangepkgs = exchange.packages.${system}; 88 donaupkgs = donau.packages.${system}; 89 merchantpkgs = merchant.packages.${system}; 90 in 91 { 92 default = pkgs.mkShell { 93 packages = [ 94 pkgs.gcc 95 pkgs.meson 96 pkgs.ninja 97 pkgs.gnumake 98 pkgs.pkg-config 99 pkgs.libtool 100 pkgs.jansson 101 pkgs.git 102 pkgs.curlWithGnuTls 103 gnunetpkgs.gnunet 104 pkgs.codespell 105 pkgs.clang-tools 106 pkgs.uncrustify 107 exchangepkgs.exchange 108 donaupkgs.donau 109 merchantpkgs.merchant 110 ]; 111 112 shellHook = '' 113 echo "paivana environment loaded." 114 export CC=gcc 115 export CFLAGS="-O" 116 ''; 117 }; 118 }); 119 }; 120 }
