flake.nix (5222B)
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-26.05"; 25 systems.url = "github:nix-systems/default"; 26 gnunet.url = "git+https://git.gnunet.org/gnunet?rev=e8e7504b7ab43f7dffa25f273ff228069d8d6dd4"; 27 exchange.url = "git+https://git.gnunet.org/exchange?rev=b542c0c40c30e1ddd9b0528e913cceed8eef9c56"; 28 merchant.url = "git+https://git.gnunet.org/merchant?rev=8ca128478cf6dd8524572bf4fb344abde24ea34e"; 29 donau.url = "git+https://git.gnunet.org/donau?rev=014bf263a4f4631cfbab6486a3af069524e98ec6"; 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.${system}; 50 in { 51 paivana = pkgs.stdenv.mkDerivation { 52 name = "paivana"; 53 src = ./.; 54 nativeBuildInputs = [ 55 pkgs.gnumake 56 pkgs.meson 57 pkgs.ninja 58 pkgs.pkg-config 59 # src/frontend/generate-paywall.py renders the paywall 60 # template at build time and needs jinja2. 61 (pkgs.python3.withPackages (ps: [ ps.jinja2 ])) 62 ]; 63 buildInputs = [ 64 pkgs.libtool 65 pkgs.jansson 66 pkgs.git 67 pkgs.libmicrohttpd 68 pkgs.libgcrypt 69 pkgs.curlWithGnuTls 70 gnunetpkgs.gnunet 71 exchangepkgs.exchange 72 donaupkgs.donau 73 merchantpkgs.merchant 74 ]; 75 preConfigure = '' 76 patchShebangs --build bootstrap configure scripts src/frontend src/tests 77 ./bootstrap 78 ''; 79 }; 80 } 81 ); 82 defaultPackage = forEachSystem (system: self.packages.${system}.paivana); 83 # This defines a development shell in which you can compile 84 # (and use) exchange 85 devShells = forEachSystem 86 (system: 87 let 88 pkgs = nixpkgsFor.${system}; 89 gnunetpkgs = gnunet.packages.${system}; 90 exchangepkgs = exchange.packages.${system}; 91 donaupkgs = donau.packages.${system}; 92 merchantpkgs = merchant.packages.${system}; 93 in 94 { 95 default = pkgs.mkShell { 96 # Keep this in step with the buildInputs above: a shell 97 # that cannot get past ./configure is worse than no shell. 98 packages = [ 99 pkgs.gcc 100 pkgs.meson 101 pkgs.ninja 102 pkgs.gnumake 103 pkgs.pkg-config 104 pkgs.libtool 105 pkgs.jansson 106 pkgs.libmicrohttpd 107 pkgs.libgcrypt 108 pkgs.git 109 pkgs.curlWithGnuTls 110 (pkgs.python3.withPackages (ps: [ ps.jinja2 ])) 111 gnunetpkgs.gnunet 112 pkgs.codespell 113 pkgs.clang-tools 114 pkgs.uncrustify 115 exchangepkgs.exchange 116 donaupkgs.donau 117 merchantpkgs.merchant 118 ]; 119 120 shellHook = '' 121 echo "paivana environment loaded." 122 export CC=gcc 123 export CFLAGS="-O" 124 ''; 125 }; 126 }); 127 }; 128 }
