-  <title>Introduction</title>
-  <para>
-    "Cross-compilation" means compiling a program on one machine for another type of machine.
-    For example, a typical use of cross compilation is to compile programs for embedded devices.
-    These devices often don't have the computing power and memory to compile their own programs.
-    One might think that cross-compilation is a fairly niche concern, but there are advantages to being rigorous about distinguishing build-time vs run-time environments even when one is developing and deploying on the same machine.
-    Nixpkgs is increasingly adopting this opinion in that packages should be written with cross-compilation in mind, and nixpkgs should evaluate in a similar way (by minimizing cross-compilation-specific special cases) whether or not one is cross-compiling.
-  </para>
-
-  <para>
-    This chapter will be organized in three parts.
-    First, it will describe the basics of how to package software in a way that supports cross-compilation.
-    Second, it will describe how to use Nixpkgs when cross-compiling.
-    Third, it will describe the internal infrastructure supporting cross-compilation.

-    <para>
-      The three GNU Autoconf platforms, <wordasword>build</wordasword>, <wordasword>host</wordasword>, and <wordasword>cross</wordasword>, are historically the result of much confusion.
-      <link xlink:href="https://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html" /> clears this up somewhat but there is more to be said.
-      An important advice to get out the way is, unless you are packaging a compiler or other build tool, just worry about the build and host platforms.
-      Dealing with just two platforms usually better matches people's preconceptions, and in this case is completely correct.
-    </para>
-    <para>
-      In Nixpkgs, these three platforms are defined as attribute sets under the names <literal>buildPlatform</literal>, <literal>hostPlatform</literal>, and <literal>targetPlatform</literal>.
-      All are guaranteed to contain at least a <varname>platform</varname> field, which contains detailed information on the platform.
-      All three are always defined at the top level, so one can get at them just like a dependency in a function that is imported with <literal>callPackage</literal>:
-      <programlisting>{ stdenv, buildPlatform, hostPlatform, fooDep, barDep, .. }: ...</programlisting>
-    </para>
-    <warning><para>
-      These platforms should all have the same structure in all scenarios, but that is currently not the case.
-      When not cross-compiling, they will each contain a <literal>system</literal> field with a short 2-part, hyphen-separated summering string name for the platform.
-      But, when when cross compiling, <literal>hostPlatform</literal> and <literal>targetPlatform</literal> may instead contain <literal>config</literal> with a fuller 3- or 4-part string in the manner of LLVM.
-      We should have all 3 platforms always contain both, and maybe give <literal>config</literal> a better name while we are at it.

-            The "target platform" is black sheep.
-            The other two intrinsically apply to all compiled software—or any build process with a notion of "build-time" followed by "run-time".
-            The target platform only applies to programming tools, and even then only is a good for for some of them.
-            Briefly, GCC, Binutils, GHC, and certain other tools are written in such a way such that a single build can only compiler code for a single platform.
-            Thus, when building them, one must think ahead about what platforms they wish to use the tool to produce machine code for, and build binaries for each.
-          </para>
-          <para>
-            There is no fundamental need to think about the target ahead of time like this.
-            LLVM, for example, was designed from the beginning with cross-compilation in mind, and so a normal LLVM binary will support every architecture that LLVM supports.
-            If the tool supports modular or pluggable backends, one might imagine specifying a <emphasis>set</emphasis> of target platforms / backends one wishes to support, rather than a single one.
-          </para>
-          <para>
-            The biggest reason for mess, if there is one, is that many compilers have the bad habit a build process that builds the compiler and standard library/runtime together.
-            Then the specifying target platform is essential, because it determines the host platform of the standard library/runtime.
-            Nixpkgs tries to avoid this where possible too, but still, because the concept of a target platform is so ingrained now in Autoconf and other tools, it is best to support it as is.
-            Tools like LLVM that don't need up-front target platforms can safely ignore it like normal packages, and it will do no harm.

-    <title>Specifying Dependencies</title>
-    <para>
-      As mentioned in the introduction to this chapter, one can think about a build time vs run time distinction whether cross-compiling or not.
-      In the case of cross-compilation, this corresponds with whether a derivation running on the native or foreign platform is produced.
-      An interesting thing to think about is how this corresponds with the three Autoconf platforms.
-      In the run-time case, the depending and depended-on package simply have matching build, host, and target platforms.
-      But in the build-time case, one can imagine "sliding" the platforms one over.
-      The depended-on package's host and target platforms (respectively) become the depending package's build and host platforms.
-      This is the most important guiding principle behind cross-compilation with Nixpkgs, and will be called the <wordasword>sliding window principle</wordasword>.
-      In this manner, given the 3 platforms for one package, we can determine the three platforms for all its transitive dependencies.
-    </para>
-    <para>
-      Some examples will probably make this clearer.
-      If a package is being built with a <literal>(build, host, target)</literal> platform triple of <literal>(foo, bar, bar)</literal>, then its build-time dependencies would have a triple of <literal>(foo, foo, bar)</literal>, and <emphasis>those packages'</emphasis> build-time dependencies would have triple of <literal>(foo, foo, foo)</literal>.
-      In other words, it should take two "rounds" of following build-time dependency edges before one reaches a fixed point where, by the sliding window principle, the platform triple no longer changes.
-      Indeed, this happens with cross compilation, where only rounds of native dependencies starting with the second necessarily coincide with native packages.
-    </para>
-    <note><para>
-      The depending package's target platform is unconstrained by the sliding window principle, which makes sense in that one can in principle build cross compilers targeting arbitrary platforms.
-    </para></note>
-    <para>
-      How does this work in practice? Nixpkgs is now structured so that build-time dependencies are taken from from <varname>buildPackages</varname>, whereas run-time dependencies are taken from the top level attribute set.
-      For example, <varname>buildPackages.gcc</varname> should be used at build time, while <varname>gcc</varname> should be used at run time.
-      Now, for most of Nixpkgs's history, there was no <varname>buildPackages</varname>, and most packages have not been refactored to use it explicitly.
-      Instead, one can use the four attributes used for specifying dependencies as documented in <link linkend="ssec-stdenv-attributes" />.
-      We "splice" together the run-time and build-time package sets with <varname>callPackage</varname>, and then <varname>mkDerivation</varname> for each of four attributes pulls the right derivation out.
-      This splicing can be skipped when not cross compiling as the package sets are the same, but is a bit slow for cross compiling.
-      Because of this, a best-of-both-worlds solution is in the works with no splicing or explicit access of <varname>buildPackages</varname> needed.
-      For now, feel free to use either method.

-    More information needs to moved from the old wiki, especially <link xlink:href="https://nixos.org/wiki/CrossCompiling" />, for this section.
-  </para></note>
-  <para>
-    Many sources (manual, wiki, etc) probably mention passing <varname>system</varname>, <varname>platform</varname>, and, optionally, <varname>crossSystem</varname> to nixpkgs:
-    <literal>import &lt;nixpkgs&gt; { system = ..; platform = ..; crossSystem = ..; }</literal>.
-    <varname>system</varname> and <varname>platform</varname> together determine the system on which packages are built, and <varname>crossSystem</varname> specifies the platform on which packages are ultimately intended to run, if it is different.
-    This still works, but with more recent changes, one can alternatively pass <varname>localSystem</varname>, containing <varname>system</varname> and <varname>platform</varname>, for symmetry.
-  </para>
-  <para>
-    One would think that <varname>localSystem</varname> and <varname>crossSystem</varname> overlap horribly with the three <varname>*Platforms</varname> (<varname>buildPlatform</varname>, <varname>hostPlatform,</varname> and <varname>targetPlatform</varname>; see <varname>stage.nix</varname> or the manual).
-    Actually, those identifiers are purposefully not used here to draw a subtle but important distinction:
-    While the granularity of having 3 platforms is necessary to properly *build* packages, it is overkill for specifying the user's *intent* when making a build plan or package set.
-    A simple "build vs deploy" dichotomy is adequate: the sliding window principle described in the previous section shows how to interpolate between the these two "end points" to get the 3 platform triple for each bootstrapping stage.
-    That means for any package a given package set, even those not bound on the top level but only reachable via dependencies or <varname>buildPackages</varname>, the three platforms will be defined as one of <varname>localSystem</varname> or <varname>crossSystem</varname>, with the former replacing the latter as one traverses build-time dependencies.
-    A last simple difference then is <varname>crossSystem</varname> should be null when one doesn't want to cross-compile, while the <varname>*Platform</varname>s are always non-null.
-    <varname>localSystem</varname> is always non-null.

-### Building GHC with integer-simple
-
-By default GHC implements the Integer type using the
-[GNU Multiple Precision Arithmetic (GMP) library](https://gmplib.org/).
-The implementation can be found in the
-[integer-gmp](http://hackage.haskell.org/package/integer-gmp) package.
-
-A potential problem with this is that GMP is licensed under the
-[​GNU Lesser General Public License (LGPL)](http://www.gnu.org/copyleft/lesser.html),
-a kind of "copyleft" license. According to the terms of the LGPL, paragraph 5,
-you may distribute a program that is designed to be compiled and dynamically
-linked with the library under the terms of your choice (i.e., commercially) but
-if your program incorporates portions of the library, if it is linked
-statically, then your program is a "derivative"--a "work based on the
-library"--and according to paragraph 2, section c, you "must cause the whole of
-the work to be licensed" under the terms of the LGPL (including for free).
-
-The LGPL licensing for GMP is a problem for the overall licensing of binary
-programs compiled with GHC because most distributions (and builds) of GHC use
-static libraries. (Dynamic libraries are currently distributed only for OS X.)
-The LGPL licensing situation may be worse: even though
-​[The Glasgow Haskell Compiler License](https://www.haskell.org/ghc/license)
-is essentially a "free software" license (BSD3), according to
-paragraph 2 of the LGPL, GHC must be distributed under the terms of the LGPL!
-
-To work around these problems GHC can be build with a slower but LGPL-free
-alternative implemention for Integer called
-[integer-simple](http://hackage.haskell.org/package/integer-simple).
-
-To get a GHC compiler build with `integer-simple` instead of `integer-gmp` use
-the attribute: `pkgs.haskell.compiler.integer-simple."${ghcVersion}"`.
-For example:
-
-    $ nix-build -E '(import <nixpkgs> {}).pkgs.haskell.compiler.integer-simple.ghc802'
-    ...
-    $ result/bin/ghc-pkg list | grep integer
-        integer-simple-0.1.1.1
-
-The following command displays the complete list of GHC compilers build with `integer-simple`:
-
-    $ nix-env -f "<nixpkgs>" -qaP -A haskell.compiler.integer-simple
-    haskell.compiler.integer-simple.ghc7102  ghc-7.10.2
-    haskell.compiler.integer-simple.ghc7103  ghc-7.10.3
-    haskell.compiler.integer-simple.ghc722   ghc-7.2.2
-    haskell.compiler.integer-simple.ghc742   ghc-7.4.2
-    haskell.compiler.integer-simple.ghc763   ghc-7.6.3
-    haskell.compiler.integer-simple.ghc783   ghc-7.8.3
-    haskell.compiler.integer-simple.ghc784   ghc-7.8.4
-    haskell.compiler.integer-simple.ghc801   ghc-8.0.1
-    haskell.compiler.integer-simple.ghc802   ghc-8.0.2
-    haskell.compiler.integer-simple.ghcHEAD  ghc-8.1.20170106
-
-To get a package set supporting `integer-simple` use the attribute:
-`pkgs.haskell.packages.integer-simple."${ghcVersion}"`. For example
-use the following to get the `scientific` package build with `integer-simple`:
-
-    $ nix-build -A pkgs.haskell.packages.integer-simple.ghc802.scientific

-To install the rust compiler and cargo put
-
-```
-rustStable.rustc
-rustStable.cargo
-```
-
-into the `environment.systemPackages` or bring them into scope with
-`nix-shell -p rustStable.rustc -p rustStable.cargo`.
-
-There are also `rustBeta` and `rustNightly` package sets available.
-These are not updated very regulary. For daily builds see
-[Using the Rust nightlies overlay](#using-the-rust-nightlies-overlay)
-
-## Packaging Rust applications
-
-Rust applications are packaged by using the `buildRustPackage` helper from `rustPlatform`:
-
-```
-with rustPlatform;
-
-buildRustPackage rec {
-  name = "ripgrep-${version}";
-  version = "0.4.0";
-
-  src = fetchFromGitHub {
-    owner = "BurntSushi";
-    repo = "ripgrep";

-    maintainers = [ maintainers.tailhook ];
-    platforms = platforms.all;
-  };
-}
-```
-
-`buildRustPackage` requires a `depsSha256` attribute which is computed over
-all crate sources of this package. Currently it is obtained by inserting a
-fake checksum into the expression and building the package once. The correct
-checksum can be then take from the failed build.
-
-To install crates with nix there is also an experimental project called
-[nixcrates](https://github.com/fractalide/nixcrates).
-
-## Using the Rust nightlies overlay
-
-Mozilla provides an overlay for nixpkgs to bring a nightly version of Rust into scope.
-This overlay can _also_ be used to install recent unstable or stable versions
-of Rust, if desired.
-
-To use this overlay, clone
-[nixpkgs-mozilla](https://github.com/mozilla/nixpkgs-mozilla),
-and create a symbolic link to the file
-[rust-overlay.nix](https://github.com/mozilla/nixpkgs-mozilla/blob/master/rust-overlay.nix)
-in the `~/.config/nixpkgs/overlays` directory.
-
-    $ git clone https://github.com/mozilla/nixpkgs-mozilla.git
-    $ mkdir -p ~/.config/nixpkgs/overlays
-    $ ln -s $(pwd)/nixpkgs-mozilla/rust-overlay.nix ~/.config/nixpkgs/overlays/rust-overlay.nix
-
-The latest version can be installed with the following command:
-
-    $ nix-env -Ai nixos.rustChannels.stable.rust
-
-Or using the attribute with nix-shell:
-
-    $ nix-shell -p nixos.rustChannels.stable.rust
-
-To install the beta or nightly channel, "stable" should be substituted by
-"nightly" or "beta", or
-use the function provided by this overlay to pull a version based on a
-build date.
-
-The overlay automatically updates itself as it uses the same source as
-[rustup](https://www.rustup.rs/).

-# User's Guide to Vim Plugins/Addons/Bundles/Scripts in Nixpkgs
-
-You'll get a vim(-your-suffix) in PATH also loading the plugins you want.
-Loading can be deferred; see examples.
-
-VAM (=vim-addon-manager) and Pathogen plugin managers are supported.
-Vundle, NeoBundle could be your turn.
-
-## dependencies by Vim plugins
-
-VAM introduced .json files supporting dependencies without versioning
-assuming that "using latest version" is ok most of the time.
-
-## HOWTO
-
-First create a vim-scripts file having one plugin name per line. Example:
-
-    "tlib"
-    {'name': 'vim-addon-sql'}
-    {'filetype_regex': '\%(vim)$', 'names': ['reload', 'vim-dev-plugin']}
-
-Such vim-scripts file can be read by VAM as well like this:
-
-    call vam#Scripts(expand('~/.vim-scripts'), {})
-
-Create a default.nix file:
-
-    { nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7102" }:
-    nixpkgs.vim_configurable.customize { name = "vim"; vimrcConfig.vam.pluginDictionaries = [ "vim-addon-vim2nix" ]; }
-
-Create a generate.vim file:
-
-    ActivateAddons vim-addon-vim2nix
-    let vim_scripts = "vim-scripts"
-    call nix#ExportPluginsForNix({
-    \  'path_to_nixpkgs': eval('{"'.substitute(substitute(substitute($NIX_PATH, ':', ',', 'g'), '=',':', 'g'), '\([:,]\)', '"\1"',"g").'"}')["nixpkgs"],
-    \  'cache_file': '/tmp/vim2nix-cache',
-    \  'try_catch': 0,
-    \  'plugin_dictionaries': ["vim-addon-manager"]+map(readfile(vim_scripts), 'eval(v:val)')
-    \ })
-
-Then run
-
-    nix-shell -p vimUtils.vim_with_vim2nix --command "vim -c 'source generate.vim'"
-
-You should get a Vim buffer with the nix derivations (output1) and vam.pluginDictionaries (output2).
-You can add your vim to your system's configuration file like this and start it by "vim-my":
-
-    my-vim =
-     let plugins = let inherit (vimUtils) buildVimPluginFrom2Nix; in {
-          copy paste output1 here
-     }; in vim_configurable.customize {
-       name = "vim-my";
-
-       vimrcConfig.vam.knownPlugins = plugins; # optional
-       vimrcConfig.vam.pluginDictionaries = [
-          copy paste output2 here
-       ];
-
-       # Pathogen would be
-       # vimrcConfig.pathogen.knownPlugins = plugins; # plugins
-       # vimrcConfig.pathogen.pluginNames = ["tlib"];
-     };
-
-
-Sample output1:
-
-    "reload" = buildVimPluginFrom2Nix { # created by nix#NixDerivation
-      name = "reload";
-      src = fetchgit {
-        url = "git://github.com/xolox/vim-reload";
-        rev = "0a601a668727f5b675cb1ddc19f6861f3f7ab9e1";
-        sha256 = "0vb832l9yxj919f5hfg6qj6bn9ni57gnjd3bj7zpq7d4iv2s4wdh";
-      };
-      dependencies = ["nim-misc"];
-
-    };
-    [...]
-
-Sample output2:
-
-    [
-      ''vim-addon-manager''
-      ''tlib''
-      { "name" = ''vim-addon-sql''; }
-      { "filetype_regex" = ''\%(vim)$$''; "names" = [ ''reload'' ''vim-dev-plugin'' ]; }
-    ]
-
-
-## Important repositories
-
-- [vim-pi](https://bitbucket.org/vimcommunity/vim-pi) is a plugin repository
-  from VAM plugin manager meant to be used by others as well used by
-
-- [vim2nix](http://github.com/MarcWeber/vim-addon-vim2nix) which generates the
-  .nix code

-  Steam is distributed as a <filename>.deb</filename> file, for now only

-  </filename>. When run for the first time, this script copies some

-  way to contribute to the project.</para>
-
-<para>The high change rate of nixpkgs make any pull request that is open for 
-  long enough subject to conflicts that will require extra work from the 
-  submitter or the merger. Reviewing pull requests in a timely manner and being 
-  responsive to the comments is the key to avoid these. Github provides sort

-
-<para>GitHub provides reactions, they are a simple and quick way to provide 
-  feedback to pull-requests or any comments. The thumb-down reaction should be 
-  used with care and if possible accompanied with some explanations so the 
-  submitter has directions to improve his contribution.</para>

-    acceptInterface = "br0";
-    bindInterface = "tun1";
-    port = 5912;

-      Autoloading connection tracking helpers is now disabled by default.
-      This default was also changed in the Linux kernel and is considered
-      insecure if not configured properly in your firewall. If you need
-      connection tracking helpers (i.e. for active FTP) please enable

-    Iputils no longer provide ping6 and traceroute6. The functionality of
-    these tools have been integrated into ping and traceroute respectively. To
-    enforce an address family the new flags <literal>-4</literal> and
-    <literal>-6</literal> have been added. One notable incompatibility is that
-    specifying an interface (for link-local IPv6 for instance) is no longer done
-    with the <literal>-I</literal> flag, but by encoding the interface into the
-    address (<literal>ping fe80::1%eth0</literal>).

-      and <literal>bindInetSockets</literal> have been replaced by
-      <literal>services.rmilter.bindSocket.*</literal>. The default is still
-      a unix socket in <literal>/run/rmilter/rmilter.sock</literal>. Refer to
-      the options documentation for more information.

-  </listitem>
-
-  <listitem>
-    <para>
-      The dnscrypt-proxy module interface has been streamlined around the
-      <option>extraArgs</option> option. Where possible, legacy option
-      declarations are mapped to <option>extraArgs</option> but will emit
-      warnings. The <option>resolverList</option> has been outright
-      removed: to use an unlisted resolver, use the
-      <option>customResolver</option> option.
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>
-      torbrowser now stores local state under

-      <literal>jre</literal> now defaults to GTK+ UI by default. This
-      improves visual consistency and makes Java follow system font style,
-      improving the situation on HighDPI displays. This has a cost of increased
-      closure size; for server and other headless workloads it's recommended to
-      use <literal>jre_headless</literal>.

-    <para>Python 2.6 interpreter and package set have been removed.</para>
-  </listitem>

-    <para>
-      The Python 2.7 interpreter does not use modules anymore. Instead, all

-      which is available in the Python package set.
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>
-      Python 2.7, 3.5 and 3.6 are now built deterministically and 3.4 mostly.
-      Minor modifications had to be made to the interpreters in order to generate
-      deterministic bytecode. This has security implications and is relevant for
-      those using Python in a <literal>nix-shell</literal>. See the Nixpkgs manual
-      for details.
-    </para>
-  </listitem>
-
-  <listitem>

-  </listitem>
-
-  <listitem>
-    <para>
-      The Python function <literal>buildPythonPackage</literal> has been improved and can be
-      used to build from Setuptools source, Flit source, and precompiled Wheels.
-    </para>
-  </listitem>

-      When adding new or updating current Python libraries, the expressions should be put

-    <para>
-      The dnscrypt-proxy service supports synchronizing the list of public
-      resolvers without working DNS resolution. This fixes issues caused by the
-      resolver list becoming outdated. It also improves the viability of
-      DNSCrypt only configurations.
-    </para>
