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.

<title>Platform parameters</title>
<para>
The three GNU Autoconf platforms, <wordasword>build</wordasword>, <wordasword>host</wordasword>, and <wordasword>target</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.
Nixpkgs follows the <link xlink:href="https://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html">common historical convention of GNU autoconf</link> of distinguishing between 3 types of platform: <wordasword>build</wordasword>, <wordasword>host</wordasword>, and <wordasword>target</wordasword>.
In summary, <wordasword>build</wordasword> is the platform on which a package is being built, <wordasword>host</wordasword> is the platform on which it is to run. The third attribute, <wordasword>target</wordasword>, is relevant only for certain specific compilers and build tools.
</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 three are always defined as attributes in the standard environment, and at the top level. That means one can get at them just like a dependency in a function that is imported with <literal>callPackage</literal>:

<listitem>
<para>
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 compile code for a single platform.
Thus, when building them, one must think ahead about which platforms they wish to use the tool to produce machine code for, and build binaries for each.
The "target platform" attribute is, unlike the other two attributes, not actually fundamental to the process of building software.
Instead, it is only relevant for compatibility with building certain specific compilers and build tools.
It can be safely ignored for all other packages.
</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.
The build process of certain compilers is written in such a way that the compiler resulting from a single build can itself only produce binaries for a single platform.
The task specifying this single "target platform" is thus pushed to build time of the compiler.
The root cause of this mistake is often that the compiler (which will be run on the host) and the the standard library/runtime (which will be run on the target) are built by a single build process.
</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.
There is no fundamental need to think about a single target ahead of time like this.
If the tool supports modular or pluggable backends, both the need to specify the target at build time and the constraint of having only a single target disappear.
An example of such a tool is LLVM.
</para>
<para>
Although the existance of a "target platfom" is arguably a historical mistake, it is a common one: examples of tools that suffer from it are GCC, Binutils, GHC and Autoconf.
Nixpkgs tries to avoid sharing in the mistake where possible.
Still, because the concept of a target platform is so ingrained, it is best to support it as is.

<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 section we explore the relationship between both runtime and buildtime dependencies and the 3 Autoconf platforms.
</para>
<para>
A runtime dependency between 2 packages implies that between them both the host and target platforms match.
This is directly implied by the meaning of "host platform" and "runtime dependency":
The package dependency exists while both packages are running on a single host platform.
</para>
<para>
A build time dependency, however, implies a shift in platforms between the depending package and the depended-on package.
The meaning of a build time dependency is that to build the depending package we need to be able to run the depended-on's package.
The depending package's build platform is therefore equal to the depended-on package's host platform.
Analogously, the depending package's host platform is equal to the depended-on package's target platform.
</para>
<para>
In this manner, given the 3 platforms for one package, we can determine the three platforms for all its transitive dependencies.
This is the most important guiding principle behind cross-compilation with Nixpkgs, and will be called the <wordasword>sliding window principle</wordasword>.
</para>
<para>
Some examples will probably make this clearer.
@ -177,7 +187,7 @@
How does this work in practice? Nixpkgs is now structured so that build-time dependencies are taken 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 <xref linkend="ssec-stdenv-attributes"/>.
Instead, one can use the six (<emphasis>gasp</emphasis>) attributes used for specifying dependencies as documented in <xref linkend="ssec-stdenv-dependencies"/>.
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.

To install crates with nix there is also an experimental project called
[nixcrates](https://github.com/fractalide/nixcrates).
## Compiling Rust crates using Nix instead of Cargo
When run, `cargo build` produces a file called `Cargo.lock`,
containing pinned versions of all dependencies. Nixpkgs contains a
tool called `carnix` (`nix-env -iA nixos.carnix`), which can be used
to turn a `Cargo.lock` into a Nix expression.
That Nix expression calls `rustc` directly (hence bypassing Cargo),
and can be used to compile a crate and all its dependencies. Here is
an example for a minimal `hello` crate:
$ cargo new hello
$ cd hello
$ cargo build
Compiling hello v0.1.0 (file:///tmp/hello)
Finished dev [unoptimized + debuginfo] target(s) in 0.20 secs
$ carnix -o hello.nix --src ./. Cargo.lock --standalone
$ nix-build hello.nix
Now, the file produced by the call to `carnix`, called `hello.nix`, looks like:
```
with import <nixpkgs> {};
let kernel = buildPlatform.parsed.kernel.name;
# ... (content skipped)
hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
crateName = "hello";
version = "0.1.0";
authors = [ "Authorname <user@example.com>" ];
src = ./.;
inherit dependencies buildDependencies features;
};
in
rec {
hello_0_1_0 = hello_0_1_0_ rec {};
}
```
In particular, note that the argument given as `--src` is copied
verbatim to the source. If we look at a more complicated
dependencies, for instance by adding a single line `libc="*"` to our
`Cargo.toml`, we first need to run `cargo build` to update the
`Cargo.lock`. Then, `carnix` needs to be run again, and produces the
following nix file:
```
with import <nixpkgs> {};
let kernel = buildPlatform.parsed.kernel.name;
# ... (content skipped)
hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
crateName = "hello";
version = "0.1.0";
authors = [ "Jörg Thalheim <joerg@thalheim.io>" ];
src = ./.;
inherit dependencies buildDependencies features;
};
libc_0_2_34_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
crateName = "libc";
version = "0.2.34";
authors = [ "The Rust Project Developers" ];
sha256 = "11jmqdxmv0ka10ay0l8nzx0nl7s2lc3dbrnh1mgbr2grzwdyxi2s";
inherit dependencies buildDependencies features;
};
in
rec {
hello_0_1_0 = hello_0_1_0_ rec {
dependencies = [ libc_0_2_34 ];
};
libc_0_2_34_features."default".from_hello_0_1_0__default = true;
libc_0_2_34 = libc_0_2_34_ rec {
features = mkFeatures libc_0_2_34_features;
};
libc_0_2_34_features."use_std".self_default = hasDefault libc_0_2_34_features;
}
```
Here, the `libc` crate has no `src` attribute, so `buildRustCrate`
will fetch it from [crates.io](https://crates.io). A `sha256`
attribute is still needed for Nix purity.
Some crates require external libraries. For crates from
[crates.io](https://crates.io), such libraries can be specified in
`defaultCrateOverrides` package in nixpkgs itself.
Starting from that file, one can add more overrides, to add features
or build inputs by overriding the hello crate in a seperate file.
```
with import <nixpkgs> {};
(import ./hello.nix).hello_0_1_0.override {
crateOverrides = defaultCrateOverrides // {
hello = attrs: { buildInputs = [ openssl ]; };
};
}
```
Here, `crateOverrides` is expected to be a attribute set, where the
key is the crate name without version number and the value a function.
The function gets all attributes passed to `buildRustCrate` as first
argument and returns a set that contains all attribute that should be
overwritten.
For more complicated cases, such as when parts of the crate's
derivation depend on the the crate's version, the `attrs` argument of
the override above can be read, as in the following example, which
patches the derivation:
```
with import <nixpkgs> {};
(import ./hello.nix).hello_0_1_0.override {
crateOverrides = defaultCrateOverrides // {
hello = attrs: lib.optionalAttrs (lib.versionAtLeast attrs.version "1.0") {
postPatch = ''
substituteInPlace lib/zoneinfo.rs \
--replace "/usr/share/zoneinfo" "${tzdata}/share/zoneinfo"
'';
};
};
}
```
Another situation is when we want to override a nested
dependency. This actually works in the exact same way, since the
`crateOverrides` parameter is forwarded to the crate's
dependencies. For instance, to override the build inputs for crate
`libc` in the example above, where `libc` is a dependency of the main
crate, we could do:
```
with import <nixpkgs> {};
(import hello.nix).hello_0_1_0.override {
crateOverrides = defaultCrateOverrides // {
libc = attrs: { buildInputs = []; };
};
}
```
Three more parameters can be overridden:
- The version of rustc used to compile the crate:
```
hello_0_1_0.override { rust = pkgs.rust; };
```
- Whether to build in release mode or debug mode (release mode by
default):
```
hello_0_1_0.override { release = false; };
```
- Whether to print the commands sent to rustc when building
(equivalent to `--verbose` in cargo:
```
hello_0_1_0.override { verbose = false; };
```
## Using the Rust nightlies overlay
Mozilla provides an overlay for nixpkgs to bring a nightly version of Rust into scope.

title: pkgs.mkShell
author: zimbatm
date: 2017-10-30

pkgs.mkShell is a special kind of derivation that is only useful when using
it combined with nix-shell. It will in fact fail to instantiate when invoked
with nix-build.
## Usage
```nix
{ pkgs ? import <nixpkgs> {} }:
pkgs.mkShell {
# this will make all the build inputs from hello and gnutar available to the shell environment
inputsFrom = with pkgs; [ hello gnutar ];
buildInputs = [ pkgs.gnumake ];
}

<section xml:id="ssec-stdenv-dependencies"><title>Specifying dependencies</title>
<para>
As described in the Nix manual, almost any <filename>*.drv</filename> store path in a derivation's attribute set will induce a dependency on that derivation.
<varname>mkDerivation</varname>, however, takes a few attributes intended to, between them, include all the dependencies of a package.
This is done both for structure and consistency, but also so that certain other setup can take place.
For example, certain dependencies need their bin directories added to the <envar>PATH</envar>.
That is built-in, but other setup is done via a pluggable mechanism that works in conjunction with these dependency attributes.
See <xref linkend="ssec-setup-hooks"/> for details.
</para>
<para>
Dependencies can be broken down along three axes: their host and target platforms relative to the new derivation's, and whether they are propagated.
The platform distinctions are motivated by cross compilation; see <xref linkend="chap-cross"/> for exactly what each platform means.
<footnote><para>
The build platform is ignored because it is a mere implementation detail of the package satisfying the dependency:
As a general programming principle, dependencies are always <emphasis>specified</emphasis> as interfaces, not concrete implementation.
</para></footnote>
But even if one is not cross compiling, the platforms imply whether or not the dependency is needed at run-time or build-time, a concept that makes perfect sense outside of cross compilation.
For now, the run-time/build-time distinction is just a hint for mental clarity, but in the future it perhaps could be enforced.
</para>
<para>
The extension of <envar>PATH</envar> with dependencies, alluded to above, proceeds according to the relative platforms alone.
The process is carried out only for dependencies whose host platform matches the new derivation's build platform–i.e. which run on the platform where the new derivation will be built.
<footnote><para>
Currently, that means for native builds all dependencies are put on the <envar>PATH</envar>.
But in the future that may not be the case for sake of matching cross:
the platforms would be assumed to be unique for native and cross builds alike, so only the <varname>depsBuild*</varname> and <varname>nativeBuildDependencies</varname> dependencies would affect the <envar>PATH</envar>.
</para></footnote>
For each dependency <replaceable>dep</replaceable> of those dependencies, <filename><replaceable>dep</replaceable>/bin</filename>, if present, is added to the <envar>PATH</envar> environment variable.
</para>
<para>
The dependency is propagated when it forces some of its other-transitive (non-immediate) downstream dependencies to also take it on as an immediate dependency.
Nix itself already takes a package's transitive dependencies into account, but this propagation ensures nixpkgs-specific infrastructure like setup hooks (mentioned above) also are run as if the propagated dependency.
</para>
<para>
It is important to note dependencies are not necessary propagated as the same sort of dependency that they were before, but rather as the corresponding sort so that the platform rules still line up.
The exact rules for dependency propagation can be given by assigning each sort of dependency two integers based one how it's host and target platforms are offset from the depending derivation's platforms.
Those offsets are given are given below in the descriptions of each dependency list attribute.
Algorithmically, we traverse propagated inputs, accumulating every propagated dep's propagated deps and adjusting them to account for the "shift in perspective" described by the current dep's platform offsets.
This results in sort a transitive closure of the dependency relation, with the offsets being approximately summed when two dependency links are combined.
We also prune transitive deps whose combined offsets go out-of-bounds, which can be viewed as a filter over that transitive closure removing dependencies that are blatantly absurd.
</para>
<para>
We can define the process precisely with <link xlink:href="https://en.wikipedia.org/wiki/Natural_deduction">Natural Deduction</link> using the inference rules.
This probably seems a bit obtuse, but so is the bash code that actually implements it!
<footnote><para>
The <function>findInputs</function> function, currently residing in <filename>pkgs/stdenv/generic/setup.sh</filename>, implements the propagation logic.
</para></footnote>
They're confusing in very different ways so...hopefully if something doesn't make sense in one presentation, it does in the other!
<programlisting>
let mapOffset(h, t, i) = i + (if i &lt;= 0 then h else t - 1)
propagated-dep(h0, t0, A, B)
propagated-dep(h1, t1, B, C)
h0 + h1 in {-1, 0, 1}
h0 + t1 in {-1, 0, 1}
-------------------------------------- Transitive property
propagated-dep(mapOffset(h0, t0, h1),
mapOffset(h0, t0, t1),
A, C)</programlisting>
<programlisting>
let mapOffset(h, t, i) = i + (if i &lt;= 0 then h else t - 1)
dep(h0, _, A, B)
propagated-dep(h1, t1, B, C)
h0 + h1 in {-1, 0, 1}
h0 + t1 in {-1, 0, -1}
-------------------------------------- Take immediate deps' propagated deps
propagated-dep(mapOffset(h0, t0, h1),
mapOffset(h0, t0, t1),
A, C)</programlisting>
<programlisting>
propagated-dep(h, t, A, B)
-------------------------------------- Propagated deps count as deps
dep(h, t, A, B)</programlisting>
Some explanation of this monstrosity is in order.
In the common case, the target offset of a dependency is the successor to the target offset: <literal>t = h + 1</literal>.
That means that:
<programlisting>
let f(h, t, i) = i + (if i &lt;= 0 then h else t - 1)
let f(h, h + 1, i) = i + (if i &lt;= 0 then h else (h + 1) - 1)
let f(h, h + 1, i) = i + (if i &lt;= 0 then h else h)
let f(h, h + 1, i) = i + h
</programlisting>
This is where the "sum-like" comes from above:
We can just sum all the host offset to get the host offset of the transitive dependency.
The target offset is the transitive dep is simply the host offset + 1, just as it was with the dependencies composed to make this transitive one;
it can be ignored as it doesn't add any new information.
</para>
<para>
Because of the bounds checks, the uncommon cases are <literal>h = t</literal> and <literal>h + 2 = t</literal>.
In the former case, the motivation for <function>mapOffset</function> is that since its host and target platforms are the same, no transitive dep of it should be able to "discover" an offset greater than its reduced target offsets.
<function>mapOffset</function> effectively "squashes" all its transitive dependencies' offsets so that none will ever be greater than the target offset of the original <literal>h = t</literal> package.
In the other case, <literal>h + 1</literal> is skipped over between the host and target offsets.
Instead of squashing the offsets, we need to "rip" them apart so no transitive dependencies' offset is that one.
</para>
<para>
Overall, the unifying theme here is that propagation shouldn't be introducing transitive dependencies involving platforms the needing package is unaware of.
The offset bounds checking and definition of <function>mapOffset</function> together ensure that this is the case.
Discovering a new offset is discovering a new platform, and since those platforms weren't in the derivation "spec" of the needing package, they cannot be relevant.
From a capability perspective, we can imagine that the host and target platforms of a package are the capabilities a package requires, and the depending package must provide the capability to the dependency.

They are programs used at build time that produce code to run at run with code produced by the depending package.
Most commonly, these would tools used to build the runtime or standard library the currently-being-built compiler will inject into any code it compiles.
In many cases, the currently-being built compiler is itself employed for that task, but when that compiler won't run (i.e. its build and host platform differ) this is not possible.
Other times, the compiler relies on some other tool, like binutils, that is always built separately so the dependency is unconditional.
</para>
<para>
This is a somewhat confusing dependency to wrap ones head around, and for good reason.
As the only one where the platform offsets are not adjacent integers, it requires thinking of a bootstrapping stage <emphasis>two</emphasis> away from the current one.
It and it's use-case go hand in hand and are both considered poor form:
try not to need this sort dependency, and try not avoid building standard libraries / runtimes in the same derivation as the compiler produces code using them.
Instead strive to build those like a normal library, using the newly-built compiler just as a normal library would.
In short, do not use this attribute unless you are packaging a compiler and are sure it is needed.

<section xml:id="ssec-setup-hooks"><title>Package setup hooks</title>
<para>The following packages provide a setup hook:
<para>
Nix itself considers a build-time dependency merely something that should previously be built and accessible at build time—packages themselves are on their own to perform any additional setup.
In most cases, that is fine, and the downstream derivation can deal with it's own dependencies.
But for a few common tasks, that would result in almost every package doing the same sort of setup work---depending not on the package itself, but entirely on which dependencies were used.
</para>
<para>
In order to alleviate this burden, the <firstterm>setup hook></firstterm>mechanism was written, where any package can include a shell script that [by convention rather than enforcement by Nix], any downstream reverse-dependency will source as part of its build process.
That allows the downstream dependency to merely specify its dependencies, and lets those dependencies effectively initialize themselves.
No boilerplate mirroring the list of dependencies is needed.
</para>
<para>
The Setup hook mechanism is a bit of a sledgehammer though: a powerful feature with a broad and indiscriminate area of effect.
The combination of its power and implicit use may be expedient, but isn't without costs.
Nix itself is unchanged, but the spirit of adding dependencies being effect-free is violated even if the letter isn't.
For example, if a derivation path is mentioned more than once, Nix itself doesn't care and simply makes sure the dependency derivation is already built just the same—depending is just needing something to exist, and needing is idempotent.
However, a dependency specified twice will have its setup hook run twice, and that could easily change the build environment (though a well-written setup hook will therefore strive to be idempotent so this is in fact not observable).
More broadly, setup hooks are anti-modular in that multiple dependencies, whether the same or different, should not interfere and yet their setup hooks may well do so.
</para>
<para>
The most typical use of the setup hook is actually to add other hooks which are then run (i.e. after all the setup hooks) on each dependency.
For example, the C compiler wrapper's setup hook feeds itself flags for each dependency that contains relevant libaries and headers.
This is done by defining a bash function, and appending its name to one of
<envar>envBuildBuildHooks</envar>`,
<envar>envBuildHostHooks</envar>`,
<envar>envBuildTargetHooks</envar>`,
<envar>envHostHostHooks</envar>`,
<envar>envHostTargetHooks</envar>`, or
<envar>envTargetTargetHooks</envar>`.
These 6 bash variables correspond to the 6 sorts of dependencies by platform (there's 12 total but we ignore the propagated/non-propagated axis).
</para>
<para>
Packages adding a hook should not hard code a specific hook, but rather choose a variable <emphasis>relative</emphasis> to how they are included.
Returning to the C compiler wrapper example, if it itself is an <literal>n</literal> dependency, then it only wants to accumulate flags from <literal>n + 1</literal> dependencies, as only those ones match the compiler's target platform.
The <envar>hostOffset</envar> variable is defined with the current dependency's host offset <envar>targetOffset</envar> with its target offset, before it's setup hook is sourced.
Additionally, since most environment hooks don't care about the target platform,
That means the setup hook can append to the right bash array by doing something like
<programlisting language="bash">
addEnvHooks "$hostOffset" myBashFunction
</programlisting>
</para>
<para>
The <emphasis>existence</emphasis> of setups hooks has long been documented and packages inside Nixpkgs are free to use these mechanism.
Other packages, however, should not rely on these mechanisms not changing between Nixpkgs versions.
Because of the existing issues with this system, there's little benefit from mandating it be stable for any period of time.
</para>
<para>
Here are some packages that provide a setup hook.
Since the mechanism is modular, this probably isn't an exhaustive list.
Then again, since the mechanism is only to be used as a last resort, it might be.

<term>CC Wrapper</term>
<term>Bintools Wrapper</term>
<listitem>
<para>
CC Wrapper wraps a C toolchain for a bunch of miscellaneous purposes.
Specifically, a C compiler (GCC or Clang), Binutils (or the CCTools + binutils mashup when targetting Darwin), and a C standard library (glibc or Darwin's libSystem) are all fed in, and dependency finding, hardening (see below), and purity checks for each are handled by CC Wrapper.
Packages typically depend on only CC Wrapper, instead of those 3 inputs directly.
Bintools Wrapper wraps the binary utilities for a bunch of miscellaneous purposes.
These are GNU Binutils when targetting Linux, and a mix of cctools and GNU binutils for Darwin.
[The "Bintools" name is supposed to be a compromise between "Binutils" and "cctools" not denoting any specific implementation.]
Specifically, the underlying bintools package, and a C standard library (glibc or Darwin's libSystem, just for the dynamic loader) are all fed in, and dependency finding, hardening (see below), and purity checks for each are handled by Bintools Wrapper.
Packages typically depend on CC Wrapper, which in turn (at run time) depends on Bintools Wrapper.
</para>
<para>
Dependency finding is undoubtedly the main task of CC wrapper.
Bintools Wrapper was only just recently split off from CC Wrapper, so the division of labor is still being worked out.
For example, it shouldn't care about about the C standard library, but just take a derivation with the dynamic loader (which happens to be the glibc on linux).
Dependency finding however is a task both wrappers will continue to need to share, and probably the most important to understand.
It is currently accomplished by collecting directories of host-platform dependencies (i.e. <varname>buildInputs</varname> and <varname>nativeBuildInputs</varname>) in environment variables.
CC wrapper's setup hook causes any <filename>include</filename> subdirectory of such a dependency to be added to <envar>NIX_CFLAGS_COMPILE</envar>, and any <filename>lib</filename> and <filename>lib64</filename> subdirectories to <envar>NIX_LDFLAGS</envar>.
The setup hook itself contains some lengthy comments describing the exact convoluted mechanism by which this is accomplished.
Bintools Wrapper's setup hook causes any <filename>lib</filename> and <filename>lib64</filename> subdirectories to be added to <envar>NIX_LDFLAGS</envar>.
Since CC Wrapper and Bintools Wrapper use the same strategy, most of the Bintools Wrapper code is sparsely commented and refers to CC Wrapper.
But CC Wrapper's code, by contrast, has quite lengthy comments.
Bintools Wrapper merely cites those, rather than repeating them, to avoid falling out of sync.
</para>
<para>
A final task of the setup hook is defining a number of standard environment variables to tell build systems which executables full-fill which purpose.
They are defined to just be the base name of the tools, under the assumption that CC Wrapper's binaries will be on the path.
They are defined to just be the base name of the tools, under the assumption that Bintools Wrapper's binaries will be on the path.
Firstly, this helps poorly-written packages, e.g. ones that look for just <command>gcc</command> when <envar>CC</envar> isn't defined yet <command>clang</command> is to be used.
Secondly, this helps packages not get confused when cross-compiling, in which case multiple CC wrappers may be simultaneous in use (targeting different platforms).
<envar>BUILD_</envar>- and <envar>TARGET_</envar>-prefixed versions of the normal environment variable are defined for the additional CC Wrappers, properly disambiguating them.
Secondly, this helps packages not get confused when cross-compiling, in which case multiple Bintools Wrappers may simultaneously be in use.
<footnote><para>
Each wrapper targets a single platform, so if binaries for multiple platforms are needed, the underlying binaries must be wrapped multiple times.
As this is a property of the wrapper itself, the multiple wrappings are needed whether or not the same underlying binaries can target multiple platforms.

A problem with this final task is that Bintools Wrapper is honest and defines <envar>LD</envar> as <command>ld</command>.
Most packages, however, firstly use the C compiler for linking, secondly use <envar>LD</envar> anyways, defining it as the C compiler, and thirdly, only so define <envar>LD</envar> when it is undefined as a fallback.
This triple-threat means CC Wrapper will break those packages, as LD is already defined as the actually linker which the package won't override yet doesn't want to use.
This triple-threat means Bintools Wrapper will break those packages, as LD is already defined as the actual linker which the package won't override yet doesn't want to use.
The workaround is to define, just for the problematic package, <envar>LD</envar> as the C compiler.
A good way to do this would be <command>preConfigure = "LD=$CC"</command>.

CC Wrapper also like Bintools Wrapper defines standard environment variables with the names of the tools it wraps, for the same reasons described above.
Importantly, while it includes a <command>cc</command> symlink to the c compiler for portability, the <envar>CC</envar> will be defined using the compiler's "real name" (i.e. <command>gcc</command> or <command>clang</command>).
This helps lousy build systems that inspect on the name of the compiler rather than run it.
