You can use stdenv.hostPlatform.emulator to get an executable that
runs cross-built binaries. This could be any emulator. For instance,
we use QEMU to emulate Linux targets and Wine to emulate Windows
targets. To work with qemu, we need to support custom targets.
I’ve reworked the cross tests in pkgs/test/cross to use this
functionality.
Also, I’ve used talloc to cross-execute with the emulator. There
appears to be a cross-execute for all waf builds. In the future, it
would be nice to set this for all waf builds.
Adds stdenv.hostPlatform.qemuArch attrbute to get the qemuArch for
each platform.

- respect libc’s incdir and libdir
- make non-unix systems single threaded
- set LIMITS_H_TEST to false for avr
- misc updates to support new libc’s
- use multilib with avr
For threads we want to use:
- posix on unix systems
- win32 on windows
- single on everything else
For avr:
- add library directories for avrlibc
- to disable relro and bind
- avr5 should have precedence over avr3 - otherwise gcc uses the wrong one
Documents functions in `lib.options` for docs generation with nixdoc.
The formatting change in the `mkOption` arguments is due to the way
`nixdoc` parses documentation comments on pattern arguments. It's not
ideal, but it works.
Documents functions in `lib.debug` for docs generation with nixdoc.
Note that type signatures and clearer descriptions are still missing
on some of these functions, but this is good enough for a first run.
Updates documentation comments with extra information for nixdoc[1]
compatibility.
Some documentation strings have additionally been reworded for
clarity.
"Faux types" are added where applicable, but some functions do things
that are not trivially representable in the type notation used so they
were ignored for this purpose.

This reverts commit 10addad603, reversing
changes made to 7786575c6c.
NixOS scripts should be kept in the NixOS source tree, not in
pkgs. Moving them around is just confusing and creates unnecessary
code/history churn.
The previous description "string" is misleading in the full options
manual pages; they are actually concatenated strings, with a specific
character.
The empty string version ("types.string") has been special-cased to
provide a better message.
The `overrideScope` bound by `makeScope` (via special `callPackage`)
took an override in the form `super: self { … }`. But this is
dangerously close to the `self: super { … }` form used by *everything*
else, even other definitions of `overrideScope`! Since that
implementation did not even share any code either until I changed it
recently in 3cf43547f4, this inconsistency
is almost certainly an oversight and not intentional.
Unfortunately, just as the inconstency is hard to debug if one just
assumes the conventional order, any sudden fix would break existing
overrides in the same hard-to-debug way. So instead of changing the
definition a new `overrideScope'` with the conventional order is added,
and old `overrideScope` deprecated with a warning saying to use
`overrideScope'` instead. That will hopefully get people to stop using
`overrideScope`, freeing our hand to change or remove it in the future.
This packags the Intel Math Kernel library on x86-64 platforms, which is a
dependency for many data science and machine learning packages.
Upstream, Intel provides proprietary binary RPMs with a permissive
redistribution license. These have been repackaged in both Debian and Anaconda,
so we are not the first distribution to redistribute.
The original build broke with the following linker issue:
```
CXXLD _PythonMagick.la
/nix/store/h0lbngpv6ln56hjj59i6l77vxq25flbz-binutils-2.30/bin/ld: cannot find -l-L/nix/store/4gh6ynzsd5ndx37hmkl62xa8z30k43y1-imagemagick-6.9.9-34/lib
collect2: error: ld returned 1 exit status
```
This happens since `BOOST_PYTHON_LIB` wasn't set properly, however
`_PythonMagick.la` was linked with `-l$(BOOST_PYTHON_LIB)
$(MAGICK_LIBS)`. With an empty `BOOST_PYTHON_LIB` the linker got
confused.
To work around this, the `boost` library directory needs to be specified
explicitly. To ensure that the changes take effect, the original
`configure` script shipped with `$src` needs to be removed and recreated
using the `autoreconfHook`.
Additionally the `imagemagick` license (https://spdx.org/licenses/ImageMagick.html)
needs to be added to `lib/licenses.nix` to document the proper license
of `pythonmagick` in the meta section.
This has been not touched in 6 years. Let's remove it to cause less
problems when adding new cross-compiling infrastructure.
This also simplify gcc significantly.
- moved function into strings.nix
- renamed function from makePerl5Lib
- removed duplicates entries in the resulting value
- rewrote the function from scratch after learning a few things (much cleaner now)
Another attempt after my sloppy 48ccdf322d.
@Infinisil, thanks again, reverted in 4794aa5de2 and explained my mistakes in 48ccdf322d (commitcomment-29678643). I start with their work and provide this proof of this commit's correctness:
```nix
(lib.fixedPoints.extends (lib.flip g) f) # now
((f: rattrs: self: let super = rattrs self; in super // f self super) (lib.flip g) f) # inline extends
(self: let super = f self; in super // (lib.flip g) self super) # beta reduce
(self: let super = f self; in super // g super self) # beta reduce
(self_: let super = f self_; in super // g super self_) # alpha rename
(self_: let super = f self_; in super // g super self_) # original, same
```
Eventually we might harmonize `overrideScope`'s `g` parameter with the general pattern, but I leave that breaking change as a separate step. Best not to refactor and break at once, and at least the abstractions make the oddity clearer.
$ nix repl lib
Welcome to Nix version 2.0.2. Type :? for help.
Loading 'lib'...
Added 350 variables.
-- this is the exact example from the function's documentation:
nix-repl> recursiveUpdateUntil (path: l: r: path == ["foo"]) {
# first attribute set
foo.bar = 1;
foo.baz = 2;
bar = 3;
} {
#second attribute set
foo.bar = 1;
foo.quz = 2;
baz = 4;
}
{ bar = 3; baz = 4; foo = { bar = 1; baz = 2; quz = 2; }; }
-- although the documentation says:
{
foo.bar = 1; # 'foo.*' from the second set
foo.quz = 2; #
bar = 3; # 'bar' from the first set
baz = 4; # 'baz' from the second set
}
binutils expects x86_64-unknown-netbsd<version> (only 3 parts!). Any other combo seems to fail.
Also handle darwin versions similarly.

* The ELK stack is upgraded to 6.3.2.
* `elasticsearch6`, `logstash6` and `kibana6` now come with X-Pack which is
a suite of additional features. These are however licensed under the unfree
"Elastic License".
* Fortunately they also provide OSS versions which are now packaged
under: `elasticsearch6-oss`, `logstash6-oss` and `kibana6-oss`.
Note that the naming of the attributes is consistent with upstream.
* The test `nix-build nixos/tests/elk.nix -A ELK-6` will test the OSS
version by default. You can also run the test on the unfree ELK using:
`NIXPKGS_ALLOW_UNFREE=1 nix-build nixos/tests/elk.nix -A ELK-6 --arg enableUnfree true`
Nix now supports floats & we can pretty easily map them to Plist’s
<real></real> type. Note that I am unsure how this affects older
version of Nix that may or may not have builtins.isFloat available.
Make sure this satisfies minver.nix’s "1.11" requirement.
Instead of using a string to describe kernel config, use a nix
attribute set, then converted to a string.
- allows to override the config, aka convert 'yes' into 'modules' or
vice-versa
- while for now merging different configs is still crude (last spec wins),
at least there should be only one CONFIG_XYZ value compared to the current string
config where the first defined would be used and others ignored.
[initial idea by copumpkin in 2016, a major rebase to 2018 by teto]
It wasn’t exactly clear which NDK you were using previously. This adds
an attribute to system that handles what version of the NDK we should
use when building things.

Before this change `mkRenamedOptionModule` would override option defaults
even when the old option name is left unused. For instance
```nix
{
optios = {
services.name.new = mkOption {
default = { one = {}; };
};
};
imports = [
(mkRenamedOptionModule [ "services" "name" "old" ] [ "services" "name" "new" "two" ])
];
config = {};
}
```
would evaluate to
`{ config.services.name.new = { two = {}; }; }`
when you'd expect it to evaluate to
`{ config.services.name.new = { one = {}; }; }`.
In particular, now the mainline kernel can be built on the RPi 1 as well
(so kernelBaseConfig should always be a mainline defconfig from now on).
And RPi 2 users can now use linux_rpi without doing the
`nixpkgs.config.platform = lib.systems.platforms.raspberrypi2;` dance.
toPath has confusing semantics and is never necessary; it can always
either just be omitted or replaced by pre-concatenating `/.`. It has
been marked as "!!! obsolete?" for more than 10 years in a C++
comment, hopefully removing it will let us properly deprecate and,
eventually, remove it.
