The output_is_64bit, sizeof, cross_sizeof, compute_int and cross_compute_int
methods are reimplemented for Fortran compilers. Those inherited from
CLikeCompiler do not work since they assume C or C++.
Note that those tests rely on Fortran 2008 features (notably the c_sizeof
operator).
Closes#12757
In the case the main project has a .wrap file for a cargo subproject,
that subproject's Cargo.lock must be loaded before we can recursively
fetch all its dependencies.
The library name defaults to its package name, but it can be different.
For example:
- package name: cairo-sys-rs
- library name: cairo-sys
- dependency name: ffi
Introduce a global Cargo interpreter state that keeps track of enabled
features on each crate.
Before generating AST of a Cargo subproject, it downloads every
sub-subproject and resolves the set of features enabled on each of them
recursively. When it later generates AST for one its dependencies, its
set of features and dependencies is already determined.
This is functionally equivalent to the logic used to locate the cross
exe_wrapper, but puts it below the "Compilers" heading rather than
"Other binaries".

Recent versions of the architecture-properties package provide a
cross-exe-wrapper package containing
${DEB_HOST_GNU_TYPE}-cross-exe-wrapper, which is currently a wrapper
around qemu-user but could use different emulators on each architecture
if it becomes necessary in the future.

In Debian testing/unstable, there are wrappers available for various
GObject-Introspection tools during cross-builds, using qemu internally.

Cross-tools on Debian generally follow the naming convention set by
Autotools AC_CHECK_TOOL, where the name is prefixed with the GNU
architecture tuple for the host architecture. env2mfile was already
using this for pkg-config, but there are many other tools that can
be detected in the same way.

Remove trailing periods for consistency with other option descriptions, and use
a consistent description for `winlibs` options everywhere (the one in the
documentation).
`outfilelist` is the output list of the target, while `outfiles` is the output
list of the individual commands
Bug: mesonbuild/meson/pull/13304#issuecomment-2226398671
As the 2018 standard changes the way rust handles externs, and is the
first edition that allows `--extern crate=path` to completely replace
(in all but a few corner cases) the use of `extern crate` in the rust
files.
This setting is for things like `ccache`, but if Meson treats zig that
way, then it will expand the second argument to become:
```
/usr/bin/zig /usr/lib64/ccache/cc
```
in CMake and `/usr/lib64/ccache/cc` is _not_ an argument to `zig`.
If you run
```
$ CC='zig cc' CXX='zig c++' ./meson.py setup 'test cases/cmake/1 basic' build
```
then CMake will fail to compile a "simple test program" and setup
fails.
The first versions of Emscripten that correspond with the Clang version
Meson uses to determine flag support don't actually support the expected
flags. So I went through and picked the first version that actually
worked with the expected flags.
Fixes#13628
macOS mistakenly ships /usr/bin/ncurses5.4-config and a man page for
it, but none of the headers or libraries are available in the location
advertised by it. Ignore /usr/bin because it can only contain this
broken configtool script. Homebrew is /usr/local or /opt/homebrew.
Xcode's command-line tools SDK does include curses, but the configtool
in there is wrong too, and anyway we can't just randomly pick it up
since the user must explicitly select that as a target by using
a native file. The MacOSX SDK itself does not include curses.
We also can't ignore ncurses5.4-config entirely because it might be
available in a different prefix.
The D stdlib function std.process.spawnProcessPosix suffers from a bug
that causes any program that calls it to OOM if the nofile ulimit is
large.
This doesn't affect CI currently but trying to run or build the
containers locally will most likely crash when calling dub as docker
defaults to something like 1073741816 for both the hard limit and soft
limit. Lowering the soft limit is enough to make dub behave.

`DEB_HOST_ARCH` encodes both the CPU family and the OS, so using it to
get the CPU type gives the wrong answer for non-Linux ports.
However, `DEB_HOST_GNU_CPU` gives less detailed information about the
CPU: it's `arm` for all 32-bit ARM CPUs, and doesn't distinguish between
the differing baselines of `armel` (ARMv5 softfloat) and `armhf`
(ARMv7 hardfloat).
When cross-compiling for x86_64 Linux, this changes the `cpu()` from
`amd64` to `x86_64`, which is consistent with the answer we get during
native builds on that architecture.
When cross-compiling for `ppc64el`, this changes the `cpu()` from
`ppc64el` to `ppc64`, which is a reasonable change but is still not
consistent with what we see during native builds (which is `ppc64le`):
see #13741 for that.

All official Debian release architectures use the Linux kernel, but
unofficial ports like hurd-i386 and kfreebsd-amd64 use the Hurd and
FreeBSD kernel, respectively.
Map Linux to 'linux' and kFreeBSD ports to 'freebsd' as per the
reference tables in Meson's documentation. For now, use the Debian
system name such as 'hurd' for anything else (see #13740 for the
question of whether Hurd should identify its kernel differently).

This test parses several possible outputs of dpkg-architecture and
asserts that they produce the expected MachineInfo.
To avoid depending on suitable cross-tools being installed, use
unittest.mock to override locate_path with a version that pretends that
all of the tools we're interested in are in /usr/bin.
Similarly, use mock environment variables to exercise what happens
when we have those set.
The test data used here exercises most variations:
* big- and little-endianness
* GNU CPU (x86_64) differing from dpkg CPU (amd64)
* Linux, kFreeBSD and Hurd
* special-cased architectures: x86, arm, mips64el, ppc64el
expected_compilers() intentionally doesn't assume that every compiler
is gcc (even though they all are, right now), because #13721 proposes
adding valac which does not take a gcc suffix.

Separating the part that runs dpkg-architecture from the part that
interprets its results will make it easier to unit-test the latter.
