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.
Previously, the documentation said that the CPU name might be amd64,
but in fact x86_64 (AMD64) machines are detected as x86_64 in both
cpu() and cpu_family() during native builds. Reference:
https://buildd.debian.org/status/fetch.php?pkg=libglvnd&arch=amd64&ver=1.7.0-1%2Bb1&stamp=1714222481&raw=0
Instead, mention the only common case for more-specific CPU names
other than 32-bit x86, namely 32-bit ARM. On Debian's autobuilders
(which are running 32-bit user-space on a 64-bit-capable CPU),
native builds genuinely do present as `armv8l`:
https://buildd.debian.org/status/fetch.php?pkg=libglvnd&arch=armhf&ver=1.7.0-1%2Bb1&stamp=1714223924&raw=0
On other machines, they might be some older CPU functionality level.
At the time of writing, cpu() *can* return amd64 when using
`meson env2mfile` on Debian systems, but I think that's a bug in
env2mfile (#13742).

For many years now, meson hasn't required manually entering a Visual
Studio command prompt but has autodetected it. This confuses some
readers of this outdated documentation into thinking it is much harder
than it is.
This allows checking for tools that may not be available in older version of qt
or avoiding requesting tools that may not be necessary for a given project

These errors can make reading comments and documentation
unnecessarily confusing for users and contributors who
do not speak English as their first language.
This commit harmonizes the handling of `d_import_dirs` and
`include_directories`. The treatment of `d_import_dirs` was also
different depending on the context: in `declare_dependency` it was
treated like the `include_directories`, but in `build_target` et al,
it had special treatment. With this commit, they are all treated
by the same function. The documentation has been updated to
reflect this.
Fixes#12742
There are two environments on Windows:
* When invoked in a Cygwin or MSYS2 MSYS shell, `host_machine.system()` returns `cygwin`.
* When invoked in a MSYS2 MINGW32/MINGW64/UCRT64/CLANG64/etc., `host_machine.system()` returns `windows`.
When projects do not specify a minimum meson version, we used to avoid
giving them the benefit of the Feature checks framework. Instead:
- warn for features that were added after the most recent semver bump,
since they aren't portable to the range of versions people might use
these days
- warn for features that were deprecated before the upcoming semver
bump, i.e. all deprecated features, since they aren't portable to
upcoming semver-compatible versions people might be imminently upgrading
to
Previously, setting `MESON_TESTTHREADS` to a number lower than 1
resulted in unexpected behavior. This commit introduces test for
negative value (with fallback to 1), and fallback to core count in case
it is set to 0.
It improves experience in job-matrix type of CI workflows, where some
jobs within the matrix require single job execution, whereas others can
default to taking core count as the job count.

Although it's not especially common, there are certainly cases where it's
useful to pass the path to an external program to a test program.

CMake has two target properties, LINK_OPTIONS and INTERFACE_LINK_OPTIONS.
The former is for link flags that apply only to the target (PRIVATE).
The latter is used for link flags that propagate to dependents (PUBLIC
or INTERFACE). Meson currently propagates all flags, PUBLIC and PRIVATE,
as part of the generated dependency() which causes problems when some of
the private flags are highly disruptive, e.g. `-Wl,--version-script`.
Tease apart the two kinds of link flags and, for non-static libraries,
only propagate the PUBLIC/INTERFACE flags and not the PRIVATE ones.
This reverts commit 9f02d0a3e5.
It turns out that this does introduce a behavioral change in existing
users of ConfigurationData, which it wasn't supposed to (it was supposed
to preserve behavior there, and add a new *warning* for
EnvironmentVariables).
This breaks projects such as pulseaudio, libvirt, and probably more.
Roll back the change and try again after 1.5.0 is released.
Fixes: #13372
When trying to get the version of a program, meson was previously
hardcoded to run the binary with `--version`. This does work with the
vast majority of programs, but there are a few outliers (e.g. ffmpeg)
which have an unusual argument for printing out the version. Support
these programs by introducing a version_argument kwarg in find_program
which allows users to override `--version` with whatever the custom
argument for printing the version may be for the program.
Cargo.lock is essentially identical to subprojects/*.wrap files. When a
(sub)project has a Cargo.lock file this allows automatic fallback for
its cargo dependencies.
New people that want to use Meson for building Python extensions most
probably will read Python module docs first. Direct them to meson-python
and suggest to set `python.install_env=auto`.
