We should simply remap these to elide the ../ as it's pretty obviously
the natural expectation of using ../ to fetch files from outside the
project and then drop them *into* the project.
Monorepos will likely have a single license file (or set) under which
the monorepo is licensed. But there will be many components, each of
which may use a different build system, which are "standalone" for the
most part. We already support this case as long as you build from the
monorepo, but the resulting license file gets installed to
```
{licensedir}/../
```
which is silly and unhelpful.

When supplying -Wno-vla-larger-than to compiler.get_supported_arguments,
meson will inject -Wvla-larger-than as an argument which considered
invalid by GCC, as the converse argument is -Wvla-larger-than=<value>.
Just like CLikeCompiler._has_multi_arguments special-cases
-Wno-attributes=, do the same for -Wno-vla-larger-than.

Add an exception to the disabler check to allow objects with a `get_variable`
method to not always pick a disabler if their arguments contain one. This
mimics the behaviour already in place for calls to function, which has a set
of excepted functions.

#13837 broke both_lib transitive deps, because the
`as_static` and `as_shared` functions return libraries
that still contain references to the other lib type.

Both recvmmsg/sendmmsg and statx require the `_GNU_SOURCE` symbol to be
defined to be shown in headers, but statx has the additional property of
being defined on all glibc systems[1], unlike recvmmsg which isn't
implemented on Hurd[2][3].
With this fix, all tests now pass on Hurd.

Otherwise internal dependencies have auto-generated names that are not
human readable. Instead, use the name that the dependency overrides. For
example:
```meson
meson.override_dependency('zlib', declare_dependency())
dep_zlib = dependency('zlib')
assert(dep_zlib.name() == 'zlib')
```

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.

Test '230 external project' uses make, but is too dumb to use the
platform conventions for shared library names in installed files
expected by shared_lib, so special case that.

For other reasons, Meson transforms "-Wno-x" into "-Wx -Wno-x" for GCC,
but this breaks with "-Wno-attributes=x" with:
```
cc1plus: error: arguments ignored for '-Wattributes='; use '-Wno-attributes=' instead
```
Suppress that workaround for -Wno-attributes=.

Revert "interpreter: when overriding a dependency make its name match"
This reverts commit b1340e9bb1f243e4de8f2d89415a45ade476a3dc.
Revert "dependency: define equality and hash operators for Dependency"
This reverts commit 6d713e40f81512eadb0cc4654408d90cb22ba774.
This caused some projects to fail to build, such as libplacebo and
libepoxy. Taking libplacebo as the example, the produced build.ninja
does not include libvulkan.so as a linker input for
src/libplacebo.so.338.
We are probably getting dependency hashing wrong somewhere. Unsure where
exactly and unsure how to create a test case. We are also deep into rc2.
Revert it for now and try to re-land these changes for 1.6.

Regression test for #13372
|
|
This reverts commit 9f02d0a3e5a5ffc82256391c244b1af38e41ef78.
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

Which requires injecting some extra paths and the `-Xpreprocess` flag,
as well as extra search paths for libomp and the headers.

* Ensure private directory exists for custom targets
Some custom target commands will expect the `@PRIVATE_DIR@` to already exist, such as with `make -C @PRIVATE_DIR@ ...`
* Prefer `exist_ok` over catching exception

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.

When configuring a 'meson' or 'cmake@' style file,
add a case for escaped variables using matched pairs of
`\@` i.e. `\@foo\@ -> @foo@`.
The match for @var@ has been amended with a negative lookbehind
to ensure that any occurrances of `\@foo@` are not evaluated to
`\bar`.
The previous behaviour, matching `\@` and escaping only that character,
had undesirable side effects including mangling valid perl when
configuring files.

Only Environment and ConfigurationData are mutable. However, only
ConfigurationData becomes immutable after first use which is
inconsistent.
This deprecates modification after first use of Environment object and
clarify documentation.

That holds for all of these meson function: run_target, generator and

musl 1.2.5 exposes this symbol in the default profile, and in future
will expose it unconditionally, as it is on track to becoming part of
POSIX.
So rather than maintaining a list of systems to run this on, let's
just skip testing the feature test macro if we find ppoll in the
default profile.
