This reverts commit aee941559c.
The commit being reverted breaks compilation of a major Meson consumer
(Mesa). As a result, various distros are either pinning to <1.4.0 (before
the commit) or performing this same revert downstream.
Fixing a regression takes priority, so let's revert.
Fixes: https://github.com/mesonbuild/meson/issues/12973
Emscripten version numbers are unrelated to Clang version numbers,
so it is necessary to change the version checks for `c_std=c17` & co.
Without that, no project that defaults to C17 or newer will build with
Emscripten.
See https://github.com/pyodide/pyodide/discussions/4762 for more
context. Also note that this bug caused defaulting to C17 in
scikit-learn to be reverted (scikit-learn#29015), and it may be a
problem for SciPy 1.14.0 too since that release will upgrade from C99
to C17.

Using the keyword argument dependencies with compiler.links() for vala doesn't work as the library being linked to needs to be prefixed with --pkg= before being passed to valac.
This uses objfw-config to get to the flags, however, there's still
several todos that can only be addressed once dependencies can have
per-language flags.
GCC only has very limited support for Objective-C and doesn't support
any of the modern features, so whenever Clang is available, it should be
used instead. Essentially, the only reason to ever use GCC for
Objective-C is that Clang simply does not support the target system.
Fedora has switched to zlib-ng, which has a version of `1.3.0.zlib-ng`,
causing AllPlatformTests.test_summary to fail. dl is much less likely to
change format.
We have two copies of other.h, one of which is generated. If we don't
include the include/ directory then building fails unless the
custom_target which copies it over, happens to run early enough. On
parallel builds this may fall on its face.
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.
Some tests for `gnome.mkenums_simple` were only compiled, but not run.
Most bugs will be caught by compilation alone, but it's better to run
the generated binary too in case there are runtime issues in the
generated code.
The naming of all enum tests is now unified as well.
They were skipped with llvm 17 based on the version, and they are
now no longer skipped with v18 and also pass now.
This depends on #12964 for llvm 18 support in meson.
The test.json format currently has three keys related to skipping tests:
* `skip_on_jobname`
* `skip_on_os`
* `skip_on_env`
While `skip_on_env` marks the test itself as skipped, i.e. they don't get run when the
conditions are met, the other two skip options are just marking the test as "expected to be skipped"
if the conditions apply, i.e. they want to see `MESON_SKIP_TEST` in the output and things will
fail if that doesn't happen. They don't actually skip the tests as the names imply.
To make this clearer rename the keys:
* `skip_on_jobname` -> `expect_skip_on_jobname`
* `skip_on_os` -> `expect_skip_on_os`
`skip_on_env` stays the same, since that actually skips.
The docs were also confused about this, so adjust that too.
By adding the option name to UserOption object, it is now possible to
display the name of the affected option when the given option value is
not valid.
Fixes#12635
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')
```
Fixes: #12967
When linking with a Rust rlib, we should also link with its external
system dependencies. This was currently done only for C ABI crates, do
it for both rlib and staticlib now.
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.
When the proc-macro rlib is in a different subdir, it would miss the
needed -L argument and rustc would not find it. Meson was assuming that
proc-macros are only needed when building libraries that uses it, but it
turns out that was wrong, as show by the unit test.
Cargo implements this configuration option to override the entry point
of the library.
To get test coverage, I've modified one of the two Cargo subprojects
in the test to use a non-default library entrypoint. The other still
uses the default.
