The only way to add it via warning_level is top opt in to -Wextra too.
But this is often not really desirable, since -Wextra is not stable --
it changes its meaning every compiler release, thus mysteriously adding
new warnings. Furthermore, it's not really the same kind of warning -- a
pedantic warning is always correct that your code is wrong, but defines
wrongness as "not per the portable standard". Unlike -Wextra it doesn't
try to judge your code to see if you're doing something that is "often
not what you meant", but is prone to false positives.
Really, we need different *kinds* of warning levels, possibly as an
array -- not just a monotonically increasing number. But since there's
currently nothing flexible enough to specify -Wpedantic without -Wextra,
we will just remove the warning for the former, and let people add it to
their project arguments in peace.
Since the current approach of demoting to the nearest C standard *might*
work, but might not. For projects like Glib that detect which standard
is used and fall back this is fine. For projects like libdrm that only
work with gnu standards, this wont. We're nog tusing a warning because
this shouldn't be fatal if --meson-fatal-warnings is used. Also demote a
similar message in IntelCl from warning to log.
And then update the choices in each leaf class. This way we don't end up
with another case where we implicitly allow an invalid standard to be
set on a compiler that doesn't have a 'std' setting currently.
As far as I can Tell, rust just handles this for us (it's always worked
with no special arguments from us). However, since we're going to add
support for base options for rust, we need to add the method.
When TemporaryDirectory() cleans up on __exit__ it sometimes throws
OSError noting that the dir isn't empty. This happens after the
first yield in this generator and leads to the exception being handled
which leads to a second yield.
contextlib.contextmanager() fails then since the function it wraps is only
allowed to yield once.
Fix this by not yielding again in the error case.
Fixes#7947
* Fix clang-tidy return value reporting
In case clang-tidy is invoked manually, i.e. if run-clang-tidy(.py) is
not found, Meson would not report the return value. This is caused by
ignoring the return value of manual_clangformat() in clangformat()
within mesonbuild/scripts/clangtidy.py.
Even though only more recent-versions of clang-tidy actually report an
non-zero exit code if errors are found, there is no reason Meson
shouldn't simply report any error codes it received from clang-tidy.
Fixes#7948.
* Rename methods in clangtidy.py from clangformat to clangtidy
For some unknown reason, the method names in clangtidy.py are clangformat()
and manual_clangformat(). This is confusing, as clang-format is not
invoked by them, clang-tidy is. Hence rename those from
{manual_}clangformat() → {manual_}clangtidy()
Using the std option, so now `rust_std=..` will work. I've chosen to use
"std" even though rust calls these "editions", as meson refers to
language versions as "standards", which makes meson feel more uniform,
and be less surprising.
Fixes: #5100
This fix a regression caused by
https://github.com/mesonbuild/meson/pull/7837, it wanted to make
InternalDependency's external_deps private but has side effect of making
StatisLibrary's external_deps private too.
It is technically correct to make them private, but Meson used to make
StaticLibrary deps public so they are usable without `pkg-config
--static` when we know there is only a static library available.
Fixes: #7929.
It's an easy mistake to do this:
gir1 = gnome.generate_gir(...)
gir2 = gnome.generate_gir(...
includes: ['GObject-2.0', gir1])
This fails with an error:
ERROR: Gir includes must be str, GirTarget, or list of them.
The issue is that the 'gir1[0]' should be passed instead of 'gir1'.
To make the problem slightly clearly, tweak the error message to be:
ERROR: Gir includes must be str, GirTarget, or list of them. Got TypelibTarget.
Right now sub-sub projects are not correctly registered, because we
don't have a way to pass up past the first level of subproject. This
patch changes that by making the build_Def_files as defined in the
Interpreter initializer accurate for translated dependencies, ie, cmake
dependencies won't define a dependency on a non-existent meson.build.
This means that it can always add the subi.build_def_files because they
are always accurate.
When finding the Qt compilation tools (moc, uic, rcc, lrelease), the
version strings contain a trailing newline character. This results in a
stray newline in the meson log:
Detecting Qt5 tools
Program /usr/lib64/qt5/bin/moc found: YES 5.14.2
(/usr/lib64/qt5/bin/moc)
Program /usr/lib64/qt5/bin/uic found: YES 5.14.2
(/usr/lib64/qt5/bin/uic)
Program /usr/lib64/qt5/bin/rcc found: YES 5.14.2
(/usr/lib64/qt5/bin/rcc)
Program /usr/lib64/qt5/bin/lrelease found: YES 5.14.2
(/usr/lib64/qt5/bin/lrelease)
Strip the version to avoid this, resulting in a cleaner log:
Detecting Qt5 tools
Program /usr/lib64/qt5/bin/moc found: YES 5.14.2 (/usr/lib64/qt5/bin/moc)
Program /usr/lib64/qt5/bin/uic found: YES 5.14.2 (/usr/lib64/qt5/bin/uic)

Subprojects that use the CMake PCH feature will cause
compilation/linker errors. The CMake PCH support
should thus be disabled until this can be properly
translated to meson.
There really isn't any reason to not always create missing
include directories inside the build dir. Just restricting
this to generate generated sources should work in an ideal
world, however, there exists lots of suboptimal CMake code
where this assumption is not always true.

Instead of trying to cover everything internally
This fixes glib-2.0-uninstalled.pc file.
GLib does `extra_cflags : ['-I${libdir}/glib-2.0/include']` because some
of its headers gets installed there. But when used uninstalled that path
makes no sense and pkg-config aborts because ${libdir} is not defined.
This cannot be worked around by GLib because Meson does not allow
setting different `extra_cflags` for -uninstalled.pc, and does not allow
setting libdir in `uninstalled_variables`.
The deprecation message for "gui_app" is appearing for every target
rather than just once, and even if the required version is older
than 0.56.0. Use @FeatureDeprecatedKwargs to fix both issues.
If static_library is used as a convenience library (e.g. for link_whole)
it should in principle not need position independent code.
However, if the executables that the libraries is linked to are PIE,
the non-PIC objects in the static library will cause linker errors.
To avoid this, obey b_pie for static libraries if either b_staticpic=false
or they use "pic: false".
Without this patch, QEMU cannot use b_staticpic, which causes a slowdown
on some QEMU benchmarks up to 20%.
When glib is a subproject we should use glib-compile-resources it
overrides using find_program() in the case it is not installed on the
build machine. With old glib version we have to run
glib-compile-resources at configure time to generate the list of
dependencies, but not when glib is recent enough.
