We mention --cross-file in the relevant page, but the fact that
--native-file is the command line argument to use is mentioned nowhere
other than a couple of release notes and the --help text for meson
setup.
This should be described in the docs.
This is generally a bad idea, e.g. it causes OSError on freebsd.
It also gets ignored by solaris and thus causes unittest failures.
The proper solution is to simply reject any attempt to set this, and log a
warning.
The install_emptydir function does apply the mode as well, and since it
is a directory it actually does something. This is the only place where
we don't reset the mode.
Although install_subdir also installs directories, and in theory it
could set the mode as well, that would be a new feature. Also it doesn't
provide much granularity and has mixed semantics with files. Better to
let people use install_emptydir + install_subdir.
Fixes#5902
`configure_file` is both an extremely complicated implementation, and
a strange place for copying. It's a bit of a historical artifact, since
the fs module didn't yet exist. It makes more sense to move this to the
fs module and deprecate this `configure_file` version.
This new version works at build time rather than configure time, which
has the disadvantage it can't be passed to `run_command`, but with the
advantage that changes to the input don't require a full reconfigure.
This is ambiguous, if the build directory has the same name as a
subcommand then we end up running the subcommand. It also means we have
a hard time adding *new* subcommands, because if it is a popular name of
a build directory then suddenly scripts that try to set up a build
directory end up running a subcommand instead.
The fact that we support this at all is a legacy design. Back in the
day, the "meson" program was for setting up a build directory and all
other tools were their own entry points, e.g. `mesontest` or
`mesonconf`. Then in commit fa278f351f we
migrated to the subcommand mechanism. So, for backwards compatibility,
we made those tools print a warning and then invoke `meson <tool>`. We
also made the `meson` tool default to setup.
However, we only warned for the other tools whose entry points were
eventually deleted. We never warned for setup itself, we just continued
to silently default to setup if no tool was provided.
`meson setup` has worked since 0.42, which is 5 years old this week.
It's available essentially everywhere. No one needs to use the old
backwards-compatible invocation method, but it continues to drag down
our ability to innovate. Let's finally do what we should have done a
long time ago, and sunset it.
It saves bandwidth and disk usage on downloaded subprojects, and people
very rarely need more than the single commit they’re using.
Add `depth=1` to the `[wrap-git]` examples in the rest of the
documentation, to make it more likely that people will copy-and-paste it
into their `.wrap` files.

We want to talk about the kwargs to the custom_target() function, but
tried to link to custom_tgt instead, which is not a function. It is an
object, but this was the wrong reference method for a type.
We want the function anyway, so use that.
The end of the paragraph indicates that the options which support --foo
will be listed in the help text. The beginning of the paragraph seems to
suggest the same thing, except it doesn't distinguish between -Dfoo and
--foo style options.
The first mention is redundant and feels like the wrong part of the
paragraph to mention it anyway.
With the previous commit, we made this smartly detect when parentheses
are not needed. But the example was broken, because it doesn't follow
its own documented rules to use `[[#` syntax. Add the missing hash
character.
The unit test was racy but surprisingly never failed on CI. The reason
is we need to ensure ninja build somelib.so before running `make` into
the external project.
Dlang uses both integer version "levels" and arbitrary string
identifiers, and we support both, but don't mention it in the docs.
Also update a test case to pass one via declare_dependency. We already
test this kwarg for build_target.
Leak sanitizer can be enabled without the whole AddressSanitizer, this
can be done by passing -fsanitize=leak as documented at [1].
Meson doesn't support this, so add support for it.

Logically, i18n.merge_file cannot ever take a MULTI_OUTPUT_KW, but it
does take a CT_OUTPUT_KW-like interface.
Actually trying to pass multiple merge_file outputs causes the
msgfmthelper script to be entirely malformed in the arguments it
accepts, and treat the broken one like a --flag, then exit with argparse
errors.
Even if we somehow assumed that somehow it was designed to actually
allow this, msgfmt doesn't support conceptually passing multiple outputs
so that would be a msgfmt error instead of an error inside the guts of
`meson --internal msgfmthelper`.
Same logic applies again for the itstool command and the itstool
internal helper.
Catch this error at configuration time by using the single-output kwarg
form.
Likewise, it's totally nonsense to accept multiple install_dir or
install_tags, and ever since commit 11f9638035
the CustomTarget itself won't even check this.
The `install_headers` function now has an optional argument
`preserve_path` that allows installing multi-directory
headerfile structures that live alongside sourcecode with a
single command.
For example, the headerfile structure
headers = [
'one.h',
'two.h',
'alpha/one.h',
'alpha/two.h',
'alpha/three.h'
'beta/one.h'
]
can now be passed to `install_headers(headers, subdir: 'mylib', preserve_path: true)`
and the resulting directory tree will look like
{prefix}
└── include
└── mylib
├── alpha
│ ├── one.h
│ ├── two.h
│ └── three.h
├── beta
│ └── one.h
├── one.h
└── two.h
Fixes#3371
python compiled extensions should never need to expose any symbol other
than PyInit_* which is declared with default visibility via
PyMODINIT_FUNC on supported compilers.
Thus, a reasonably sane default is to mark any other symbols as hidden,
while still respecting any manually specified visibility.
Gate this on the version of python itself, as not all versions decorate
PyMODINIT_FUNC properly.
Otherwise it always returns the value for c++98, starting with MSVC 2017
15.7 or later. Earlier versions are not affected by this mis-feature.
See: https://docs.microsoft.com/en-us/cpp/build/reference/zc-cplusplus?view=msvc-160
This was originally applied as 0b97d58548
but later reverted because it made the CI red. Try it again, now.

gcovr will read this file anyway, but if it exists we don't need to
assume that the project wishes to exclude subprojects/ -- they can
determine that themselves.
Fixes#3287Closes#9761
lcov doesn't read the config file by default, but we can do the smart
thing here.
Fixes#4628
By default, meson will try to look for shared libraries first before
static ones. In the meson.build itself, one can use the static keyword
to control if a static library will be tried first but there's no simple
way for an end user performing a build to switch back and forth at will.
Let's cover this usecase by adding an option that allows a user to
specify if they want dependency lookups to try static or shared
libraries first. The writer of the meson.build can manually specify the
static keyword where appropriate which will override the value of this
option.
This function can be used to add fundamental dependencies such as glib
to all build products in one fell swoop. This can be useful whenever,
due to a project's coding conventions, it is not really possible to
compile any source file without including the dependency.
