Add programming languages used by the project.
|
|
|
|
This is equivalent to having
|
|
them in the `project` declaration. This function is usually used to
|
|
add languages that are only used under some conditions.
|
|
|
|
Returns `true` if all languages specified were found and `false` otherwise.
|
|
|
|
If `native` is omitted, the languages may be used for either build or host
|
|
machine, but are never required for the build machine. (i.e. it is equivalent
|
|
to `add_languages(\fBlangs\fR, native: false, required: \fBrequired\fR) and
|
|
add_languages(\fBlangs\fR, native: true, required: false)`. This default behaviour
|

may change to `native: false` in a future Meson version.

libraries (`.so`, `.dll`, etc) will be linked.

These input files can be sources, objects, libraries, or any other
|
|
file. Meson will automatically categorize them based on the extension
|

and use them accordingly. For instance, sources (`.c`, `.cpp`,
|
|
`.vala`, `.rs`, etc) will be compiled and objects (`.o`, `.obj`) and
|
|
libraries (`.so`, `.dll`, etc) will be linked.
|
|
|
|
With the Ninja backend, Meson will create a build-time \fIorder-only
|
|
dependency\fR[3] on
|
|
all generated input files, including unknown files. This is needed to
|
|
bootstrap the generation of the real dependencies in the

|
\fIdepfile\fR[4] generated
|
|
by your compiler to determine when to rebuild sources. Ninja relies on
|
|
this dependency file for all input files, generated and non-generated.
|

The behavior is similar for other backends.

\fB Since \fR0.64.0* a dependency fallback can be provided by WrapDB. Simply download

|
|
not found on the system and the project does not ship their own `.wrap` file.
|
|
|
|
Dependencies can also be resolved in two other ways:
|
|
|
|
* if the same name was used in a `meson.override_dependency` prior to the call to `dependency`, the overriding dependency will be returned unconditionally; that is, the overriding dependency will be used independent of whether an external dependency is installed in the system. Typically, `meson.override_dependency` will have been used by a subproject.
|
|
|
|
* by a fallback subproject which, if needed, will be brought into the current build specification as if \fI`subproject()`\fR had been called. The subproject can be specified with the `fallback` argument. Alternatively, if the `fallback` argument is absent, \fBsince 0.55.0\fR Meson can automatically identify a subproject as a fallback if a wrap file \fIprovides\fR[14] the dependency, or if a subproject has the same name as the dependency. In the latter case, the subproject must use `meson.override_dependency` to specify the replacement, or Meson will report a hard error. See the \fIWrap documentation\fR[13] for more details. This automatic search can be controlled using the `allow_fallback` keyword argument.
|
|
|
|
If `dependency_name` is `''`, the dependency is always not found. So
|
|
with `required: false`, this always returns a dependency object for
|
|
which the `found()` method returns `false`, and which can be passed
|
|
like any other dependency to the `dependencies:` keyword argument of a
|
|
`build_target`. This can be used to implement a dependency which is
|
|
sometimes not required e.g. in some branches of a conditional, or with
|
|
a `fallback:` kwarg, can be used to declare an optional dependency

Manually specifies a subproject fallback

This is useful if the automatic search is not applicable or if you

|
|
subproject that contains a dependency object such as the return

value of \fIdeclare_dependency\fR or

\fIdependency\fR, etc. Note that this means the

fallback dependency may be a not-found dependency, in which

case the value of the `required:` kwarg will be obeyed.

`meson.override_dependency('dependency_name', subproj_dep)`

1. Program overrides set via \fImeson.override_find_program\fR

1. \fI`[provide]` sections\fR[13]

1. Project's source tree relative to the current subdir

The template strings passed to all the keyword arguments accept

the following special substitutions:

- `@BASENAME@`: the base of the input filename, e.g.: `foo.c.y` becomes `foo.c` (extension is removed)
|

|
Each string passed to the `output` keyword argument \fBmust\fR be
|
|
constructed using one or both of these two substitutions.
|
|
|
|
In addition to the above substitutions, the `arguments` keyword
|

argument also accepts the following:

|
|
- `@OUTPUT@`: the full path to the output file
|
|
.br

Obtains the value of the \fIproject build option\fR[18]

specified in the positional argument.
|
|
|
|
Note that the value returned for built-in options that end in `dir`
|
|
such as `bindir` and `libdir` is usually a path relative to (and
|
|
inside) the `prefix` but you should not rely on that, as it can also
|
|
be an absolute path \fIin some cases\fR[19].
|
|
\fI`install_dir` arguments\fR[20] handle that as expected
|
|
but if you need an absolute path, e.g. to use in a define etc.,
|
|
you should use the path concatenation operator like this:
|
|
`get_option('prefix') / get_option('localstatedir')`.
|
|
Never manually join paths as if they were strings.
|
|
|
|
For options of type `feature` a
|
|
\fIfeature\fR option object
|
|
is returned instead of a string.
|
|
See \fI`feature` options\fR[0]

This function can be used to dynamically obtain a variable. `res =

get_variable(varname, fallback)` takes the value of `varname` (which

must be a string) and stores the variable of that name into `res`. If

the variable does not exist, the variable `fallback` is stored to

`res`instead. If a fallback is not specified, then attempting to read

Input source to compile. The following types are supported:

.br

- The return value of build-time generators such as \fIcustom_target\fR or \fIgenerator.process\fR
|
|
|
|
These input files can be sources, objects, libraries, or any other
|
|
file. Meson will automatically categorize them based on the extension
|
|
and use them accordingly. For instance, sources (`.c`, `.cpp`,
|
|
`.vala`, `.rs`, etc) will be compiled and objects (`.o`, `.obj`) and
|
|
libraries (`.so`, `.dll`, etc) will be linked.
|
|
|
|
With the Ninja backend, Meson will create a build-time \fIorder-only
|
|
dependency\fR[3] on
|
|
all generated input files, including unknown files. This is needed to
|
|
bootstrap the generation of the real dependencies in the
|
|
\fIdepfile\fR[4] generated
|
|
by your compiler to determine when to rebuild sources. Ninja relies on
|
|
this dependency file for all input files, generated and non-generated.
|
|
The behavior is similar for other backends.

It is generally unnecessary to set

|
this, as Meson will detect the right linker to use in most cases. There are
|
|
only two cases where this is needed. One, your main function in an

executable is not in the language Meson picked, or second you want to force

a library to use only one ABI.

These input files can be sources, objects, libraries, or any other

file. Meson will automatically categorize them based on the extension

`.vala`, `.rs`, etc) will be compiled and objects (`.o`, `.obj`) and

|
libraries (`.so`, `.dll`, etc) will be linked.
|

With the Ninja backend, Meson will create a build-time \fIorder-only

|
all generated input files, including unknown files. This is needed to

|
bootstrap the generation of the real dependencies in the

|
|
by your compiler to determine when to rebuild sources. Ninja relies on

this dependency file for all input files, generated and non-generated.

The behavior is similar for other backends.

For backwards compatibility reasons you can also pass an array of

These input files can be sources, objects, libraries, or any other

`.vala`, `.rs`, etc) will be compiled and objects (`.o`, `.obj`) and

libraries (`.so`, `.dll`, etc) will be linked.

With the Ninja backend, Meson will create a build-time \fIorder-only

all generated input files, including unknown files. This is needed to

bootstrap the generation of the real dependencies in the

this dependency file for all input files, generated and non-generated.

These input files can be sources, objects, libraries, or any other

|
file. Meson will automatically categorize them based on the extension

`.vala`, `.rs`, etc) will be compiled and objects (`.o`, `.obj`) and

|
libraries (`.so`, `.dll`, etc) will be linked.
|
|

With the Ninja backend, Meson will create a build-time \fIorder-only

all generated input files, including unknown files. This is needed to

|
bootstrap the generation of the real dependencies in the

\fIdepfile\fR[4] generated

this dependency file for all input files, generated and non-generated.

*Linking to a shared module on platforms other than Android is deprecated, and will be an error
|
|
in the future*.
|
|
It was previously allowed because it was the only way to have a shared-library-like target that
|
|
contained references to undefined symbols. However, since 0.40.0, the `override_options:`
|
|
\fIbuild_target\fR keyword argument can be used to create such a \fIshared_library\fR by passing
|
|
`override_options: 'b_lundef=false'`. Shared modules have other characteristics that make
|
|
them incompatible with linking, such as a lack of SONAME.
|
|
On macOS and iOS, linking to shared modules is disallowed by the linker, so we disallow it at
|
|
configure time.
|
|
On Android, if a shared module `foo` uses symbols from another shared module `bar`, `foo` must
|
|
also be linked to `bar`. Hence, linking one shared module to another will always be allowed when
|
|
building for Android.

Input source to compile. The following types are supported:

|
|
|
|
These input files can be sources, objects, libraries, or any other
|
|
file. Meson will automatically categorize them based on the extension

|
and use them accordingly. For instance, sources (`.c`, `.cpp`,
|
|
`.vala`, `.rs`, etc) will be compiled and objects (`.o`, `.obj`) and
|
|
libraries (`.so`, `.dll`, etc) will be linked.
|
|
|
|
With the Ninja backend, Meson will create a build-time \fIorder-only
|
|
dependency\fR[3] on
|
|
all generated input files, including unknown files. This is needed to
|
|
bootstrap the generation of the real dependencies in the

|
\fIdepfile\fR[4] generated
|
|
by your compiler to determine when to rebuild sources. Ninja relies on
|
|
this dependency file for all input files, generated and non-generated.

The behavior is similar for other backends.

Takes the project specified in the positional argument and brings that

Subprojects must always be placed inside

the `subprojects` directory at the top source directory. So for

example a subproject called `foo` must be located in

Note that you can use the returned \fIsubproject\fR object

|

This function is used to summarize build configuration at the end of the build
|
|
process. This function provides a way for projects (and subprojects) to report
|
|
this information in a clear way.
|
|
|
|
The content is a series of key/value pairs grouped into sections. If
|
|
the section keyword argument is omitted, those key/value pairs are
|
|
implicitly grouped into a section with no title. key/value pairs can
|
|
optionally be grouped into a dictionary, but keep in mind that
|
|
dictionaries do not guarantee ordering. `key` must be string,
|
|
`value` can be:
|
|
|
|
- an integer, boolean or string
|
|
.br
|
|
- \fBsince 0.57.0\fR an external program or a dependency
|
|
.br
|
|
- \fBsince 0.58.0\fR a feature option
|
|
.br
|
|
- a list of those.
|
|
|
|
Instead of calling summary as `summary(key, value)`, it is also possible to
|
|
directly pass a dictionary to the \fIsummary\fR function, as seen in the example
|
|
below.
|
|
|
|
`summary()` can be called multiple times as long as the same
|
|
section/key pair doesn't appear twice. All sections will be collected
|
|
and printed at the end of the configuration in the same order as they
|
|
have been called.

Defines a test to run with the test harness. Takes two positional
|

arguments, the first is the name of the test and the second is the

executable to run. The executable can be an \fIexe\fR object returned by
|
|
\fIexecutable\fR or an \fIexternal_program\fR object] returned by
|
|
\fIfind_program\fR.
|
|
|
|
\fB(since 0.55.0)\fR When cross compiling, if an exe_wrapper is needed and
|
|
defined the environment variable `MESON_EXE_WRAPPER` will be set to
|
|
the string value of that wrapper (implementation detail: using
|
|
`mesonlib.join_args`). Test scripts may use this to run cross built
|
|
binaries. If your test needs `MESON_EXE_WRAPPER` in cross build
|
|
situations it is your responsibility to return code 77 to tell the
|
|
harness to report "skip".
|
|
|
|
By default, environment variable
|
|
\fI`MALLOC_PERTURB_`\fR[26]
|
|
is automatically set by `meson test` to a random value between 1..255.
|
|
This can help find memory leaks on configurations using glibc,
|
|
including with non-GCC compilers. However, this can have a performance
|
|
impact, and may fail a test due to external libraries whose internals
|
|
are out of the user's control. To check if this feature is causing an
|
|
expected runtime crash, disable the feature by temporarily setting
|
|
environment variable `MALLOC_PERTURB_=0`. While it's preferable to
|
|
only temporarily disable this check, if a project requires permanent
|
|
disabling of this check in meson.build do like:

In addition to running individual executables as test cases, `test()`

can also be used to invoke an external test harness. In this case,

it is best to use `verbose: true` \fB(since 0.62.0)\fR and, if supported
|
|
by the external harness, `protocol: 'tap'` \fB(since 0.50.0)\fR. This will

the whole log at the end of the run.

This command detects revision control commit information at build time

|

Meson will read the contents of `input`, substitute the
|
|
`replace_string` with the detected revision number, and write the
|
|
result to `output`. This method returns a
|
|
\fIcustom_tgt\fR object that (as usual) should be

For example, if you generate a header with this and want to use that
|
|
in a build target, you must add the return value to the sources of

Input source to compile. The following types are supported:
|
|
|
|
- Strings relative to the current source directory
|
|
.br
|
|
- \fIfile\fR objects defined in any preceding build file
|
|
.br
|
|
- The return value of configure-time generators such as \fIconfigure_file\fR
|
|
.br
|
|
- The return value of build-time generators such as \fIcustom_target\fR or \fIgenerator.process\fR
|
|
|
|
These input files can be sources, objects, libraries, or any other
|
|
file. Meson will automatically categorize them based on the extension
|
|
and use them accordingly. For instance, sources (`.c`, `.cpp`,
|
|
`.vala`, `.rs`, etc) will be compiled and objects (`.o`, `.obj`) and
|
|
libraries (`.so`, `.dll`, etc) will be linked.
|
|
|
|
With the Ninja backend, Meson will create a build-time \fIorder-only
|
|
dependency\fR[3] on
|
|
all generated input files, including unknown files. This is needed to
|
|
bootstrap the generation of the real dependencies in the
|
|
\fIdepfile\fR[4] generated
|
|
by your compiler to determine when to rebuild sources. Ninja relies on
|
|
this dependency file for all input files, generated and non-generated.
|
|
The behavior is similar for other backends.

Causes the script given as an argument to be run during the install step,

|
this script will have the environment variables `MESON_SOURCE_ROOT`,
|

`MESON_BUILD_ROOT`, `MESON_INSTALL_PREFIX`,
|
|
`MESON_INSTALL_DESTDIR_PREFIX`, and `MESONINTROSPECT` set.

\fB(since 0.54.0)\fR If `meson install` is called with the `--quiet` option, the

environment variable `MESON_INSTALL_QUIET` will be set.
|
|
|
|
Meson uses the `DESTDIR` environment variable as set by the
|
|
inherited environment to determine the (temporary) installation
|
|
location for files. Your install script must be aware of this while
|
|
manipulating and installing files. The correct way to handle this is
|
|
with the `MESON_INSTALL_DESTDIR_PREFIX` variable which is always set
|
|
and contains `DESTDIR` (if set) and `prefix` joined together. This
|
|
is useful because both are usually absolute paths and there are
|
|
platform-specific edge-cases in joining two absolute paths.
|
|
|
|
In case it is needed, `MESON_INSTALL_PREFIX` is also always set and
|
|
has the value of the `prefix` option passed to Meson.
|
|
|
|
`MESONINTROSPECT` contains the path to the introspect command that
|
|
corresponds to the `meson` executable that was used to configure the
|
|
build. (This might be a different path than the first executable
|
|
found in `PATH`.) It can be used to query build configuration. Note
|
|
that the value will contain many parts, f.ex., it may be `python3
|
|
/path/to/meson.py introspect`. The user is responsible for splitting
|
|
the string to an array if needed by splitting lexically like a UNIX
|
|
shell would. If your script uses Python, `shlex.split()` is the
|
|
easiest correct way to do this.

These compiler checks do not use compiler arguments added
|
|
with `add_*_arguments()`, via `-Dlang_args` on the command-line, or
|
|
through `CFLAGS`/`LDFLAGS`, etc in the environment. Hence, you can
|
|
trust that the tests will be fully self-contained, and won't fail
|
|
because of custom flags added by other parts of the build file or by
|
|
users.
|
|
Note that if you have a single prefix with all your dependencies, you
|
|
might find it easier to append to the environment variables
|
|
`C_INCLUDE_PATH` with GCC/Clang and `INCLUDE` with MSVC to expand the
|
|
default include path, and `LIBRARY_PATH` with GCC/Clang and `LIB` with
|
|
MSVC to expand the default library search path.
|
|
|
|
However, with GCC, these variables will be ignored when
|
|
cross-compiling. In that case you need to use a specs file. See:
