Note that this runs the script file that is in the _staging_ directory, not the one in the source directory. If the script file cannot be found in the staging directory, it is a hard error. The `MESON_DIST_ROOT` environment variables is set when dist scripts is run. *(since 0.54.0)* The `MESON_SOURCE_ROOT` and `MESON_BUILD_ROOT` environment variables are set when dist scripts are run. They are path to the root source and build directory of the main project, even when the script comes from a subproject. *(since 0.58.0)* This command can be invoked from a subproject, it was a hard error in earlier versions. Subproject dist scripts will only be executed when running `meson dist --include-subprojects`. `MESON_PROJECT_SOURCE_ROOT`, `MESON_PROJECT_BUILD_ROOT` and `MESON_PROJECT_DIST_ROOT` environment variables are set when dist scripts are run. They are identical to `MESON_SOURCE_ROOT`, `MESON_BUILD_ROOT` and `MESON_DIST_ROOT` for main project scripts, but for subproject scripts they have the path to the root of the subproject appended, usually `subprojects/`. *(since 1.4.0)* The `MESONREWRITE` environment variable contains the path to the rewrite 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 remove or replace any [[run_command]] that depends on the revision control system from the build configuration. Note that the value will contain many parts. For example, 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.

All positional arguments are passed as parameters. *(since 0.54.0)* If `meson install` is called with the `--quiet` option, the environment variable `MESON_INSTALL_QUIET` will be set. *(since 1.1.0)* If `meson install` is called with the `--dry-run` option, the environment variable `MESON_INSTALL_DRY_RUN` 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`.

This is useful for building modules that will be `dlopen()`ed and hence may contain undefined symbols that will be provided by the library that is loading it.

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:` [[build_target]] keyword argument can be used to create such a [[shared_library]] 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`.

Additionally, frameworks (OSX only) and [library-specific fallback detection logic](Dependencies.md#dependencies-with-custom-lookup-functionality) are also supported. *Since 0.60.0* more than one name can be provided, they will be tried in order and the first name to be found will be used. The fallback subproject will be used only if none of the names are found on the system. Once one of the name has been found, all other names are added into the cache so subsequent calls for any of those name will return the same value. This is useful in case a dependency could have different names, such as `png` and `libpng`. * Since *0.64.0* a dependency fallback can be provided by WrapDB. Simply download the database locally using `meson wrap update-db` command and Meson will automatically fallback to subprojects provided by WrapDB if the dependency is 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 [`subproject()`](#subproject) had been called. The subproject can be specified with the `fallback` argument. Alternatively, if the `fallback` argument is absent, *since 0.55.0* Meson can automatically identify a subproject as a fallback if a wrap file [provides](Wrap-dependency-system-manual.md#provide-section) 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 [Wrap documentation](Wrap-dependency-system-manual.md#provide-section) 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 that only looks in the specified subproject, and only if that's allowed by `--wrap-mode`. The returned object [[@dep]] also has additional methods. notes: - This function supports additional [library-specific](Dependencies.md#dependencies-with-custom-lookup-functionality) keyword arguments that may also be accepted (e.g. `modules` specifies submodules to use for dependencies such as Qt5 or Boost. `components` allows the user to manually add CMake `COMPONENTS` for the `find_package` lookup) varargs: name: names type: str since: 0.60.0 min_varargs: 1 description: | The names of the dependency to look up.

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 [[@exe]] object returned by [[executable]] or an [[@external_program]] object] returned by [[find_program]]. *(since 0.55.0)* 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 [`MALLOC_PERTURB_`](http://man7.org/linux/man-pages/man3/mallopt.3.html) 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: ```meson nomalloc = environment({'MALLOC_PERTURB_': '0'}) test(..., env: nomalloc, ...) ``` By default, the environment variables `ASAN_OPTIONS`, `UBSAN_OPTIONS`, and `MSAN_OPTIONS` are set to enable aborting on detected violations and to give a backtrace. To suppress this, `ASAN_OPTIONS`, `UBSAN_OPTIONS`, or `MSAN_OPTIONS` can be set in the environment. 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` *(since 0.62.0)* and, if supported by the external harness, `protocol: 'tap'` *(since 0.50.0)*. This will ensure that Meson logs each subtest as it runs, instead of including the whole log at the end of the run.

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 that build target.
