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(*langs*, native: false, required: *required*) and
|
||
|
|
add_languages(*langs*, native: true, required: false)`. This default behaviour
|
||
|
|
may change to `native: false` in a future Meson version.
|
||
|
|
|
||
|
|
example: |
|
||
|
|
```meson
|
||
|
|
project('foobar', 'c')
|
||
|
|
|
||
|
|
if compiling_for_osx
|
||
|
|
add_languages('objc')
|
||
|
|
endif
|
||
|
|
if add_languages('cpp', required : false)
|
||
|
|
executable('cpp-app', 'main.cpp')
|
||
|
|
endif

If set to `true`, Meson will halt if any of the languages
|
||
|
|
specified are not found. *(since 0.47.0)* The value of a
|
||
|
|
[`feature`](Build-options.md#features) option can also be passed.

If set to `true`, the language will be used to compile for the build
|
||
|
|
machine, if `false`, for the host machine.
