Input source to compile. The following types are supported: |
|
|
|
- Strings relative to the current source directory |
|
- [[@file]] objects defined in any preceding build file |
|
- The return value of configure-time generators such as [[configure_file]] |
|
- The return value of build-time generators such as |
|
[[custom_target]] or [[generator.process]] |
|
|
|
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 [order-only |
|
dependency](https://ninja-build.org/manual.html#ref_dependencies) on |
|
all generated input files, including unknown files. This is needed to |
|
bootstrap the generation of the real dependencies in the |
|
[depfile](https://ninja-build.org/manual.html#ref_headers) 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. |

default: true |
|
since: 0.38.0 |
|
description: | |
|
Causes, when set to `true`, to have this target be built by default. |
|
This means it will be built when `meson compile` is called without any |
|
arguments. The default value is `true` for all built target types. |

|
link_args: |
|
type: list[str] |
|
description: | |
|
Flags to use during linking. You can use UNIX-style |
|
flags here for all platforms. |
|
|
|
link_depends: |
|
type: str | file | custom_tgt | custom_idx |
|
description: | |
|
Strings, files, or custom targets the link step depends on |
|
such as a symbol visibility map. The purpose is to |
|
automatically trigger a re-link (but not a re-compile) of the target |
|
when this file changes. |
|
|
|
link_language: |
|
type: str |
|
since: 0.51.0 |
|
description: | |
|
Makes the linker for this target be for the specified language. |
|
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. |
|
|
|
*(broken until 0.55.0)* |

|
|
link_whole: |
|
type: list[lib | custom_tgt | custom_idx] |
|
since: 0.40.0 |
|
description: | |
|
Links all contents of the given static libraries |
|
whether they are used by not, equivalent to the `-Wl,--whole-archive` argument flag of GCC. |
|
|
|
*(since 0.41.0)* If passed a list that list will be flattened. |
|
|
|
*(since 0.51.0)* This argument also accepts outputs produced by |
|
custom targets. The user must ensure that the output is a library in |
|
the correct format. |
|
|
|
link_with: |
|
type: list[lib | custom_tgt | custom_idx] |
|
description: | |
|
One or more shared or static libraries |
|
(built by this project) that this target should be linked with. *(since 0.41.0)* If passed a |
|
list this list will be flattened. *(since 0.51.0)* The arguments can also be custom targets. |
|
In this case Meson will assume that merely adding the output file in the linker command |
|
line is sufficient to make linking work. If this is not sufficient, |
|
then the build system writer must write all other steps manually. |

implicit_include_directories: |

install_dir: |
|
type: str |
|
description: | |
|
override install directory for this file. If the value is a relative path, |
|
it will be considered relative the `prefix` option. |
|
For example, if you want to install plugins into a subdir, you'd use |
|
something like this: `install_dir : get_option('libdir') / 'projectname-1.0'`. |
|
|
|
install_mode: |
|
type: list[str | int] |
|
since: 0.47.0 |
|
description: | |
|

|
and optionally the owner/uid and group/gid for the installed files. |
|
|
|
See the `install_mode` kwarg of [[install_data]] for more information. |
|
|
|
install_tag: |
|
type: str |
|
since: 0.60.0 |
|
description: | |
|
A string used by the `meson install --tags` command |
|
to install only a subset of the files. By default all build targets have the |
|
tag `runtime` except for static libraries that have the `devel` tag. |
|
|
|
install_rpath: |
|
type: str |
|
description: | |
|

type: list[extracted_obj] |
|
description: | |

|
name_prefix: |
|
type: str | list[void] |
|
description: | |
|
The string that will be used as the prefix for the |
|
target output filename by overriding the default (only used for |
|
libraries). By default this is `lib` on all platforms and compilers, |
|
except for MSVC shared libraries where it is omitted to follow |
|
convention, and Cygwin shared libraries where it is `cyg`. |
|
|
|
Set this to `[]`, or omit the keyword argument for the default behaviour. |
|
|
|
name_suffix: |
|
type: str | list[void] |
|
description: | |
|
The string that will be used as the extension for the |
|
target by overriding the default. By default on Windows this is |
|
`exe` for executables and on other platforms it is omitted. |
|
|
|
For shared libraries, the default value |
|
is `dylib` on macOS, `dll` on Windows, and `so` everywhere else. |
|
For static libraries, it is `a` everywhere. By convention MSVC |
|
static libraries use the `lib` suffix, but we use `a` to avoid a |
|
potential name clash with shared libraries which also generate |
|
import libraries with a `lib` suffix. |
|
|
|
Set this to `[]`, or omit the keyword argument for the default behaviour. |
|
|
|
override_options: |
|
type: list[str] |
|
since: 0.40.0 |
|
description: | |
|
takes an array of strings in the same format as `project`'s `default_options` |
|
overriding the values of these options |
|
for this target only. |
|
|
|
gnu_symbol_visibility: |
|
type: str |
|
since: 0.48.0 |
|
description: | |
|
Specifies how symbols should be exported, see |
|
e.g [the GCC Wiki](https://gcc.gnu.org/wiki/Visibility) for more |
|
information. This value can either be an empty string or one of |
|
`default`, `internal`, `hidden`, `protected` or `inlineshidden`, which |
|
is the same as `hidden` but also includes things like C++ implicit |
|
constructors as specified in the GCC manual. Ignored on compilers that |
|
do not support GNU visibility arguments. |

default: "'console'" |
|
since: 0.56.0 |
|
description: | |

|

|
mode programs and `windows` for gui apps. The value can also contain |
|
version specification such as `windows,6.0`. See [MSDN |
|
documentation](https://docs.microsoft.com/en-us/cpp/build/reference/subsystem-specify-subsystem) |
|

rust_crate_type: |
|
type: str |
|
since: 0.41.0 |
|
description: | |
|
Set the specific type of rust crate to compile (when compiling rust). |
|
|
|
If the target is an [[executable]] this defaults to "bin", the only |
|
allowed value. |
|
|
|
If it is a [[static_library]] it defaults to "lib", and may be "lib", |
|
"staticlib", or "rlib". If "lib" then Rustc will pick a default, "staticlib" |
|
means a C ABI library, "rlib" means a Rust ABI. |
|
|
|
If it is a [[shared_library]] it defaults to "lib", and may be "lib", |
|
"dylib", "cdylib", or "proc-macro". If "lib" then Rustc will pick a |
|
default, "cdylib" means a C ABI library, "dylib" means a Rust ABI, and |
|
"proc-macro" is a special rust proceedural macro crate. |
|
|
|
"proc-macro" is new in 0.62.0.
