## Script environment variables

|
|
|
||
|
|
| Value | Comment |
|
||
|
|
| ----- | ------- |
|
||
|
|
| MESONINTROSPECT | Command to run to run the introspection command, may be of the form `python /path/to/meson introspect`, user is responsible for splitting the path if necessary. |
|
||
|
|
| MESON_BUILD_ROOT | Absolute path to the build dir |
|
||
|
|
| MESON_DIST_ROOT | Points to the root of the staging directory, only set when running `dist` scripts |
|
||
|
|
| MESON_SOURCE_ROOT | Absolute path to the source dir |
|
||
|
|
| MESON_SUBDIR | Current subdirectory, only set for `run_command` |
|
||
|
|
|
||
|
|
## CPU families
|
||
|
|
|
||
|
|
These are returned by the `cpu_family` method of `build_machine`,
|
||
|
|
`host_machine` and `target_machine`. For cross compilation they are
|
||
|
|
set in the cross file.

Any cpu family not listed in the above list is not guaranteed to

|
|
remain stable in future releases.
|
||
|
|
|
||
|
|
Those porting from autotools should note that meson does not add
|
||
|
|
endianness to the name of the cpu_family. For example, autotools
|
||
|
|
will call little endian PPC64 "ppc64le", meson will not, you must
|
||
|
|
also check the `.endian()` value of the machine for this information.
|
||
|
|
|
||
|
|
## Operating system names
|
||
|
|
|
||
|
|
These are provided by the `.system()` method call.

## Compiler and linker flag environment variables
|
||
|
|
|
||
|
|
These environment variables will be used to modify the compiler and
|
||
|
|
linker flags.
|
||
|
|
|
||
|
|
It is recommended that you **do not use these**. They are provided purely to
|
||
|
|
for backwards compatibility with other build systems. There are many caveats to
|
||
|
|
their use, especially when rebuilding the project. It is **highly** recommended
|
||
|
|
that you use [the command line arguments](#language-arguments-parameter-names)
|
||
|
|
instead.

## Function Attributes
|
||
|
|
|
||
|
|
These are the parameters names that are supported using
|
||
|
|
`compiler.has_function_attribute()` or
|
||
|
|
`compiler.get_supported_function_attributes()`
|
||
|
|
|
||
|
|
### GCC `__attribute__`
|
||
|
|
|
||
|
|
These values are supported using the GCC style `__attribute__` annotations,
|
||
|
|
which are supported by GCC, Clang, and other compilers.

\* *Changed in 0.52.0* the "visibility" target no longer includes

|
"protected", which is not present in Apple's clang.
|
||
|
|
|

|
|
† *New in 0.52.0* These split visibility attributes are preferred to the plain
|
||
|
|
"visibility" as they provide narrower checks.

### MSVC __declspec
|
||
|
|
|
||
|
|
These values are supported using the MSVC style `__declspec` annotation,
