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. |

to do this in cross builds. |

## 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. |

*The old environment variales are still supported, but are deprecated |
|
and will be removed in a future version of Meson.* |
|
|
|
## Environment variables per machine |
|
|
|
Since *0.54.0*, Following Autotool and other legacy build systems, |
|
environment variables that affect machine-specific settings come in |
|
pairs: for every bare environment variable `FOO`, there is a suffixed |
|
`FOO_FOR_BUILD`, where `FOO` just affects the host machine |
|
configuration, while `FOO_FOR_BUILD` just affects the build machine |
|
configuration. For example: |
|
|
|
- `PKG_CONFIG_PATH_FOR_BUILD` controls the paths pkg-config will search for |
|
just `native: true` dependencies (build machine). |
|
|
|
- `PKG_CONFIG_PATH` controls the paths pkg-config will search for just |
|
`native: false` dependencies (host machine). |
|
|
|
This mirrors the `build.` prefix used for (built-in) Meson options, |
|
which has the same meaning. |
|
|
|
This is useful for cross builds. In the native builds, build = host, |
|
and the unsuffixed environment variables alone will suffice. |
|
|
|
Prior to *0.54.0*, there was no `_FOR_BUILD`-suffixed variables, and |
|
most environment variables only effected native machine |
|
configurations, though this wasn't consistent (e.g. `PKG_CONFIG_PATH` |
|
still affected cross builds).
