short-description: Setting up native compilation

# Persistent native environments
|
||
|
|
|
||
|
|
New in 0.49.0
|
||
|
|
|
||
|
|
Meson has [cross files for describing cross compilation environments](Cross-compilation.md),
|
||
|
|
for describing native environments it has equivalent "native files".
|
||
|
|
|
||
|
|
Natives describe the *build machine*, and can be used to override properties of
|
||
|
|
non-cross builds, as well as properties that are marked as "native" in a cross
|
||
|
|
build.
|
||
|
|
|
||
|
|
There are a couple of reasons you might want to use a native file to keep a
|
||
|
|
persistent environment:
|
||
|
|
|
||
|
|
* To build with a non-default native tool chain (such as clang instead of gcc)
|
||
|
|
* To use a non-default version of another binary, such as yacc, or llvm-config
|
||
|
|
|
||
|
|
## Changing native file settings
|
||
|
|
|
||
|
|
All of the rules about cross files and changed settings apply to native files
|
||
|
|
as well, see [here](Cross-compilation.md#changing-cross-file-settings)
|
||
|
|
|
||
|
|
## Defining the environment
|
||
|
|
|
||
|
|
See the [config-files section](Machine-files.md), for options shared by cross
|
||
|
|
and native files.
|
||
|
|
|
||
|
|
## Native file locations
|
||
|
|
|
||
|
|
Like cross files, native files may be installed to user or system wide
|
||
|
|
locations, defined as:
|
||
|
|
- $XDG_DATA_DIRS/meson/native
|
||
|
|
(/usr/local/share/meson/native:/usr/share/meson/native if $XDG_DATA_DIRS is
|
||
|
|
undefined)
|
||
|
|
- $XDG_DATA_HOME/meson/native ($HOME/.local/share/meson/native if
|
||
|
|
$XDG_DATA_HOME is undefined)
|
||
|
|
|
||
|
|
The order of locations tried is as follows:
|
||
|
|
- A file relative to the local dir
|
||
|
|
- The user local location
|
||
|
|
- The system wide locations in order
|
||
|
|
|
||
|
|
These files are not intended to be shipped by distributions, unless they are
|
||
|
|
specifically for distribution packaging, they are mainly intended for
|
||
|
|
developers.
