# Built-in options
|
|
|
|
|
|
|
|
|
|
Meson provides two kinds of options: [build options provided by the
|
|
|
|
|
build files](Build-options.md) and built-in options that are either
|
|
|
|
|
universal options, base options, compiler options.
|
|
|
|
|
|
|
|
|
|
## Universal options
|
|
|
|
|
|
|
|
|
|
A list of these options can be found by running `meson --help`. All
|
|
|
|
|
these can be set by passing to `meson` (aka `meson setup`) in any of
|
|
|
|
|
these ways: `--option=value`, `--option value`, `-Doption=value`.
|
|
|
|
|
|
|
|
|
|
They can also be edited after setup using `meson configure`.
|
|
|
|
|
|
|
|
|
|
Installation options are all relative to the prefix, except:
|
|
|
|
|
|
|
|
|
|
* When the prefix is `/usr`: `sysconfdir` defaults to `/etc`, `localstatedir` defaults to `/var`, and `sharedstatedir` defaults to `/var/lib`
|
|
|
|
|
* When the prefix is `/usr/local`: `localstatedir` defaults to `/var/local`, and `sharedstatedir` defaults to `/var/local/lib`
|
|
|
|
|
|
|
|
|
|
| Option | Default value | Description |
|
|
|
|
|
| ------ | ------------- | ----------- |
|
|
|
|
|
| prefix | see below | Installation prefix |
|
|
|
|
|
| libdir | see below | Library directory |
|
|
|
|
|
| libexecdir | libexec | Library executable directory |
|
|
|
|
|
| bindir | bin | Executable directory |
|
|
|
|
|
| sbindir | sbin | System executable directory |
|
|
|
|
|
| includedir | include | Header file directory |
|
|
|
|
|
| datadir | share | Data file directory |
|
|
|
|
|
| mandir | share/man | Manual page directory |
|
|
|
|
|
| infodir | share/info | Info page directory |
|
|
|
|
|

|
|
|
|
|
| sysconfdir | etc | Sysconf data directory |
|
|
|
|
|
| localstatedir | var | Localstate data directory |
|
|
|
|
|
| sharedstatedir | com | Architecture-independent data directory |
|
|
|
|
|
| werror | false | Treat warnings as errors |
|
|
|
|
|
| warnlevel {1, 2, 3} | 1 | Set the warning level. From 1 = lowest to 3 = highest |
|
|
|
|
|
| layout {mirror,flat} | mirror | Build directory layout. |
|
|
|
|
|
| default-library {shared, static, both} | shared | Default library type. |
|
|
|
|
|
| backend {ninja, vs,<br>vs2010, vs2015, vs2017, xcode} | | Backend to use (default: ninja). |
|
|
|
|
|
| stdsplit | | Split stdout and stderr in test logs. |
|
|
|
|
|
| errorlogs | | Whether to print the logs from failing tests. |
|
|

|
|
|
|
|
| wrap-mode {default, nofallback, nodownload, forcefallback} | | Special wrap mode to use |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
`prefix` defaults to `C:/` on Windows, and `/usr/local/` otherwise. You should always
|
|
|
|
|
override this value.
|
|
|
|
|
|
|
|
|
|
`libdir` is automatically detected based on your platform, but the
|
|
|
|
|
implementation is [currently buggy](https://github.com/mesonbuild/meson/issues/2038)
|
|
|
|
|
on Linux platforms.
|
|
|
|
|
|
|
|
|
|
There are various other options to set, for instance the backend to use and
|
|
|
|
|
the path to the cross-file while cross compiling, which won't be repeated here.
|
|
|
|
|
Please see the output of `meson --help`.
|
|
|
|
|
|
|
|
|
|
## Base options
|
|
|
|
|
|
|
|
|
|
These are set in the same way as universal options, but cannot be shown in the
|
|
|
|
|
output of `meson --help` because they depend on both the current platform and
|
|
|
|
|
the compiler that will be selected. The only way to see them is to setup
|
|
|
|
|
a builddir and then run `meson configure` on it with no options.
|
|
|
|
|
|
|
|
|
|
The following options are available. Note that they may not be available on all
|
|
|
|
|
platforms or with all compilers:
|
|
|
|
|
|
|
|
|
|
| Option | Default value | Possible values | Description |
|
|
|
|
|
| ----------- | ------------- | --------------- | ----------- |
|
|
|
|
|
| b_asneeded | true | true, false | Use -Wl,--as-needed when linking |
|
|
|
|
|
| b_bitcode | false | true, false | Embed Apple bitcode, see below |
|
|
|
|
|
| b_colorout | always | auto, always, never | Use colored output |
|
|
|
|
|
| b_coverage | false | true, false | Enable coverage tracking |
|
|
|
|
|
| b_vscrt | from_buildtype| none, md, mdd, mt, mtd, from_buildtype | VS runtime library to use (since 0.48.0) |
|
|
|
|
|
| b_lundef | true | true, false | Don't allow undefined symbols when linking |
|
|
|
|
|
| b_lto | false | true, false | Use link time optimization |
|
|
|
|
|
| b_ndebug | false | true, false, if-release | Disable asserts |
|
|
|
|
|
| b_pch | true | true, false | Use precompiled headers |
|
|
|
|
|
| b_pgo | off | off, generate, use | Use profile guided optimization |
|
|
|
|
|
| b_sanitize | none | see below | Code sanitizer to use |
|
|
|
|
|
| b_staticpic | true | true, false | Build static libraries as position independent |
|
|
|
|
|
|
|
|
|
|
The value of `b_sanitize` can be one of: `none`, `address`, `thread`,
|
|
|
|
|
`undefined`, `memory`, `address,undefined`.
|
|
|
|
|
|
|
|
|
|
### Notes about Apple Bitcode support
|
|
|
|
|
|
|
|
|
|
`b_bitcode` will pass `-fembed-bitcode` while compiling and will pass
|
|
|
|
|
`-Wl,-bitcode_bundle` while linking. These options are incompatible with
|
|
|
|
|
`b_asneeded`, so that option will be silently disabled.
|
|
|
|
|
|
|
|
|
|
[Shared modules](#Reference-manual.md#shared_module) will not have bitcode
|
|
|
|
|
embedded because `-Wl,-bitcode_bundle` is incompatible with both `-bundle` and
|
|
|
|
|
`-Wl,-undefined,dynamic_lookup` which are necessary for shared modules to work.
|
|
|
|
|
|
|
|
|
|
## Compiler options
|
|
|
|
|
|
|
|
|
|
Same caveats as base options above.
|
|
|
|
|
|
|
|
|
|
The following options are available. Note that both the options themselves and
|
|
|
|
|
the possible values they can take will depend on the target platform or
|
|
|
|
|
compiler being used:
|
|
|
|
|
|
|
|
|
|
| Option | Default value | Possible values | Description |
|
|
|
|
|
| ------ | ------------- | --------------- | ----------- |
|
|
|
|
|
| c_args | | free-form comma-separated list | C compile arguments to use |
|
|
|
|
|
| c_link_args | | free-form comma-separated list | C link arguments to use |
|
|
|
|
|
| c_std | none | none, c89, c99, c11, gnu89, gnu99, gnu11 | C language standard to use |
|
|
|
|
|
| c_winlibs | see below | free-form comma-separated list | Standard Windows libs to link against |
|
|
|
|
|
| cpp_args | | free-form comma-separated list | C++ compile arguments to use |
|
|
|
|
|
| cpp_link_args| | free-form comma-separated list | C++ link arguments to use |
|
|
|
|
|
| cpp_std | none | none, c++98, c++03, c++11, c++14, c++17, <br/>c++1z, gnu++03, gnu++11, gnu++14, gnu++17, gnu++1z | C++ language standard to use |
|
|
|
|
|
| cpp_debugstl | false | true, false | C++ STL debug mode |
|
|
|
|
|
| cpp_eh | sc | none, a, s, sc | C++ exception handling type |
|
|
|
|
|
| cpp_winlibs | see below | free-form comma-separated list | Standard Windows libs to link against |
|
|
|
|
|
|
|
|
|
|
The default values of `c_winlibs` and `cpp_winlibs` are in compiler-specific
|
|
|
|
|
argument forms, but the libraries are: kernel32, user32, gdi32, winspool,
|
|
|
|
|
shell32, ole32, oleaut32, uuid, comdlg32, advapi32.
|
|
|
|
|
|
|
|
|
|
c_args, cpp_args, c_link_args, and cpp_link_args only affect native builds,
|
|
|
|
|
when cross compiling they will not be applied to binaries or libraries
|
|
|
|
|
targeting the host system, only those being run on the build system.
