Meson
Meson is an open source meta build system meant to be fast and user-friendly.
In Nixpkgs, meson comes with a setup hook that overrides the configure, check, and install phases.
Being a meta build system, meson needs an accompanying backend. In the context of Nixpkgs, the typical companion backend is Ninja, that provides a setup hook registering ninja-based build and install phases.
Variables controlling Meson
Meson Exclusive Variables
mesonFlags
Controls the flags passed to meson setup during configure phase.
mesonWrapMode
Which value is passed as
-Dwrap_mode=
to. In Nixpkgs the default value is nodownload, so that no subproject will be
downloaded (since network access is already disabled during deployment in
Nixpkgs).
Note: Meson allows pre-population of subprojects that would otherwise be downloaded.
mesonBuildType
Which value is passed as
--buildtype to
meson setup during configure phase. In Nixpkgs the default value is plain.
mesonAutoFeatures
Which value is passed as
-Dauto_features=
to meson setup during configure phase. In Nixpkgs the default value is
enabled, meaning that every feature declared as "auto" by the meson scripts
will be enabled.
mesonCheckFlags
Controls the flags passed to meson test during check phase.
mesonInstallFlags
Controls the flags passed to meson install during install phase.
mesonInstallTags
A list of installation tags passed to Meson's commandline option
--tags during
install phase.
Note: mesonInstallTags should be a list of strings, that will be converted to
a comma-separated string that is recognized to --tags.
Example: mesonInstallTags = [ "emulator" "assembler" ]; will be converted to
--tags emulator,assembler.
dontUseMesonConfigure
When set to true, don't use the predefined mesonConfigurePhase.
dontUseMesonCheck
When set to true, don't use the predefined mesonCheckPhase.
dontUseMesonInstall
When set to true, don't use the predefined mesonInstallPhase.
Honored variables
The following variables commonly used by stdenv.mkDerivation are honored by
