NAME

meson.eclass - common ebuild functions for meson-based packages

DESCRIPTION

This eclass contains the default phase functions for packages which use the meson build system.

SUPPORTED EAPIS

7 8

EXAMPLE

Typical ebuild using meson.eclass:

EAPI=8

inherit meson

...

src_configure() {
        local emesonargs=(
                $(meson_use qt5)
                $(meson_feature threads)
                $(meson_use bindist official_branding)
        )
        meson_src_configure
}

...

FUNCTIONS

emesonargs

Optional meson arguments as Bash array; this should be defined before calling meson_src_configure.

MYMESONARGS

User-controlled environment variable containing arguments to be passed to meson in meson_src_configure.

meson_use <USE flag> [option name]

Given a USE flag and meson project option, outputs a string like:

-Doption=true
-Doption=false

If the project option is unspecified, it defaults to the USE flag.

meson_feature <USE flag> [option name]

Given a USE flag and meson project option, outputs a string like:

-Doption=enabled
-Doption=disabled

If the project option is unspecified, it defaults to the USE flag.

setup_meson_src_configure

Calculate the command line which meson should use, and other relevant variables. Invoke via "${MESONARGS[@]}" in the calling environment. This function is called from meson_src_configure.

meson_src_configure [extra meson arguments]

This is the meson_src_configure function.

meson_src_compile [extra ninja arguments]

This is the meson_src_compile function.

meson_src_test [extra meson test arguments]

This is the meson_src_test function.

meson_install [extra meson install arguments]

Calls meson install with suitable arguments

meson_src_install [extra meson install arguments]

This is the meson_src_install function.

ECLASS VARIABLES

BUILD_DIR: Build directory, location where all generated files should be placed. If this isn't set, it defaults to ${WORKDIR}/${P}-build.
MESON_VERBOSE ?= ON (USER VARIABLE): Set to OFF to disable verbose messages during compilation
EMESON_BUILDTYPE = plain}": The buildtype value to pass to meson setup.
EMESON_SOURCE: The location of the source files for the project; this is the source directory to pass to meson. If this isn't set, it defaults to ${S}
