From 91f7f381063c3d1dba36ff47ab31fe404a03042c Mon Sep 17 00:00:00 2001 From: Eric Le Bihan Date: Tue, 15 May 2018 21:51:52 +0200 Subject: [PATCH] pkg-meson: new infrastructure Add a new infrastructure to ease the development of packages that use Meson as their build system. Signed-off-by: Eric Le Bihan [Thomas: - move global variables definition outside of the inner-meson-package macro - for consistency, remove double quote around value passed to meson in the host configure step. - minor formatting fixes.] Signed-off-by: Thomas Petazzoni --- DEVELOPERS | 1 + package/Makefile.in | 1 + package/pkg-meson.mk | 160 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 162 insertions(+) create mode 100644 package/pkg-meson.mk diff --git a/DEVELOPERS b/DEVELOPERS index d2da9a2f80..a8b98407c3 100644 --- a/DEVELOPERS +++ b/DEVELOPERS @@ -578,6 +578,7 @@ F: package/hicolor-icon-theme/ F: package/jemalloc/ F: package/meson/ F: package/ninja/ +F: package/pkg-meson.mk F: package/rust-bin/ F: package/rust/ F: package/s6/ diff --git a/package/Makefile.in b/package/Makefile.in index 4325f7b3a9..a268016cdf 100644 --- a/package/Makefile.in +++ b/package/Makefile.in @@ -447,3 +447,4 @@ include package/pkg-rebar.mk include package/pkg-kernel-module.mk include package/pkg-waf.mk include package/pkg-golang.mk +include package/pkg-meson.mk diff --git a/package/pkg-meson.mk b/package/pkg-meson.mk new file mode 100644 index 0000000000..507e686068 --- /dev/null +++ b/package/pkg-meson.mk @@ -0,0 +1,160 @@ +################################################################################ +# Meson package infrastructure +# +# This file implements an infrastructure that eases development of +# package .mk files for Meson packages.
