So, it defines +the variables required by this particular infrastructure, where Meson and its +companion tool, Ninja, are invoked: + +* +FOO_CONFIGURE_CMDS+: the build directory required by Meson is created, and + Meson is invoked to generate the Ninja build file. The options required to + configure the cross-compilation of the package are passed via + +FOO_MESON_OPTS+. + +* +FOO_BUILD_CMDS+: Ninja is invoked to perform the build. + +* +FOO_INSTALL_TARGET_CMDS+: Ninja is invoked to install the files generated + during the build step. + +In order to have Meson available for the build, +FOO_DEPENDENCIES+ needs to +contain +host-meson+. In the example, +host-pkgconf+ and +bar+ are also +declared as dependencies because the Meson build file of +foo+ uses `pkg-config` +to determine the compilation flags and libraries of package +bar+. + +To sum it up, to add a new meson-based package, the Makefile example can be +copied verbatim then edited to replace all occurences of +FOO+ with the +uppercase name of the new package and update the values of the standard +variables. diff --git a/docs/manual/adding-packages.txt b/docs/manual/adding-packages.txt index d577ff030e..e542124cf9 100644 --- a/docs/manual/adding-packages.txt +++ b/docs/manual/adding-packages.txt @@ -34,6 +34,8 @@ include::adding-packages-rebar.txt[] include::adding-packages-waf.txt[] +include::adding-packages-meson.txt[] + include::adding-packages-kernel-module.txt[] include::adding-packages-asciidoc.txt[]
