From 9a7d8509efe4ac509b082cbffa24e52a7697926c Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 5 Sep 2017 14:36:14 +0200 Subject: meson: basic build system support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Why? Because it's fast. Like really, really fast. Some data (from a snb laptop, so rather lower-powered): - Incremental build after $ touch lib/igt_core.c with meson: 0.6s It notices that the symbol list of the libigt.so hasn't changed and doesn't bother re-linking the almost 300 binaries we have. make -j 6 for the same scenario takes 44s. - Incremental build with nothing changed: make: 0.7s, meson: 0.2s This means stuff like --disable-git-hash is entirely pointless with meson, it's faster than a make ever can be (with 0.6s). - Reconfigure stage: ninja reconfigure 0.8s vs. ./configure 8.6s) - Running tests, after a full build: ninja test 6s vs. make check 24s - Full build (i.e. including ./autogen.sh respectively meson build), including tests, from a pristine git checkout. automake 2m49s vs. meson 44s.
