Subject: [ndctl PATCH v3 14/16] build: Add meson build infrastructure
Date: Wed, 05 Jan 2022 13:32:53 -0800	[thread overview]
Message-ID: <164141837329.3990253.11664056350173402543.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <164141829899.3990253.17547886681174580434.stgit@dwillia2-desk3.amr.corp.intel.com>

Build times improve from 10s of seconds to sub-second builds especially
when ccache gets involved and the only change is a git version bump. Recall
that every time the version changes with autotools it does a reconfigure.
With meson only the objects that depend on the version string are rebuilt.
So the primary motivation is to make the ndctl project more enjoyable to
develop.

Tools, libraries, documentation, and tests all seem to be working. The
remaining work is to redo the rpm build infrastructure, and validate that
installation is working as expected.

Given the long standing momentum on the old build system it is still kept
functional for now. The only compatibility hack when moving from an
autotools build to a meson build is to delete the config.h files generated
by the old system in favor of the unified configuration header build from
the config.h.meson template.
