Subject: [dpdk-dev] [PATCH 4/4] build: generate API documentation with Meson
Date: Fri, 31 Aug 2018 19:20:55 +0100
Message-ID: <20180831182055.30772-5-bluca@debian.org> (raw)
In-Reply-To: <20180831182055.30772-1-bluca@debian.org>

Both a configuration-time "enable_docs" boolean option and an optional
'ninja doc' target are available. Note that due to a Meson bug for now
the latter will only build, but not install the files.

Signed-off-by: Luca Boccassi <bluca@debian.org>
