Subject: [dpdk-dev] [PATCH v8 3/4] Add library version extenstion
Date: Thu, 22 Jan 2015 10:49:15 -0500
Message-ID: <1421941756-30948-3-git-send-email-nhorman@tuxdriver.com> (raw)
In-Reply-To: <1421941756-30948-1-git-send-email-nhorman@tuxdriver.com>

To differentiate libraries that break ABI, we add a library version number
suffix to the library, which must be incremented when a given libraries ABI is
broken.  This patch enforces that addition, sets the initial abi soname
extension to 1 for each library and creates a symlink to the base SONAME so that
the test applications will link properly.

Signed-off-by: Neil Horman <nhorman@tuxdriver.com>

CC: "Richardson, Bruce" <bruce.richardson@intel.com>

Change Notes:
v3)
	Made symlinking of libraries conditional on a DSO build

v4)	Removed erroneous newline
	changed @exit 1 to @false
	changed ./$(LIB) to $<
