Subject: [dpdk-dev] [PATCH v2 4/6] mk: prevent overlinking in applications
Date: Fri, 10 Jun 2016 15:19:07 +0200	[thread overview]
Message-ID: <1465564749-1405-5-git-send-email-thomas.monjalon@6wind.com> (raw)
In-Reply-To: <1465564749-1405-1-git-send-email-thomas.monjalon@6wind.com>

From: Ferruh Yigit <ferruh.yigit@intel.com>

Replace --no-as-needed linker flag with --as-needed flag, which will
only link libraries directly called by application.
It can be achieved now that the libraries dependencies are handled
properly.
