Subject: [dpdk-dev] [PATCH 6/8] mk: use LDLIBS when linking shared libraries
Date: Thu, 29 Jan 2015 15:20:09 +0000	[thread overview]
Message-ID: <1422544811-26385-7-git-send-email-sergio.gonzalez.monroy@intel.com> (raw)
In-Reply-To: <1422544811-26385-1-git-send-email-sergio.gonzalez.monroy@intel.com>

This patch mainly makes use of the LDLIBS variable when linking shared
libraries, setting proper DT_NEEDED entries.

This patch also fix a few nits like syntax highlighting, the command
string (O_TO_S_STR) used for linking shared libraries and the displayed
of dependencies when debugging is enable (D).
