Subject: [PATCH v7 1/2] Simplify the ifdefs in rte.app.mk
Date: Mon, 11 May 2015 18:14:25 -0500	[thread overview]
Message-ID: <1431386066-6147-1-git-send-email-keith.wiles@intel.com> (raw)
In-Reply-To: <017274>

    Trying to simplify the ifdefs in rte.app.mk to make the code
    more readable and maintainable by moving LDLIBS variable to use
    the same style as LDLIBS-y being used in the rest of the code.

    Added a new variable called EXTRA_LDLIBS to be used by example apps
    instead of using LDLIBS directly. The new internal variable _LDLIBS
    should not be used outside of the rte.app.mk file.
