Subject: [dpdk-dev] [PATCH v6 1/2] Simplify the ifdefs in rte.app.mk.
Date: Fri,  1 May 2015 09:22:31 -0500	[thread overview]
Message-ID: <1430490152-973-1-git-send-email-keith.wiles@intel.com> (raw)

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. The makefiles
can still use LDLIBS, but I would suggest using EXTRA_LDLIBS instead.
