Expected Results: What should have happened, were the bug not present.
Pass all make check & distcheck
Additional Information:
The analyse is that libtool did not add DPDK_LIBS variable in the LDFLAGS.
A Solution is: /example/ddf_app/Makefile.am
include $(top_srcdir)/example/Makefile.inc
bin_PROGRAMS = odp_ddf_app$(EXEEXT)
-odp_ddf_app_LDFLAGS = $(AM_LDFLAGS) -shared
+odp_ddf_app_LDFLAGS = $(AM_LDFLAGS) $(DPDK_LIBS) -shared
odp_ddf_app_CFLAGS = $(AM_CFLAGS) -I${top_srcdir}/example
