I think you should define SHARED variable instead of LIB.
Please confirm it works.

By the way, it is the old way of doing shared library. It should be dep=
recated=20
and replaced by the new option RTE_BUILD_SHARED_LIB.

Could you also try the new method by using rte.extlib.mk with option=20=

CONFIG_RTE_BUILD_SHARED_LIB=3Dy ?

Thank you
--=20
