[dpdk-dev] [PATCH 16/17] build: add option to version libs using DPDK version

Bruce Richardson bruce.richardson at intel.com
Fri Sep 1 12:04:15 CEST 2017


Normally, each library has it's own version number based on the ABI.
Add an option to have all libs just use the DPDK version number as the
.so version.
