From 20afd76a504155e947c770783ef5023e87136ad8 Mon Sep 17 00:00:00 2001 From: Olivier Matz Date: Fri, 28 Feb 2014 18:25:40 +0100 Subject: [PATCH] mk: use whole-archive option to keep unused symbols To fully support dpdk extensions (loading of .so), all symbols provided by dpdk libraries must be available in the binaries: before this patch, unused functions/variables from dpdk static libraries could be stripped by the linker because they are not used. These symbols can be used by a dpdk extension that is loaded at runtime with the -d option. Adding --whole-archive when generating a binary solves this issue.
