From ccee5d18a470242ee86c58c9203b40ca112a49b3 Mon Sep 17 00:00:00 2001 From: Luca Boccassi Date: Thu, 10 Jan 2019 17:28:06 +0000 Subject: [PATCH] build: mention -march in pkg-config description Applications need to at least match DPDK's -march option to build successfully due to some static inline functions in the public headers. This might cause problems, especially in distributions, so add a note in the pkg-config description.
