From mboxrd@z Thu Jan 1 00:00:00 1970 From: Panu Matilainen Subject: [PATCH] drivers: fix shared library dependencies to external libraries Date: Wed, 21 Oct 2015 17:18:27 +0300 Message-ID: Cc: nicolas.pernas.maradei@emutex.com To: dev@dpdk.org Return-path: Received: from mx1.redhat.com (mx1.redhat.com [209.132.183.28]) by dpdk.org (Postfix) with ESMTP id 4ED089386 for ; Wed, 21 Oct 2015 16:18:36 +0200 (CEST) List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" Similar to commit 113c8e13c4201eee207723571f83aaf285277d75, but for bnx2x and pcap PMDs. Requiring applications to know about library internal details like dependencies to external helper libraries is a limitation of static linkage, shared libraries should always know their own dependencies for sane operation. This is especially highlighted with dlopen()'ed items, having applications link against about plugin internal dependencies goes on the side of absurd.
