From mboxrd@z Thu Jan 1 00:00:00 1970 From: Panu Matilainen Subject: [PATCH] eal: fix regression of plugins always requiring full path Date: Mon, 23 Nov 2015 14:05:55 +0200 Message-ID: <2ce33879359cd5d15dbb7fb10687d484dd187348.1448280355.git.pmatilai@redhat.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 AF4148E91 for ; Mon, 23 Nov 2015 13:06:02 +0100 (CET) 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" The added error checking on plugin initialization in commit 9f8eb1d9ca0f56d6292db5858c52e6873d0abe51 broke the ability of loading plugins by their basename from default linker locations. Only use stat() for directory discovery and leave error handling to dlopen() to restore former behavior.
