From: Ali Alnubani Date: Wed, 21 Apr 2021 10:06:38 +0000 (+0300) Subject: pipeline: fix build with GCC 4.8.5 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fe4b8c7bcdba8c81b77e5c28b0b55c5a6653a3c6;p=dpdk.git pipeline: fix build with GCC 4.8.5 Compilation on CentOS 7 with gcc version 4.8.5 fails with the following errors: error: 'src_struct_id' may be used uninitialized in this function [-Werror=maybe-uninitialized] error: 'dst_struct_id' may be used uninitialized in this function [-Werror=maybe-uninitialized] This patch fixes the build errors by initializing both variables.
