Subject: [dpdk-dev] [dpdk v1] net/mlx5: fix possible building error
Date: Sat, 29 Feb 2020 18:27:20 +0800	[thread overview]
Message-ID: <1582972040-7026-1-git-send-email-xiangxia.m.yue@gmail.com> (raw)

From: Tonghao Zhang <xiangxia.m.yue@gmail.com>

When setting the CONFIG_RTE_BUILD_SHARED_LIB to y,
and build the mlx5 pmd, there is a building error.
To fix it, add RTE_IBVERBS_LINK_DLOPEN to include
relative codes.

> mlx5_common.o: In function `mlx5_glue_init':
> drivers/common/mlx5/mlx5_common.c:324: undefined reference to `dlclose'

Fixes: 7b4f1e6bd367 ("common/mlx5: introduce common library")
