The name of the dpdk library changed between dpsk-2.0.0 and dpdk-2.1.0. Ovs-2.4 builds against dpdk-2.0.0. You will need some patches to allow it to build against dpdk-2.1.0.

Subject: [ovs-discuss] ovs-dpdk:cannot link with dpdk
Mr Dear:
I am using ovs on DPDK platform,and encountered the following issue: "configure: error: cannot link with dpdk".
Bellows are the details of the commands.
Here are my files-list:
[root at root /home/wangrong]#ls
dpdk-2.1.0 iperf-2.0.2 openvswitch-2.4.0 ovs-2.4.0 pcap tar-gz test
(1)Make DPDK
export DPDK_DIR=/home/wangrong/dpdk-2.1.0
cd $DPDK_DIR
vim config/common_linuxapp <修改之后编译成单个lib大文件,支持vhost>
CONFIG_RTE_BUILD_COMBINE_LIBS=y
CONFIG_RTE_LIBRTE_VHOST=y
CONFIG_RTE_LIBRTE_VHOST_USER=n
make install T=x86_64-native-linuxapp-gcc //若提示fuse头文件错误,解决方法见附1.
export RTE_SDK=/home/wangrong/dpdk-2.1.0
export RTE_TARGET=x86_64-native-linuxapp-gcc
export EXTRA_CFLAGS="-O0 -g"
cd $DPDK_DIR/lib/librte_vhost/eventfd_link <为了支持vhost,需要编译该内核模块>
make
(2)Make OVS
export OVS_DIR=/home/wangrong/ovs-2.4.0
export DPDK_BUILD=$DPDK_DIR/x86_64-native-linuxapp-gcc
cd $OVS_DIR
./boot.sh
./configure --with-dpdk=$DPDK_BUILD CFLAGS="-g -O2 -Wno-cast-align" <编译OVS的时候指定加入DPDK>
Here comes the ERROR:configure: error: cannot link with dpdk
This error confuses me and I come to for help.
Thanks a lot.
Sincerely youres WangRong
