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@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
