Hi, If using OVS v2.4 please ensure that --with-dpdk=/home/wangrong/dpdk-2.1.0/x86_64-native-linuxapp-gcc Do not use a relative path. Or else if using a relative path, you need to apply this patch https://patchwork.ozlabs.org/patch/518491/ If including additional CFLAGS, you can follow this format: ./configure --with-dpdk=/home/wangrong/dpdk-2.1.0/x86_64-native-linuxapp-gcc 'CFLAGS=-g -O2 -Wno-cast-align' Ciara > > 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 > > > > > > > _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
