[dpdk-dev] linking error with dpdk

[Raja Jayapal]

Hi All,

I am trying to install dpdk with ovs, but am getting the linking errors.
Downloaded and tried with dpdk 2.0/2.2/16.04 and latest ovs.

DPDK : wget http://dpdk.org/browse/dpdk/snapshot/dpdk-2.0.0.tar.gz and wget http://dpdk.org/browse/dpdk/snapshot/dpdk-2.2.0.tar.gz
OVS : git clone https://github.com/openvswitch/ovs.git

 ./configure --with-dpdk=/home/ubuntu/raja2/dpdk-2.2.0

Installed dpdk successfully, but when i build ovs with dpdk i am getting the linking error in all the three versions of dpdk.
Is there any specific version in which the dpdk-ovs will only work, if so please let me know.

Thanks,
Raja

Hi Raja,

OVS master branch supports DPDK16.04, I just confirmed it is working.

Please follow instruction on INSTALL.DPDK.md in OVS repo.

Briefly:
export DPDK_DIR=/usr/src/dpdk-16.04
cd $DPDK_DIR
make install T=x86_64-native-linuxapp-gcc DESTDIR=install
export DPDK_BUILD=$DPDK_DIR/x86_64-native-linuxapp-gcc
cd $(OVS_DIR)
./configure --with-dpdk=$DPDK_BUILD
make

Regards,
ferruh

You need to have CONFIG_RTE_BUILD_COMBINE_LIBS=y if you are trying 
dpdk-2.2.0 or less.

As Ferruh replied earlier, refer to dpdk version what INSTALL.DPDK.md 
suggests.

Thanks,
