linking error with dpdk

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

Usually problems with installing OVS with DPDK result from not carefully
following the instructions in INSTALL.DPDK.md, which say specifically
what version of DPDK to use and specifically how to build it.

This is not correct,  target also should be included i.e <LOCATION>/dpdk-<version>/x86_64-native-linuxapp-gcc

This looks ok.

Well, there was a recent patch  with subject "NUMA Aware vhost user" that introduced a dependency on libnuma-dev package. 
In case you don't have it installed you get the above error( it's not appropriate though!). Hope this resolves your issue.

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,
