[ovs-discuss] Difference seen in OVSDB initialization with & without DPDK

The compile error was consistent with using DPDK 1.8 as the mbuf format has changed. I’m not sure why you are getting (bad address) connecting to the db only with DPDK as the DPDK code doesn’t have anything to do with this. I’ve tried to reproduce but am unable to, my logs below. Did you try anything to make sure it’s not system state e.g. reboot; with DPDK; without DPDK; with DPDK ?

Hi
I resolved the below mentioned compiler errors and the build goes fine.
But the issue with the database connectivity still persists. Now the error message seen is different. Pls find the logs below. Let me know how to resolve this:

Hi Kevin
Thanks  for the response.
I used DPDK-1.7.1 and used the same for building the OVS. The OVS version I use is OVS 2.3.1.
I followed the steps mentioned in INSTALL.DPDK in https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md.
I'm getting the below error while executing the make command. Pls let me know whether there exists a patch for resolving the issue. I know how to resolve the last 2 errors.

I notice in the logs you have “/home/controllerdpdk-1.8.0/x86_64-native-linuxapp-gcc”. DPDK 1.8.0 is not supported in OVS at present. There is a patch for it but it was causing an issue with unit test and is being reworked.

I’d suggest rebooting and following the steps in INSTALL.dpdk (with DPDK 1.7.1)

Thanks,
Kevin.
