Subject: [dpdk-dev] ERROR: Invalid module format

Message-ID: <1522256370.1182490.1443410843370.JavaMail.zimbra@viosoft.com> (raw)

Hi all, 
I am building DDPK and OVS as the instruction in https://software.intel.com/en-us/blogs/2015/06/09/building-vhost-user-for-ovs-today-using-dpdk-200 
My scenario is that I have 2 machines, one is called building machine (for build dpdk) and the another is called deploy machine. 
After finishing building DPDK in building machine, I copy all dpdk folders to deploy machine and try to setup DPDK devices in this machine as: 
RTE_SDK=”${HOME}/dpdk-2.0.0
RTE_TARGET =”x86_64-ivshmem-linuxapp-gcc”

# Install and bind UIO interface eth0
sudo modprobe uio
sudo insmod ${RTE_SDK}/${RTE_TARGET}/kmod/igb_uio.ko 


Unfortunately, I got the  error: 
insmod: ERROR: could not insert module ../dpdk-2.0.0/x86_64-ivshmem-linuxapp-gcc/kmod/igb_uio.ko: Invalid module format 

I doubt that the different linux kernel causes the problem (linux kernel in building machine is 3.16.0.49 and in deploy machine is 3.16.0.30) 
but don't know how to fix that. Could you have any solution to build and deploy dpdk in machine with different kernel? 

Thank and best regard!
