Hello. I'm sorry for the repeated question.
I finally compiled DPDK successfully (there was a problem in the source code what I downloaded), and I'm moving to compile dpdk-ovs. Before compiling it, I'm trying to binding a network port to igb_uio module. In the dpdk-getting-started-guide, "pci_unbind.py" utility script is used to provide a view of the current state of the network ports on the system, and to bind/unbind those ports from the different kernel modules. The script, however, was not there in tools directory; There were only "igb_uio_bind.py". Is it fine as it is, or do I miss something? I downloaded the DPDK source from http://dpdk.org/browse/dpdk/refs/, and the file was dpdk-1.6.0r2.zip. I compiled both x86-64-defaultlinuxapp-gcc and x86-64-ivshmem-linuxapp-gcc now. Thanks in advance. Best regards Byeong-Gi KIM
