2 years ago RPM is looking for symbols and libraries available in other RPM packages, not actual files on the filesystem. So, you need a DPDK RPM package installed.
You also need the RPM that is the same with which you built OVS with. So, you need to either build a DPDK package, install it and build OVS with it, or, since RHEL8 happened to have a compatible version of DPDK, install dpdk-devel and dpdk packages from RHEL repositories and build with them. These packages do not provide static libraries, IIRC, so you have to use --with-dpdk=shared.
On a clean system, you should be able to install dpdk-devel and dpdk packages from RHEL8 repo and build an OVS 2.17+ with it with the following spec change:

Note: already posted about some of this here. Already tried following the instructions here. DPDK installs fine. But Openvswitch will not install. There are not clear instructions that I could find on how to install Openvswitch on RHEL8. This page states this:
However I could not find anyway to install via yum or dnf, none of the current repos include
openvswitchoropenvswitch-dpdkI shifted to installing using an RPM. You can read about how I was able to do this with a regular ovs deployment here. The process works for configuring ovs without--with-dpdk=<value>parameter. However when I include that parameter in the .spec file configure section, then create an rpm, the rpm will not install. I get these errors:DPDK is installed and I can find with pkg-config
I tried using
--with-dpdk=static--with-dpdk=sharedand--with-dpdk=yes(Which I believe is the same as static) none worked. I was able to compile an install on Ubuntu 18.04 with out these issues.I am not clear on why the rpm install needs these shared libraries but the non dpdk installs dont. It looks like many of these dependencies are shared objects. Were they not installed? is dpdk flavor installs looking for these? How do I correct this problem so I can install ovs with dpdk?
Also if anyone knows how to fix the Python3 conflict errors that would be great. I just ignore them with
--nodepson install of the rpm.UPDATE: well it seems I could just
yum install dpdk, and that took care of most of the dependencies. Whats left is the following:All of these
librte_*are related to dpdk in some way I think. Not sure why these are not being found.
