Dear David,
I still use also DPDK 16 (exactly 16.11.11-1+deb9u2 included in Debian
9), and I have been locked in this version, because I can not compile my
project under DPDK 18 (included in Debian 10).
I would be very happy if you (or someone else) could advise me.
My problem description can be found here:

Best regards,
Gábor

I am surprised to see you are using a 16.04 version.
I recommend using the latest LTS, i.e. 20.11.
For this version, the quick start guide is
https://doc.dpdk.org/guides-20.11/linux_gsg/index.html
refer to nonexistent SETUP.SH, i walking over the docs an do steps to
unsure that DPDK is working at all after installation.
So:

[root@sysman ~]# sudo modprobe vfio-pci

If your server has a iommu, you probably did not configure it.
If you don't have such hw, you need no-iommu support.
