We have updated the version of spdk we use in our build to bcfb2b2b9c5f22bceee4e31d0a191f73adebbe9f (from 051297114cb393d3eb1169520d474e81b4215bf0) but now I can't build the fio_plugin. (using fio 3.3 as per https://github.com/spdk/spdk/blob/master/examples/nvme/fio_plugin/README.md)

This is on Fedora 28. Has anyone else experienced this or have any suggestions?

Hi Tom,

I've been using fio plug-in a lot lately and haven't had any issues following the readme you mention below although for reason I thought there was a configure step in the /fio dir before making there. I'm using Fedora29 though with gcc (GCC) 8.3.1 20190223 (Red Hat 8.3.1-2).  I dunno maybe run through the steps again and capture all of the commands and output along the way, maybe something will jump out if someone else doesn't chime in before with an answer.

Thx
Paul
