🙂. I tried many meson commands to wipe/reconfigure my build environment, but I've just blown away the whole build directory and started again, and now it appears to be working ( though I thought I'd tried that before too ). Maybe I missed a trick with reconfiguring meson, I don't know. The PC has also been restarted a few times. The ninja build succeeds ( with warnings ).

Anyway, I'm encouraged that there are people listening out there, and willing to try helping  🙂. 

Thanks folk,
Mark

Well, that's what I have on my Fedora to build mlx drivers.

Btw, librte_common_mlx5 is an internal DPDK driver.
If you still see that this component is disabled after installing
those headers via the devel packages, then maybe you did not
reconfigure your build env.
$ meson --reconfigure <build_dir>


If this is not working, you'll have to look into
<build_dir>/meson-logs/, there may be some useful info in those logs.
