[dpdk-users] How do I enable netvsc with meson build?

[dpdk-users] How do I enable netvsc with meson build?

[Dennis Montgomery]

Hello DPDK community,

I’ve mislaid my copy of “Building DPDK with Meson for Dummies” and can’t figure this out: how do I enable the drivers/net/netvsc pmd with meson?  I’m finding that it’s disabled due to a missing dependency, but the dependency it claims to be missing… seems to be there?

Specifically it’s complaining about the vmbus driver.  That’s included in the meson.log snippet attached below, under “Drivers Enabled”/bus.  I’m lost.

Thanks for your help,

Dennis Montgomery

Did this get resolved? I don't see this with 20.11.
Do you have the correct version of meson?

Re: [dpdk-users] How do I enable netvsc with meson build?

[Dennis Montgomery]

It did get resolved, by migrating the rest of the way to 20.11.  I was on 20.08 at the time (sorry, I missed that key detail in my original post) and was most of the way to 20.11 in another branch – and found that netvsc was enabled/working there so I gave up on the 20.08 effort.

Thanks for following up.

Dennis
