Can you send your build error ? (maybe in a separate thread ?)

I encountered these problems as well.
- igb_uio module does not check if you disable vmxnet3-uio pmds, it will
always try to take over vmxnet3 devices.
I have a patch waiting in my working dir to cleanly disable vmxnet3-uio pmd.
- If you don't bind vmxnet3 devices to uio, but forget to enable
vmxnet3-usermap pmd (by specifiying -d librte_pmd_vmxnet3.so), then
internal vmxnet3-uio pmd will try to initialise and crash.
I did not look any deeper into this, the easiest way is to disable
vmxnet3-uio pmd + apply the patch I will send in a few minutes, as a first
workaround.
