Thanks--I'll give that a try when the dust clears here.

In November of 2016, I cross-compiled UHD (git-cloned) on my Ubuntu 16.04

2016.3. Life has passed me by and now I need to re-build the library using
the Petalinux 2017.3 toolchain. I have only a few weeks to a major
milestone, with no time to adapt to all the changes that have no doubt
occurred during that gap. Is there any way to use the older UHD with the
newer Petalinux tools?
You might be able to just remove all usage of Neon. Try removing these
lines:
https://github.com/EttusResearch/uhd/blob/6013a511370b9452020adfc72d7893f1c3bb2963/host/lib/convert/CMakeLists.txt#L65-L79
Of course, you'll lose the Neon assembly acceleration. Depending on your
app, that might still be fast enough.

Here's the first of many similar errors:

Any help will be appreciated.
