Wow! This is awesome!

@gandrewstone - Rolling through your project and think I am close, just not quite there yet...I attempted to integrate bdb4.8 and could use your help to make this sing!! First, see the error that only pops up right at the end of make...

All of the above is a repeat of itself looping. Below is only at the very end it throws an error. I made a bit of a mess of your clean project hence why I am not checking anything back in however, happy to send to you offline, maybe we can get this up and running...that would be surreal!

So, I am gong to wait, to move forward with the remainder of the build process until I hear back from you...
db-4.8.30.NC.tar.gz
and feel free to ping me on my email zapolator@gmail.com, or better google hangout. On my Ryzen setting the number of cores to 24 it was lightning fast...Would be good to port with CUDA optimizations as well. Best of both worlds, multiple threads on CPU and GPU/CUDA optimizations - heaven on Earth!

Also have attached the tar for the db = db-4.8.30.NC.tar.gz needed for mobile wallets apparently...I am obviously not placing the db files in the correct spot in the project or something else is hosed on my side as in the beginning it throws the same error everytime that it found a db but not one thjat is 4.8 so not happening for mobile wallets. And hence, the rather large mess i have made dropping files everywhere I thought it would be needed to wipe out that error...and failed!

Ciao,
