I know it might not mean anything to the non-techs, and it might seem insignificant to the uber-techs.

I have successfully built the Gridcoin client on Xenial 16.04.4 with proper libraries, and confirmed it sees my testnet wallet, and overall is just working like it should. (No testplan per se.)

This is a major accomplishment for me, and makes me very excited. It takes 16 minutes to compile with 3 cores of i7-6820HQ CPU @ 2.70GHz and 3.2GB RAM.

I get some QT warnings, but they do not seem to break anything:

/usr/include/x86_64-linux-gnu/qt5/QtCore/qlogging.h:112:73: note: in expansion of macro ‘Q_ATTRIBUTE_FORMAT_PRINTF’
void critical(CategoryFunction catFunc, const char *msg, ...) const Q_ATTRIBUTE_FORMAT_PRINTF(3, 4);


Here is my build environment setup procedure.
