Linux Compilation Instructions

[brannondorsey]

I built the CloakCoin v2.1.0 wallet on Ubuntu 16.04 this weekend. I had to fight some dependency issues for a bit, but ultimately got it working nicely 👍. The Linux build instructions on the Wiki are out of date. I've written some updated instructions here if anyone finds them useful. With a bit more testing, it might be nice to include these build instructions somewhere here on the repo for others to find.

Followed your instructions and CloakCoinv2.1.0 compiled without issues on Ubuntu 16.04 and Xubuntu 16.04 Lts. Wiki updated with your contribution. Thanks @brannondorsey .
