From: sje397 Date: Thu, 10 Nov 2011 14:20:17 +0000 (+1100) Subject: Added QRCode generation functions via libqrencode. Switch on with USE_QRENCODE=1. X-Git-Tag: v0.4.0-unstable~129^2~300^2 X-Git-Url: https://git.novaco.in/?a=commitdiff_plain;h=22123c85f3722abad896aebb564a89d88da92e81;hp=3528650560a2c417da2303869c743da019defc6d;p=novacoin.git Added QRCode generation functions via libqrencode. Switch on with USE_QRENCODE=1. Amended build docs for Linux and OSX, and OSX makefile.
