Guidelines and HOWTOs/Build from source/Mac

Install Qt (use the official Qt installer, recommended version Qt >= 5.6)

Install homebrew and get some basic dependencies (http://brew.sh/)

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install cmake wget coreutils p7zip gettext ninja python3 bison boost shared-mime-info

Prepare some build directory in your home directory, here we assume:

mkdir ~/kf

Switch to this build dir

cd ~/kf

Get Craft

git clone git://anongit.kde.org/craft.git

Copy Mac OS X config template to right location, should be OK to use out of the box

mkdir etc
cp craft/kdesettings.mac etc/kdesettings.ini

Optional: You might need some extra environment variables

 export CMAKE_LIBRARY_PATH=/usr/local/Cellar/gettext/0.19.8.1/lib
 export CMAKE_INCLUDE_PATH=/usr/local/Cellar/gettext/0.19.8.1/include
 
 export PATH=/usr/local/Cellar/bison/3.0.4/bin:$PATH

Setup environment (path must contain your Qt install, here 5.7 default location and brew's gettext)

export PATH=/Users/cullmann/Qt5.7.0/5.7/clang_64/bin:/usr/local/Cellar/gettext/0.19.7/bin:$PATH
. craft/kdeenv.sh

In this shell, now craft is usable, e.g. to build Kate with all dependencies:

craft kate

To create a app bundle (+ dmg file), you need to have the breeze-icons around:

craft breeze-icons

To do deploy all things, unfortunately at the moment you need a patched macdeployqt. Example scripty for kate can be found on kate.git/mac/emerge-deploy.sh
