= QtD on Mac OS X Case Study =

This is a description of how I got QtD working on a Mac.

Though I'm sure that there is a way to do it, I was not able to use a Qt installed using frameworks. The significance of this is that

 1. the binary !QtCreator SDK installs using frameworks, so you can't use its Qt
 2. not using frameworks means that you can't use Cocoa-Qt or 64-bit Qt
 3. so, we must use 32-bit Carbon-Qt

So, I had to download the Qt source and build a no-frameworks version.

Make sure correct versions of dmd, qmake, and cmake are in your path (use which to check)

build QtD as described in build instructions for Linux from wiki (cmake using defaults)

= Build examples/tutorials/tutorial/t1 =

edit build.sh like this:
{{{
#! /bin/bash

dmd main.d \
-I../../../../ \
-I../../../../qt/d2 \
-I../../../../bld/build/ \
-I../../../../bld/build/qt \
-I../../../../bld/build/include \
-L-L../../../../lib \
-L-L../../../../bld/build/lib \
-L-L/usr/local/Trolltech/Qt-4.5.2/lib \
-L-lqtdgui \
-L-lqtdcore \
-L-lQtCore \
-L-lQtGui \
-L-lstdc++ \
-oft1
}}}

build t1 using build.sh

then run ./t1

It worked for me; good luck!
