Requirements:
-------------

1. Xcode (for the compiler and build tools)
2. A recent version of Qt with carbon support (this allows building Intel and
PPC versions - I'm using qt-mac-carbon-opensource-4.7.1.dmg)

Building Quackle:
-----------------

Unpack the source code. Edit these 3 files:

1. quackle.pro
2. quackleio/quackleio.pro
3. quacker/quacker.pro

In each of these files, find the CONFIG variable, and append the string "x86
ppc" to it. This instructs the compiler to create binaries for both
architectures. Also make sure that CONFIG contains "release" and not "debug".
You don't want to distribute a binary which still has debug symbols in it.

rename the file "quacker.pro" to "Quackle.pro". This is a cosmetic change. It
results in the application being called "Quackle" rather than "quacker".

Now start with the top-level directory. Run "qmake -spec macx-g++" in it,
followed by "make". Repeat these steps in the "quackleio" and then the
"quacker" directories. Now you will have an OSX application bundle called
"Quackle.app" in the "quacker" directory. This bundle contains a fat binary,
with code for both architectures.

Creating a self-contained bundle:
---------------------------------

First, copy the "data" directory from the top-level directory into the bundle:

cp -pR ../data Quackle.app/Contents

Next, copy the icon from an existing Quackle.app bundle into this new one:
select the old Quackle application, press CMD-I, click on the icon and press
CMD-C to copy it. Then select the new application bundle, press CMD-I to open
its properties, click on the blank icon area on the top, and press CMD-V to
paste the icon.

Finally, you need to insert the Qt frameworks into this bundle, so that it can
run stand-alone, without any dependencies. You do that by running:

/Developer/Tools/Qt/macdeployqt Quackle.app -dmg

This will create a file, Quackle.dmg, containing the application bundle. You
can now distribute this. It should run on OSX 10.4, 10.5 and 10.6.
