Steps to get a working py2app

py2app.bash

## Roll your own python from source:

wget http://www.python.org/ftp/python/2.6.5/Python-2.6.5.tgz
tar -xzvf Python-2.6.5.tgz && cd Python-2.6.*
./configure --enable-framework=/Library/Frameworks --with-universal-archs=intel --enable-universalsdk=/
make
sudo make install

# Update the symlink for `python` (and check others)

cd /Library/Frameworks/Python.framework/Versions/2.6/bin/
ln -s python2.6-all python

# Download and build Qt - you need to build the cocoa framework version for i386 and x86_64

wget http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.3.tar.gz
tar -xzvf qt-everywhere-opensource-src-4.6.3.tar.gz && cd qt-every*
./configure -cocoa -framework -no-dwarf2 -no-qt3support -release -nomake "examples demos" -no-multimedia -no-audio-backend -no-phonon -no-phonon-backend -no-sql-mysql -no-xmlpatterns -no-accessibility -no-svg -no-webkit -no-javascript-jit -no-script -no-scripttools -no-gif -no-libtiff -no-libpng -no-libmng  -no-libjpeg -no-openssl -no-nis -no-cups -no-iconv -no-dbus -no-webkit -arch "x86 x86_64" -sdk /Developer/SDKs/MacOSX10.6.sdk
make
sudo make install

# make sure you:

ln -s /usr/local/Trolltech/Qt-4.6.3/bin/qmake /usr/local/bin/qmake

# build SIP for x86_64 and i386

wget http://www.riverbankcomputing.co.uk/static/Downloads/sip4/sip-4.10.2.tar.gz
tar -xzvf sip-4.10.2.tar.gz && cd sip*
python configure.py --arch=x86_64 --arch=i386
make
sudo make install

# build PyQT4

wget http://www.riverbankcomputing.co.uk/static/Downloads/PyQt4/PyQt-mac-gpl-4.7.3.tar.gz
tar -xzvf PyQt-mac-gpl-4.7.3.tar.gz && cd PyQt*
python configure.py
make
sudo make install

# ensure macholib is ≥ 1.2.2.  if not:

svn co http://svn.pythonmac.org/macholib/macholib/trunk/macholib/ macholib-svn
cd macholib-svn
python setup.py build
python setup.py install

# install >r90 py2app

svn co http://svn.pythonmac.org/py2app/py2app/trunk/ py2app-svn
cd py2app-svn
python setup.py build
python setup.py install

Running through these steps now. Hopefully it'll work, this has been kicking my ass for days.

Hopefully, this will pay off. I've been building packages with this setup since I posted it... good luck!

It did! Works like a charm. Thanks a million man.

right on! py2app can be fickle, to say the least. i'll try your updated gist using brew on the next install i have to do...

Hmm, apps I make with this are fantastic, but only work on Snow Leopard. Have you found this to be the case?

Yep. I believe this is due to the fact that everything is built for x86_64 and i386. For these to run on Leopard, they should be 3-way binaries, which also includes PPC - meaning that the entire dependency chain would also have to be built as 3-way binaries (x86_64, i386, PPC). What I don't know is if you go through the process above, adding flags for all 3 ARCHs, if that will build a working py2app and working py2app binaries that run on Leopard. I don't know this because I was largely impatient with the process, which was lengthy enough just to get working applications on 10.6 ; )

I settled for killing backwards compatibility on Leopard, which is a non-optimal solution.

Yeah, exact same boat I'm in at the moment. I'm going to load Leopard on a mac this weekend and tinker around and see what happens :)
