Proper Setup of Py2App

This assumes you have a proper Framework'd Python installation.

brew install python --framework 

Install Qt v4.7.1

I've patched the Qt v4.7.1 installation process to remove libpng dependencies. Use this:

brew install https://gist.github.com/raw/519418/qt.rb --universal

If you are installing into a virtualenv, activate it now.

Build SIP for x86_64 and i386

curl -O http://www.riverbankcomputing.com/static/Downloads/sip4/sip-4.12.1.tar.gz
tar -xzvf sip-4.12.1.tar.gz && cd sip-4.12.1
python configure.py --arch=x86_64 --arch=i386
make -j
make install

Build PyQT4

curl -O http://www.riverbankcomputing.com/static/Downloads/PyQt4/PyQt-mac-gpl-4.8.3.tar.gz
tar -xzvf PyQt-mac-gpl-4.8.3.tar.gz && cd PyQt-mac-gpl-4.8.3
python configure.py -q /usr/local/Trolltech/Qt-4.7.1/bin/qmake
make -j
make install

hey kenneth,

the link to the patch in qt.rb above is no longer functioning and should be replaced by:

http://qt.gitorious.org/+qt-developers/qt/lighthouse/commit/9f18a1ad5ce32dd397642a4c03fa1fcb21fb9456?format=patch

I forked the gist, made the change and all appears to be working well... now just sitting here twiddling my thumbs as qt compiles.

-b

haha, thanks! libpng is going to be removed from homebrew soon, so I have to add that too. It's not technically needed, but py2app doesn't suck in the x11 libpng because it thinks it's a system library, but many people don't have it.

no problem ; )

well, things didn't turn out super-great... looks like Qt is still after the PNG dependency:
