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

    "We agreed to the Qt opensource license for you.\nIf this is unacceptable you should uninstall."

These steps followed by a simple:

$ python setup.py py2app --includes sip --packages PyQt4

Works perfectly :)

kenneth,

have you tried this with brew through-and-through? i,e. since brew info shows qt and pyqt are the appropriate versions...

-b

@brantfaircloth I haven't had any luck installing Qt or PyQt vis homebrew. Most people have rather specific installations anyway (commercial licenses, etc)

I take that back, the forumla was updated and qt install went great.

PyQt, not so much though. The sip formula installs on system python #lesigh

kenneth - howdy! hope all is well.

one thing to note, i think, is that there may not be a need to add the --arch=ppc flag because brew install python --framework --universal only builds a two-way binary...

Hey man.

Actually, at the time, I had compiled python with --with-universal-archs=3-way so it did work, but it was usless since it was a binary that relied on 10.6 resources.

I don't do that anymore though. Qt took about 9 hours to cross compile on an i7 :)

@brantfaircloth: I don't do 3way anymore, since the modules don't run on 10.5 anyway ;)

nobody does 3-ways any more, sadly... badum, bump! i'll be here all week.

Updated for brew.

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:
