When making Qt 32 bit builds on snow leopard, you probably also want to set this environment variable:


Note that if you want to build python 3.x 64 bit on Snow Leopard, your best bet is downloading the source and making the framework build.

There is a pretty detailed conversation here:

I used the system python that comes with snow-leopard, it is 64-bit.

 if you need to build all in 32 bit mode, you can use your already installed Qt (don't need the cocoa version)
and use to build sip an pyqt :


python2.6 configure.py -d /Library/Python/2.6/site-packages -b /usr/local/bin \
-e /usr/local/include -v /usr/local/share/sip --arch=i386


python2.6 configure.py -d /Library/Python/2.6/site-packages -b /usr/local/bin --use-arch i386

This assumes a 64-bit python-3 installation. How was python installed?
My understanding is that the universal Mac binaries provided at
python.org<http://python.org/> do not include support for x86_64.
