[PyQt] How to build PyQt4 as 32/64-bit on a Mac

[Emanuele Santos]

Hi,

I've installed Qt 4.7.3 Cocoa 32/64-bit libs on a Snow Leopard machine
that has XCode 3.2.6 installed.
I am using python 2.7.2 32/64-bit from python.org

I am trying to build a 2-way (32-bit/64-bit) installation of PyQt4 but
the configure step fails.

I've built sip 4.12.4 without errors using the commands:

$ python configure.py --arch=i386 --arch=x86_64
$ make
$ make install

When I try to build PyQt4-mac-gpl-4.8.5 it fails testing all the other
modules (QtGui QtHelp etc), with an error similar to:

ld: framework not found QtGui
collect2: ld returned 1 exit status
ld: framework not found QtGui
collect2: ld returned 1 exit status
lipo: can't open input file:
/var/folders/h9/h9It34qgGYOcx12sG2ZPyk+++TM/-Tmp-//ccAzLAHL.out (No
such file or directory)

This is the output up to the first error:

$ python configure.py -w

If I build sip as 64-bit only, all PyQt's tests pass and all the
modules are built without problems.

Has anybody got PyQt to build it as 32-bit and 64-bit successfully on
a Mac without building Qt from source?

Thanks,
