[PyQt] Re: py2app generates huge files (200MB)

[Michael Held]

hi piotr,

yes, it looks like PyQt4 is using a lot of Pythons standard packages, so
all the files in Contents/Resources/lib/python2.6/lib-dynload are most
probably needed...

I zipped and got 70MB with Qt debug files (from 200MB)
and 15MB without (from 43MB).
is there a way to provide an .app file with zipped content which is
unzipped on the fly?

currently there is not installer for PyQt4.5 on MacOS available, right?!
I was compiling everything from scratch (I am also working with
Stackless Python 2.6.2). I guess there is a way to compile PyQt4 in
universal mode... somehow ;-)

thanks a lot again! :-)
cheers
michael
