I am trying to freeze an app on Ubuntu 14.10. The app uses PyQt5 and runs
under Python3.4
Cxfreeze creates a bundle into which it copies all the dependent libraries,
for example libQt5Core.so.5, libQt5Widgets.so.5, and so forth. It also
copies the PyQt libs such as PyQt5.QtCore.so, PyQt5.QtWidgets.so, etc.
When I move this bundle to another Ubuntu system where this version of
Python and Qt are not installed, is I get the dreaded message,
Cannot mix incompatible Qt library (version 0x50300) with this library
> (version 0x50401)
> Aborted (core dumped)
>
I think it is trying to load from the local Qt (Ubuntu has some version of
Qt installed by default). On that system, after copying the bundle from the
dev system, I see this:
$ cd Desktop/PPQT2 # the bundle made by cxfreeze
>
$ ldd libQt5Widgets.so.5
> linux-gate.so.1 => (0xb779c000)
> libQt5Gui.so.5 => /home/dcortesi/Desktop/PPQT2/./libQt5Gui.so.5
> (0xb6b49000)
> libQt5Core.so.5 => /home/dcortesi/Desktop/PPQT2/./libQt5Core.so.5
> (0xb6605000)
...

That is good! libQt5Widgets is linking to the bundled copy of libQt5Gui and
so on.
However:
$ ldd PyQt5.QtWidgets.so
> linux-gate.so.1 => (0xb7776000)
> libQt5Widgets.so.5 => /usr/lib/i386-linux-gnu/libQt5Widgets.so.5
> (0xb6afb000)
>
That is bad, PyQt5.QtWidgets is linking to the local native libQt5Widgets
-- NOT the one bundled right there alongside it.
Why is this? Am I doing something wrong? Or is something needed in the
hooks for PyQt5?
Thanks for any help,
Dave Cortesi
