问题
I'm trying to use cx_freeze 4.3.3 on a MacOS running 10.9.2 on a very simple PyQt5 script with Python 3.3.
No errors are returned and the .app is output. However when running the .app from terminal I obtain the error:
LSOpenURLsWithRole() failed with error -10810
which according to Apple's documentation is "Unknown Error".
The very simple code I try to run (PyQt5app.py) is:
import sys
from PyQt5.QtWidgets import QApplication, QDialog
app = QApplication(sys.argv)
form = QDialog()
form.show()
app.exec_()
The file setup.py is:
import sys
from cx_Freeze import setup, Executable
base = None
if sys.platform == 'win32':
base = 'Win32GUI'
options = {
'build_exe': {
'excludes': ['Tkinter'] # Sometimes a little finetuning is needed
}
}
executables = [
Executable('PyQt5app.py', base=base)
]
setup(name='PyQt5app',
version='0.1',
description='Sample PyQt5 GUI',
executables=executables,
options=options
)
and when running I call:
sudo python cx_freeze bdist_mac
obtaining this log : http://pastebin.com/VBxyyBRn
with app returning error above.
So, reading around I see it might be a problem related to including qt files in the app (or at least this was the issue on PyQt4) so I try specifying the qt-menu-nib directory:
sudo python setup.py bdist_mac --qt-menu-nib=/Users/franco/Qt5.2.1/5.2.1/clang_64/plugins/platforms/
obtaining this log: http://pastebin.com/TpRdrSmT
and the same not working error.
If I run the app from PyQt5app.app/Contents/MacOS/PyQt5app I get a lot of bootstrap errors:

Needless to say the script works fine when launching from terminal:
python PyQt5app.py
I most certainly am doing something wrong, so please, can anybody help me?

So, after long fighting here is the issue: libzmq . I installed libzmq and specified the --qt-menu-nib option and the simple example above runs in both:
sudo python setup.py build
and
sudo python setup.py bdist_mac
Step by step instructions:
I used mac ports for most of my python33 packages so I sticked to it for the rest. Libzmq is not available on macports but its dependencies are. So:
1) install libtool, autoconf, automake:
sudo port install libtool
sudo port install autoconf
sudo port install automake
2) grab the latest version of libzmq from https://github.com/zeromq/libzmq ( I downloaded the ZIP for sake of order ) and unzip/navigate to the folder
/libzmq-master
now the instructions provided in the INSTALL document in the folder are pretty clear, if you installed all the dependencies then you will be fine. run:
sudo ./autogen.sh
sudo ./configure
sudo make
sudo make install
3) download the latest cx_freeze from https://bitbucket.org/anthony_tuininga/cx_freeze/downloads then unzip/untar navigate to folder and run:
sudo python setup.py build
sudo python setup.py install
now when compiling code for MacOSX that uses Python3.3 and PyQt5 you can run:
sudo python setup.py build
then navigate in the build folder and run the program as:
./nameoftheprogram
once you made sure this work then build the app or dmg (as you prefer) with:
sudo python setup.py bdist_mac --qt-menu-nib=/Users/username/Qt5.2.1/5.2.1/clang_64/plugins/platforms/
where the path is the path to your Qt5 installation. If I don't use the --qt-menu-nib option the app crashes on startup whereas the build works fine.
Hope this will help someone in the future.

I got the same error and recompiling with the latest version of ZMQ (4.0.4) did not solve the issue.
However, by looking in the messages of the /Applications/Utilities/Console.app program, I could see that an extra command line option was given to my Python program. This command line option always started with -psn_0_ followed by a number. Apparently psn stands for Process Serial Number (see: http://hintsforums.macworld.com/showthread.php?t=11978).
My program uses the argparse package to parse the command line arguments and exited with an error because it didn't recognized the -psn option. I now filter it out before parsing with argparse and this solved my problem.
