I'm trying to compile some Python 3.3 code using cx_freeze and, after compiling, the resulting test.exe file will create an indefinite number of instances of the program, causing my Windows 7 system to become unstable. It works just as intended when just running in Python, but once compiled it causes issues. Here are my imports in my main script:
import sys
from multiprocessing import Pool, Queue
from threading import Thread
from time import sleep, time
from inspect import getmembers
from PyQt5 import QtWidgets, QtCore, QtGui
from main_ui import Ui_MainWindow # Generated UI from pyuic, imports
# QtWidgets, QtCore, and QtGui
from devices import Device1, Device2 # Both are serial.Serial objects
The setup.py script:
import sys
from cx_Freeze import setup, Executable
product_name = 'Product Name'
path_platforms = ("C:\Python33\Lib\site-packages\PyQt5\plugins\platforms\qwindows.dll",
"platforms\qwindows.dll")
includes = ['PyQt5.QtWidgets', 'PyQt5.QtCore', 'PyQt5.QtGui']
include_files = [path_platforms]
excludes = ['_gtkagg', '_tkagg', 'bsddb', 'curses', 'email', 'pywin.debugger',
'pywin.debugger.dbgcon', 'pywin.dialogs', 'tcl',
'Tkconstants', 'Tkinter']
packages = ['os']
path = []
bdist_msi_options = {'add_to_path': False}
build_exe_options = {'includes': includes,
'include_files': include_files,
'excludes': excludes,
'packages': packages,
'path': path,
'silent': True}
base = None
if sys.platform == 'win32':
base = 'Win32GUI'
exe = Executable(script='main.pyw',
base=base,
targetName='test.exe')
setup(name=product_name,
version='1.0',
description='The Test Program',
executables=[exe],
options = {'bdist_msi': bdist_msi_options, 'build_exe': build_exe_options})
And when I run python setup.py build, the following error occurs:
Missing modules:
? System imported from serial.serialcli
? TERMIOS imported from serial.serialposix
? __main__ imported from bdb
? _gestalt imported from platform
? _posixsubprocess imported from subprocess
? clr imported from serial.serialcli
Despite these errors, it still generates a test.exe file. When I execute it, it generates a seemingly infinite number of windows and the only way to stop it is to hard reset the computer. Again, the main script works just fine running under Python, but fails once compiled. Any help would be greatly appreciated!
