I am using Debian 9, python 3.7.3 and cx_Freeze 6.0b1. I spent some time installing cx_Freeze on Windows 7 and Debian, I managed to compile the script on both platforms.

When I share it, the Windows version runs, but the Linux version raises an error about missing dependencies. The app is still looking for the files in the absolute path, and I don't understand why.

When I run cx_Freeze, the .so file are copied to the output directory.

My compiled program:

import numpy as np
import matplotlib.pyplot as plt

f=open('hello.txt','w')
f.write('Hello World')
f.close()

y=lambda x:np.sqrt(x)
x=range(10)
plt.plot(x,y(x))
plt.show()

My setup.py program:

from cx_Freeze import setup, Executable
exclude = []
executables = [
Executable('hello.py', base=None, targetName='Hello')]
includes=["encodings"]

include_files=[]
includes=[]
packages=["numpy","matplotlib"]

setup(
name = "Hello",
version = "1 ",
description = "Hello World",
options = {'build_exe':{"packages":packages, "include_files":include_files,'excludes':exclude,'includes':includes}},
executables = executables
)

Error while trying to execute the app on a second computer:

Traceback (most recent call last):

Try to manually copy all the lib*.so.* files into the lib subdirectory of the frozen application before sharing. Does this solve your problem? If yes, you could automatize this step using shutil.copy2 at the end of your setup.py script for example.

Regarding your comment:

The app is still looking for the files in the absolute path, and I don't understand why

I guess you refer to the paths appearing in the tracebacks. These are filenames attached to code objects which presumably do not get actualized when the frozen application is moved. You can let cx_Freeze replace these absolute paths through relative ones by adding an entry

'replace_paths': [("*", "")]

to the build_exe option dictionary in the setup.py script. See issue #247 on the cx_Freeze repository and the links therein.

  • It doesn't work. I copy every `.so` file to the root and lib folder, and it raises the same error – ansarto Jun 17 '19 at 07:03
  • @ansarto Which version of numpy are you using? – jpeg Jun 17 '19 at 08:46
  • it is numpy 1.16.2. I try with the 1.16.3, like my windows installation. It works on some computers, but raise other errors I still have the `libffi.so.6` file from numpy missing, and sometime some matplotlib files. – ansarto Jun 19 '19 at 06:27
