Generate binary file with pyinstaller

[Xav12358]

Hello,

I try to generate a binary file with pyinstaller. I have a program using PySide2.
I generate my binary with

pyinstaller  --onefile main.py -y

When I run the generated binary file, I get that error:

Traceback (most recent call last):
  File "main.py", line 4, in <module>
    from PySide2.QtWidgets import QApplication, QMainWindow
ImportError: /tmp/_MEIA5cWN3/libQt5Widgets.so.5: undefined symbol: _ZN9QFileInfo4statEv, version Qt_5
[67652] Failed to execute script 'main' due to unhandled exception!

@SGaist I have the same trouble.

According to that documentation, pyinstaller use the system environment to build the binary file:
https://doc.qt.io/qtforpython-5/deployment-pyinstaller.html

So if I use Conda, Virtual Env, it will alway use the systm environment to generate the binary.

Hi,

How did you install PySide2 ?
Are you sure pyinstaller is using the correct Qt version to create the package ?

[Xav12358]

@SGaist I use pip to install Pyside2.

How could I specify the version of Qt on pyinstaller?

The command I used is the one in the first post.

[SGaist]

Did you create a virtual environment ?

[Xav12358]

@SGaist no I use my system environment

[SGaist]

I would rather do that in a dedicated environment to keep everything cleanly separated.

[Xav12358]

@SGaist I generate a virtuel environment

I still use that command to generate the installer:

pyinstaller  --onefile main.py -y

I get that error when I run ./dist/main

Traceback (most recent call last):
  File "main.py", line 4, in <module>
    from PySide2.QtWidgets import QApplication, QMainWindow
ImportError: could not import module 'PySide2.QtGui'

In fact, I think I find the trouble. I include matplotlib and Pyside2

One is Using Qt5.15.0 and the other Qt5.15.2.

How can I manage to use Matplotlib and PySide2 with the same Qt library version?

How can I know with Qt version matplotlib use and also Pyside. I would like to specify the version of both library to avoid the trouble

[SGaist]

How did you install matplotlib ?

[Xav12358]

@SGaist I also use pip

[SGaist]

Can you try with conda ? If memory serves well, they should pull the same Qt version in.

Then clean your system Python and work exclusively from the virtual environment.

@SGaist I clean it and I looked at the python package version. I notice that the PySide version installed was the 5.15.2 and the matplot uses the 5.15.0. I modify the PySide versin and now the package are compatible.
