ImportError: libjpeg.so.9: cannot open shared object file: No such file or directory

After running install script, I get the following error:

# ./openplc_editor.sh
Traceback (most recent call last):

sudo nano install.sh # Replace all instances of "python3.8" with "python3" in the install.sh script ./install.sh # No error messages this time ./openplc_editor.sh # Returns the error about libjpeg.so.9

I checked and libjpeg-dev is installed on my system. But also ran sudo apt install libjpeg-dev just in case. Any ideas on this?

Installer should take care of all dependencies. You don't have to install wxPython, lxml, etc on your system python as it is not being used. OpenPLC creates a virtual environment using venv for its own dependencies. Most likely this libjpeg.so.9 issue is a wxPython dependency that didn't get sorted out during the build process. Try changing python3.8 with python3.9 on the installer script. I know that wxPython has problems building on python 3.10 and up, that's why I included python3.8 on the script, but apparently your system does not offer support for python 3.8 anymore.

I just updated the install script to use python 3.9. Clone the repo and try again.

Deleted the downloaded repo folder, cloned again, ran ./install.sh with the following result:

I don’t know where this libjpeg.so.9 is coming from. I tested on other Ubuntu based systems and it worked just fine. I’m wondering if the issue is related to a precompiled wxPython who for your system. Try to force pip to recompile wxPython instead of using a precompiled binary with --no-cache-dir --no-binary :all:
