Python bindings build fails on KDE Neon 5.21.5 #197

Closed mara004 closed 3 years ago

mara004 commented 3 years ago

Hello,

I attempted to build/install the Python/PySide2 bindings for KDDockWidgets (Release 1.3.0) on KDE Neon 5.21.5 with Qt 5.15.2, but apparently shiboken failed while loding some shared library.

Here is the log:

Thanks for your help.

I don't have a solution inside kddockwidgets itself at the moment. it feels like a problem in QtForPython

for now you can try: export LD_LIBRARY_PATH=/usr/local/lib/python3.8/dist-packages/PySide2/Qt/lib

This made shiboken work, but now there's a new problem with the clang include directory:

Ah, I have been able to fix it by simply installing the llvm package ;).

Now KDDockWidgets is installed to /usr/local/KDAB/KDDockWidgets-1.3.0/ and PyKDDockWidgets to usr/lib/python3.8/site-packages/PyKDDockWidgets/, but running the Python example fails:

me@lx2020:~/Downloads/builds/KDDockWidgets-1.3.0/python/examples$ python3 main.py 
Traceback (most recent call last):
  File "main.py", line 12, in <module>
    from PyKDDockWidgets import KDDockWidgets
ImportError: libkddockwidgets.so.1.3: cannot open shared object file: No such file or directory

I already tried to set PYTHONPATH but it didn't help.

Make sure that the path that contains libkddockwidgets.so is part of your LD_LiBRARY_PATH

Ah, right. Thanks!
