C++ Qt库shiboken绑定pyd无法导入

Question

I'm trying to build the example widgetbinding from pyside's examples. I successfully built the module pyd but I cannot import the module after I built the pyd . I also tried my own C++ Qt library and got the same error.

I use cmake to build the binding module:

cmake -B ./build -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release
cd build
nmake
nmake install
cd .. # back to the directory my pyd installed
ipython # start testing the importing

In [1]: import wiggly
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-8a2812855881> in <module>
----> 1 import wiggly

ImportError: DLL load failed while importing wiggly: 找不到指定的模块。

trying to include the module in python

I'm on Windows 10 and using Qt 6.0.2, Shiboken6.0.1 and PySide6.0.1. The python on my machine is download directory from python.org.(Does it matters that I'm not using a python built on vs2019 on my own?)

I can successfully build the samplebinding from pyside6/examples, which doesn't contain any Qt related C++ code. Able to import the module in python

Answer 1

I've found the solution.

I got this ImportError because I'm testing the pyd on IPython using one single line:

import wiggly

but the pyd in this case(built as a Qt library) have dependencies on dlls like pyside6.abi3.dll , QtWidgets.dll , etc.

So when I import PySide6.Qwidgets before importing wiggly, It works: Now I write:

import PySide6.QtWidget
import wiggly
