[PySide] Simple shiboken binding tutorial -- was PySide - Qt5 - Swig

[ZHONG Zhu]

Thank you Roman, I completed all steps except for step 5.

1.       Some problem found. In step 3, in FooLibBinding\FooLibBinding.pro,  I should be using shiboken-python2.7.a but PySide Windows installer only installed shiboken-python2.7.lib. So I have to use MinGW to build Shiboken from source to get both libshiboken-python2.7.dll.a and libshiboken-python2.7.dll

2.       After the "package" been generated, I tried to run foolib_test.py but failed.  Error message is like below. Then I used "Dependency Walker" to load foolib.pyd. It complains about QtCore4.dll. Error message is "Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module." I checked and looks like QtCore4.dll shipped with PySide installer is based on Qt 4.8.2 but my local Qt C++ installation is Qt 4.8.1. Could this be the reason I can't run foolib_test.py? Do I need to upgrade my Qt SDK to higher version like 4.8.4?


D:\BindingTest\FooLibBinding\package>foolib_test.py
Traceback (most recent call last):
  File "D:\BindingTest\FooLibBinding\package\foolib_test.py", line 1, in <module>
    from foolib import FooClass
ImportError: DLL load failed: The specified procedure could not be found.
===============================
1. Install PySide
2. Copy content of c:\Python27\Lib\site-packages\PySide to BindingTest\PySide folder
1. Compile FooLib project
2. Run FooLib\generate_binding.bat
3. Compile FooLibBinding project
4. Run FooLibBinding\make_package.bat
5. Go to generated folder "package" and run foolib_test.py

sorri, you also have to update the path where you have installed Qt on your system in files:

pyside\include\PySide\pyside_global.h
FooLib\generate_binding.bat

...replace this "c:\Qt\qt-4.8.4-msvc2010-x64" with your path

btw, you need to update paths to python libs and includes in FooLibBinding\FooLibBinding.pro. I have installed python in c:\Python27_64.
Also if you are using mingw, you will need to change the .lib extension to .a

INCLUDEPATH += ../pyside/include/PySide \
    ../pyside/include/PySide/QtCore \
    ../pyside/include/shiboken \
    c:/Python27_64/include \
    ../FooLib

LIBS += c:/Python27_64/libs/python27.lib \
    ../pyside/shiboken-python2.7.lib \
    ../FooLib-build-Desktop-Release/release/FooLib.lib

Hi,
i have prepared the sample projects for you here [1]
Description:

This is sample demonstration how to generate simple bindings with shiboken python binding generator

FooLib project contains the library for which we want to generate the bindings
FooLibBinding project contains the generated binding sources

Software used:

Qt 4.8.4 MSVC 2010 64bit
Python 2.7 64bit
PySide 1.1.2 for Python 2.7 64bit

To generate and test the bindigs do the following:

1. Install PySide
2. Copy content of c:\Python27\Lib\site-packages\PySide to BindingTest\PySide folder
1. Compile FooLib project
2. Run FooLib\generate_binding.bat
3. Compile FooLibBinding project
4. Run FooLibBinding\make_package.bat
5. Go to generated folder "package" and run foolib_test.py

Thank you for your kindly reply!
I was following this tutorial but just can't build a working binding on Windows.
Do you have any experience on building the binding on Windows?

I have used this tutorial to create my first bindings: http://qt-project.org/wiki/PySide_Binding_Generation_Tutorial. it contains downloadable package with full source.
regards
R.
