Now I have 6 files in package folder.
D:\BINDINGTEST\FOOLIBBINDING\PACKAGE
FooLib.dll
foolib.pyd
foolib_test.py
libshiboken-python2.7.dll
QtCore.pyd
QtCore4.dll
1. Run foolib_test.py with QtCore4.dll copied from PySide 1.1.2 folder. I
got below error.
D:\BindingTest\FooLibBinding>foolib_test.py
Traceback (most recent call last):
File "D:\BindingTest\FooLibBinding\foolib_test.py", line 1, in <module>
from foolib import FooClass
ImportError: No module named foolib
2. Copied D:\Qt\4.8.1\bin\QtCore4.dll from my Qt 4.8.1 installation to
D:\BINDINGTEST\FOOLIBBINDING\PACKAGE. Run foolib_test.py again, I got below
error.
D:\BindingTest\FooLibBinding\package>foolib_test.py
ImportError: could not import module 'PySide.QtCore'
Fatal Python error: can't initialize module foolib
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
Could you help to have a check the cause of the error message?

Hi,

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
I will try to generate the .a version of shiboken-python2.7.lib so the next
version of PySide package will contain both .lib and .a versions.
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?
You can try to replace Qt DLLs from PySide with version you have installed in
system. I will try to regenerate the binding test with mingw...
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
2013/1/15 Roman Lacko <[email protected]<mailto:[email protected]>>
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.
