Hello, I'm creating an application using Qt (4.4 Beta atm). I have pretty close to zero experience with Python (consisting of installing the Python interpreter, downloading a python programming and executing it on the command-line).
I would like to invoke a Python script from my C++ Qt program and capture its output as a C++ structure. It seems that PythonQt might be suitable for my needs. Being a Qt program, I want this thing to be cross-platform. I'm having trouble getting things set up in Windows. Has anyone had any experience with this? I've built Qt from source using the mingw32 compiler. I installed Python 2.5 binary. I am trying to build PythonQt from source. As per http://pythonqt.sourceforge.net/#Building it says I need a "developer installation" of Python containing the header files and the library files. When I look at my system after installing the Python 2.5 binary, I can see I have header files (C:\Python25\include), a 199k python25.lib (C:\Python25\libs) and a 2MB python25.dll (C:\Windows\System32\). Have I got what I need? I have tried to set up my symbols (PYTHON_PATH, PYTHON_LIB, PYTHONQT_ROOT). I generate the Makefile (using qmake) and it starts to build but then it fails: g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -mthreads -Wl -shared -Wl,--out-implib,lib\libPythonQt.a -o lib\PythonQt.dll object_script.PythonQt.Debug -L"c:\Qt\4.4.0-beta1\lib" "c:\Python25\libs"/python25.lib -lQtGuid4 -lQtCored4 ./debug\PythonQt.o: In function `ZN8PythonQtC2Ei': C:/PythonQt-1.0/src/PythonQt.cpp:118: undefined reference to `_imp__Py_NoSiteFlag' ./debug\PythonQt.o: In function `ZN8PythonQtC1Ei': C:/PythonQt-1.0/src/PythonQt.cpp:118: undefined reference to `_imp__Py_NoSiteFlag' ./debug\PythonQt.o: In function `ZN15PythonQtPrivate11wrapQObjectEP7QObject': C:/PythonQt-1.0/src/PythonQt.cpp:256: undefined reference to `_imp___Py_NoneStruct' C:/PythonQt-1.0/src/PythonQt.cpp:257: undefined reference to `_imp___Py_NoneStruct' ./debug\PythonQt.o: In function `ZN15PythonQtPrivate7wrapPtrEPvRK10QByteArray': C:/PythonQt-1.0/src/PythonQt.cpp:281: undefined reference to `_imp___Py_NoneStruct' C:/PythonQt-1.0/src/PythonQt.cpp:282: undefined reference to `_imp___Py_NoneStruct' ./debug\PythonQt.o: In function `ZN8PythonQt13introspectionEP7_objectRK7QStringNS_10ObjectTypeE': C:/PythonQt-1.0/src/PythonQt.cpp:620: undefined reference to `_imp__PyClass_Type' C:/PythonQt-1.0/src/PythonQt.cpp:625: undefined reference to `_imp__PyClass_Type' C:/PythonQt-1.0/src/PythonQt.cpp:625: undefined reference to `_imp__PyCFunction_Type' ... Since I'm new to compiling Qt with mingw and completely new to python, I was hoping for tips on why I'm getting these errors. If anyone has a better suggestion for a forum/mailing list then please let me know. Thanks, Jeff -- http://mail.python.org/mailman/listinfo/python-list
