I'm trying to compile against QT 5.8 and it doesn't seem to like the 5.6 version of the wrappers:
pythonqt_build_win32\pythonqtcode\generated_cpp_56\com_trolltech_qt_core_builtin\com_trolltech_qt_core_builtin0.h(1275) : error C2039: 'WindowOkButtonHint' : is not a member of 'Qt'

I thought I'd try to regenerate the generated_cpp directory but I can't seem to get it to work:
set QTDIR="C:\usr\tools\qt\5.8\msvc2013"
cd generator
pythonqt_generator.exe
This doesn't appear to find anything. I get the output below. I can't seem to find instructions for running pythonqt_generator.exe

Any instructions for re-running the generator?

I haven't tried Qt 5.8 yet. If the two enums are the only errors, it is easiest if you just remove them from the enum wrapper manually and rebuild.
Please tell me it works, I can remove the enums on svn trunk as well if it works, since they are for Windows CE only.
Regarding the wrappers, did you install Qt with full headers files? How did the last run end?
I will try running the generator myself tomorrow.

Looks like the C++ parser of PythonQt can only handle Qt up to 5.6.
Qt 5.7 starts using C++ 11 features, which the C++ parser of the PythonQt generator can not handle.
I inherited the C++ parser from QtJambi and QtScript wrappers several years ago.
I saw that the PySide guys are working on integrating clang as a C++ parser instead (they are using the same C++ parser as PythonQt does at the moment).
If they succeed (which I am quite sure), I will probably switch to the PySide APIExtractor
as well. Until then, we have to live with the Qt 5.6 wrappers and keep them compiling on Qt 5.7/5.8/...

Hi, I had the same issue, but in addition to modifying the WindowOkButtonHint and WindowCancelButtonHint I needed to do the following modifications:
In src\PythonQtConversion.cpp line 1507
Add missing ;
In src\PythonQtSlotDecorator.cpp line 45,
Add "const" to the declaration
and on line 47 in the same file do a typecast to (char * * ) for the kwlist argument.
After these modification compilation and examples worked fine.
I am using MSVC2015.
Is there a better way to get things working?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Looks like the PythonQt parser could not handle the QOpenGLFunctions since changes in Qt 5.7/5.8.
I ignored those files in the generator now and generation on Qt 5.8 seems to work again.
Anyways, in the long run I will need a C++ parser that can handle C++11 and I am probably following PySide in what they are going to use.

Dear Florian, dear all,
I'm using PythonQt very sucesfully for scripting purpose in my appplication. It is a really powerful tool and I really apreciate it a lot. I normaly work with Unix-like system, i.e. Linux and macos. On both systems I never had issues compiling PythonQt.
I'm now working to port my application (its, koil here on sourceforge) on windows....and I encounter a lot of issues in setting up the correct toolchain. I apologize if this could appear a stupid issue, but I'm stucking in trying to understand the correct step by step procedure to follow in order to have a fresh and running toolchain to compile qt based application using PythonQt under windows (on mac and linux no problem at all!).
When working on windows, I normally use mingw. I understood that this is not the designed way for PythonQt and I should move to MSVC compiler. Then I found some posts describing the necessity to re-compile both Python and qt with the same compiler version. Even if I try different combination I never reach a working solution.
Therefore, I kindly ask the comunity support in order to provide "step by step" instructions for newbie like me in windows compiling (including proper download links would be ideal) to install all the required toolchain (compiler, qt libraries, python itself, PythonQt,...). Mybe such request sounds "stupid" or trivial to some more expert users, bu I think such a "installation tutorial" would be very appreciated by many other people that is at the begining of apporaching PythonQt (at least on windows system).
Many thanks and regards
Luigi

Hi, Luigi!
To build PythonQt in Windows with mingw, do the following:
1) comment out these lines in C:\Qt\Tools\mingw492_32\i686-w64-mingw32\include\c++\cmath:
Great product PythonQT loving it, Has anyone having any success at building it from a Shadow Build Directory? Like from QtCreator. Examples don't expect the libs to be outside the Python directories proper, and link errors.

I removed the two enum items, apart from that the Qt 5.6 wrappers work fine with Qt 5.8.

The svn trunk of PythonQt already contains these changes, so if you check out the sources it should now compile out of the box with Qt 5.8

Hi, Luigi!
To build PythonQt in Windows with mingw, do the following:
1) comment out these lines in C:\Qt\Tools\mingw492_32\i686-w64-mingw32\include\c++\cmath:
//using ::hypot;
//using ::hypotf;
//using ::hypotl;
(see https://sourceforge.net/p/pythonqt/discussion/631392/thread/188d4e7c/#4818).
2) create environment variables
PYTHON_PATH = c:\Python27
PYTHON_LIB = c:\Python27\libs
3) in python.prf set python version:
win32:PYTHON_VERSION=27
unix:PYTHON_VERSION=2.7
and change the line (preffix "lib" and suffix "a")
win32:LIBS += $$(PYTHON_LIB)/libpython$${PYTHON_VERSION}$${DEBUG_EXT}.a
4) common.prf:
CONFIG += release
5) PythonQt_QtAll.prf (similarly libPythonQt_QtAll.a):
win32::LIBS += $$PWD/../lib/libPythonQt_QtAll$${DEBUG_EXT}.a
6) PythonQt.prf (libPythonQt.a):
win32::LIBS += $$PWD/../lib/libPythonQt$${DEBUG_EXT}.a
7) in src.pri comment out (or delete) the line:
win32:QMAKE_CXXFLAGS += /bigobj
8) in src\gui\PythonQtScriptingConsole.cpp, PythonQtScriptingConsole::executeCode:
toLatin1 replace to toUtf8
9 ) in src\PythonQt.cpp, PythonQt::evalScript:
toLatin1 replace to toUtf8
10) qmake
mingw32-make
Good luck!
Sergey.
Great product PythonQT loving it, Has anyone having any success at building it from a Shadow Build Directory? Like from QtCreator. Examples don't expect the libs to be outside the Python directories proper, and link errors.
