Custom QWidget Shiboken Binding is Failing to build

      When porting my first Qt4 module to Qt5, I am able to run the Shiboken2 binding generator, however the resulting binding does not compile due to the following error:

      qprogressindicator/qprogressindicator_wrapper.cpp:2126:5: error: no member named 'Signal' in namespace 'PySide'; did you mean 'sigval'?
          PySide::Signal::registerSignals(Sbk_QProgressIndicator_TypeF(), &::QProgressIndicator::staticMetaObject);
      /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/sys/signal.h:158:7: note: 'sigval' declared here
      union sigval {
      qprogressindicator/qprogressindicator_wrapper.cpp:2126:21: error: no member named 'registerSignals' in 'sigval'
          PySide::Signal::registerSignals(Sbk_QProgressIndicator_TypeF(), &::QProgressIndicator::staticMetaObject);

      It appears that a call to PySide::Signal::registerSignals() inside qprogressindicator_wrapper.cpp is unable to access the "Signal" namespace inside the "PySide" namespace.

      I found the declaration of* *registerSignals() inside SITE_PACKAGES/PySide2/include/

      pysidesignal.h. I tried to include it inside my bindings.h file, but it didn't help. I can see that there is a PySide::Signal::*registerSignals() function inside this file, but I can't seem to call it.*

      When I comment out the* PySide::Signal::registerSignals() call inside qprogressindicator_wrapper.cpp the Widget is able to run inside Python as expected, but I have no idea what I just commented out.*

      I have this problem on mac OS 10.13 and Windows 10.  My C++ project is attached and can be built as follows:

      >>>cd QProgressIndicator/
      >>>cd src/
      >>>make install
      >>>cd ..
      >>>cd shiboken
      >>>make  *(Failure occurs Here)*
      >>>make install
      >>>cd ..
      >>>python main.py


      • root.pri: qmake pro file that is common to all my projects
      • QProgressIndicator.zip: A QWidget that is failing when compiling the python binding
      • universe.zip: The PySide2/example/samplebinding project with qmake instead of cmake. It works correctly but does not use any Qt libraries.
