[PyQt] SIP with PyQt5 and "A More Complex C++ Example"

[bitmap kid]

Maybe, the complete history of my commands will help you:



[th at mecanic ~/sip] ls
hello.cpp  hello.h  hello.sip  main.cpp
[th at mecanic ~/sip] sip -t WS_X11 -I /usr/share/sip/PyQt5 -c . hello.sip
[th at mecanic ~/sip]  /usr/bin/g++  -DDEBUG -DHOST -DQT_CORE_LIB -DQT_GUI_LIB
-Dserver_EXPORTS -I. -I../ -Iserver_autogen/include -I../.
-I/usr/include/python3.7m  -isystem /usr/include/qt -isystem
/usr/include/qt/QtCore -isystem /usr/lib/qt/mkspecs/linux-g++ -g -fPIC
-Wall -pedantic -fPIC -std=gnu++17 -MD -I /usr/include/qt/QtWidgets/ -I

./siphellocmodule.cpp: Dans la fonction « PyObject*
func_setDefault(PyObject*, PyObject*) »:
./siphellocmodule.cpp:438:13: error: « setDefault » n'a pas été déclaré
dans cette portée
             setDefault(*a0);
             ^~~~~~~~~~
./siphellocmodule.cpp:438:13: note: alternatives suggérées:
« func_setDefault »
             setDefault(*a0);
             ^~~~~~~~~~
             func_setDefault
