Good
I specify in form.cpp:
#include "form1.h" #include <QJsonDocument> An error is displayed:
form1.cpp: ошибка: QJsonDocument: No such file or directory #include <QJsonDocument> ^~~~~~~~~~~~~~~ OS: Ubuntu 18.4 The / usr / include / x86_64-linux-gnu / qt5 / QtCore files are:
root@pavelpc:/usr/include/x86_64-linux-gnu/qt5/QtCore# ls *json* qjsonarray.h qjsondocument.h qjsonobject.h qjsonvalue.h What am I doing wrong?
