MSVC2013 ile 'QJsonObject :: yineleyici' kullanmaya çalışırken garip bir hata yaşıyorum.hata: C2039: 'işaretçisi': 'QJsonObject :: yineleyici' bir üyesi değil
Bu kod derler ve MSVC2008 ile beklendiği gibi çalışır#include <QCoreApplication>
#include <QJsonObject>
#include <QDebug>
#include <algorithm>
void processValue(QJsonValue value) {
qDebug() << value.toString();
}
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
QJsonObject jsonObject;
jsonObject.insert("a", "A");
jsonObject.insert("b", "B");
jsonObject.insert("c", "C");
jsonObject.insert("d", "D");
jsonObject.insert("e", "E");
std::for_each (jsonObject.begin(), jsonObject.end(), processValue);
return a.exec();
}
ve MinGW (WinCE çapraz derleme), ancak MSVC2013 ile:
Ben şu örneği var. Her durumda, Qt 5.5.1 kullanıyorum.

Sadece 2 diğer derleyicilerde tesadüfen çalışmak olur Burada yanlış bir şey yapıyor muyum?
