Qt項目突然停止建設。所以剛剛創建了基於QDialog或實例的空項目。清潔,重建沒有幫助。Qt標準項目和示例停止建設
關鍵的錯誤日誌:

好像發生了什麼事情與qdialog.h什麼的。順便說一下QMainWindow上的項目工作正常。我什麼也沒做。試圖重新打開QtCreator,重新啓動計算機。 我使用Mac OS X和Qt 5.2.1
QtCreator提供的任何示例或基於QDialog的空項目。例如: dialog.cpp:
#include "dialog.h"
Dialog::Dialog(QWidget *parent) :
QDialog(parent)
{
}
Dialog::~Dialog()
{
}
dialog.h
#ifndef DIALOG_H
#define DIALOG_H
#include <QDialog>
class Dialog : public QDialog
{
Q_OBJECT
public:
explicit Dialog(QWidget *parent = 0);
~Dialog();
};
#endif // DIALOG_H
的main.cpp
#include "dialog.h"
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Dialog w;
w.show();
return a.exec();
}

它是Qt本身還是Qt之上的一些示例項目?如果是後者,你能否顯示你的代碼? – lpapp
