我正在使用CodeBlocks。這是該項目，如果需要的話：http://i.imgur.com/Wz8Bya9.png未定義引用`_imp___ZN12QApplicationC1ERiPPci'
我是一個非常非常早期的C++初學者，我一直在爲RPG遊戲（TTU參考）代碼嘗試修復並運行它的啓動程序。我遇到了一堆我很容易修復的錯誤，但是我遇到了這個障礙，我不確定問題在哪裏。我想我必須在項目設置中添加來自Qt的庫？但我不知道我會找到這些庫文件，哪些鏈接，等等。這是文件（核心\ main.cpp中），這是獲得這些錯誤：
#include "ui\LauncherWindow.h"
#include <QtWidgets\QApplication>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
LauncherWindow *launcher_window = new LauncherWindow;
launcher_window->show();
return app.exec();
}
而且我越來越這些錯誤：

所以有人可以解釋究竟是什麼問題，以及如何解決它？非常感謝你提前。 -Intoxadox :)
你需要鏈接到Qt。 –
