我目前正在尝试在Qt上为我在visual studio上编写的程序创建一个GUI。在vs中,运行代码时没有问题。
我创建了一个在Qt中运行良好的窗口,然后我决定只从visual studio中添加一个类。我在项目中添加了它们并进行了编译。编译期间没有错误。但是当我尝试运行程序时,它会在显示之前崩溃,并显示以下消息:"程序意外完成。"即使我实际上并没有从该课程中调用任何方法。
似乎如果我取出使用ifstream文件的代码的所有部分,它就不会崩溃。
以下是该类的完整cpp代码:

正如我所说,如果我取出使用ifstream的函数,它会正确运行。如果我不这样做,它会编译,但会在执行时崩溃。
如果你找到任何答案,非常感谢你的答案!
答案 0 :(得分:0)
我发现了我的问题,即使并且没有看到它与ifstream的关系。我需要在目录中添加openCV的.dll文件,我忘了把它们放回去。因此它编译了,但在Startup崩溃了。希望这有帮助! 无论如何,谢谢你的帮助:)。
