问题描述
我已经实现了一个 C++ 异常并在错误时抛出这个异常而没有捕获它.在 linux 中，我确实在控制台上看到了异常文本(what")并且应用程序存在.这是我预期的行为.
I've implemented a C++ Exception and throw this exception on errors without catching it.In linux I do see the exception text ("what") on console and the application exists. This is my expected behaviour.
在 Windows(使用 Visual C++ 2015 编译)上，但是会打开一个弹出窗口并指出一般错误.我在控制台或其他任何地方都没有看到异常消息.是否也可以在 Windows 上将抛出/未捕获的异常记录到控制台/标准输出(或标准错误)?
On windows (compiled with Visual C++ 2015) however a popup window opens and states a generic error. I do not see the exception message on console or anywhere else. Is it possible to log thrown/uncaught exceptions to console/stdout (or stderr) on Windows, too?
谢谢
推荐答案
抛出未捕获的异常会终止您的程序.无论如何，您的 Linux 工具链都非常友好地显示了消息；当然不需要这样做.此终止计为崩溃，因此会出现弹出窗口.
Throwing an uncaught exception terminates your program. Your Linux toolchain is being very kind by showing the message anyway; it's certainly not required to do so. This termination counts as a crash, hence the popup window.
在 main 中放置一个 try/catch 对，以安全地捕获所有其他未处理的异常.不过，这不会帮助您构建全局变量.
Put a try/catch pair in main to safely catch all otherwise-unhandled exceptions. This won't help you with construction of your globals, though.
