我在Xcode中用c ++编写了一个控制台应用程序。当通过finder启动时（通过双击build目录中的可执行文件），我得到一个终端窗口，上面写着“Segmentation fault：11”。
但是，当我打开终端时，导航到该文件夹并通过执行./“可执行文件名”运行可执行文件“程序运行正常。在终端中的lldb实例中启动时也可以正常运行。
为什么会这样？
从控制台到应用程序的崩溃日志。下面：

事实证明，当通过Finder启动程序时，它的工作目录设置为＆＃39; /＆＃39;而不是从中启动可执行文件的目录。这导致程序中的段错误，因为我试图在可执行文件的相对位置加载库。我仍然需要弄清楚如何做到这一点，但至少现在知道错误的原因。
感谢有关日志记录和验证的建议，通过这些建议，我能够弄清楚发生了什么。
