我有一个使用Qt框架开发的桌面应用程序。在OSX上的向后兼容性方面，我有一个问题：该应用程序在10.15上编译，在10.15和10.14上运行良好。该二进制文件也以10.13启动，但在某个时刻引发了关于libSystem.B.dylib:中丢失符号(__chkstk_darwin(的错误

有人能向我解释一下如何处理这个问题吗？
提前感谢，最佳

QMAKE_MACOSX_DEPLOYMENT_TARGET=10.13必须是PRO文件的一部分。事实已经是这样了，这就是我感到困惑的原因。最终，我们可以得出结论，涉及到一个额外的lib，它不是为10.13编译的，并导致了实际问题。在编译10.13并使用此库后，问题得到了解决。
