如何解决丢失的符号：__chkstd_darwin in libSystem.B.dylib (OSX)
how to resolve missing symbol: __chkstd_darwin in libSystem.B.dylib (OSX)
我有一个使用 Qt 框架开发的桌面应用程序。关于 OSX 的向后兼容性，我有一个问题：该应用程序是在 10.15 上编译的，在 10.15 和 10.14 上运行良好。该二进制文件也随 10.13 一起启动，但有时会抛出有关 libSystem.B.dylib:

QMAKE_MACOSX_DEPLOYMENT_TARGET=10.13 必须是 PRO-File 的一部分。情况已经如此，这就是我感到困惑的原因。最终我们可以确定涉及一个额外的库，它不是为 10.13 编译的，并导致了实际问题。为 10.13 编译并使用这个库后，问题就解决了。
