Golang链接过程中提示如下警告信息：

解决
首先，我们知道一个程序如果想要编译成可执行文件需要四个步骤：预处理、编译、汇编和链接。
一个编译器的工作流程一般会包括以下几个步骤，请看图：
接下来，我们开始分析上述问题的原因。根据系统提示的信息，我们知道中间文件 *.o 文件编译时是为 mac OS 10.15 系统编译的，但是链接的时候却是为 mac OS 10.14 系统链接的，前后存在不一致的情况，因此发出警告。 所以，这就给了我们解决该问题的思路。
思路一、指定或者降低编译器的版本，支持OSX 10.14；
思路二、指定或者提升链接器的版本，支持OSX 10.15。
注意：ld（windows上是ld.exe）是链接器，全称是链接编译器（Link eDitor）。
