我用go编译了个dll: exp.dll  exp.h C语言里: #include "exp.h" //....(直接调用dll的函数, 因为exp.h里有声明) 编译的时候 gcc test1.c exp.dll -o test1 正常,运行也正常,但是我怀疑他静态链接的时候,我把dll删了,就不能运行,又加回来,能了,说明程序是依赖这个dll的. 但是正常情况下,隐式调用都需要一个静态的导入库,一个头,一个dll吗,我这里直接把dll放进编译参数请问是什么含义?

    初学Golang，遇到一个关于调用自己编写的包里的函数的问题，请各位哥哥姐姐们帮我解答一下： P1-3是我的环境变量的配置（GOPATH,GOROOT,Path） P4是我平时听课练习写代码的文件夹（也是GOPATH的环境配置文件）P5是sdk所在的目录（GOROOT的环境配置文件）P6是自己编写的包及函数P7是引用失败的代码（utils包放在GOPATH的环境中时)P8是go run 之后的报错提示P9是引用成功的代码（utils包放在GOROOT的环境中的src中时)P10是go run 之后的运行结果。        我按照老师讲的（P6，P7的写法）但是运行失败，老师说会在GOPATH环境下的src中去找对应的包，但是它提示该目录不在GOROOT中，这是为什么，以后写程序只能吧想要引用的目录放在GOROOT环境中的src中吗？求讲讲其中的原理，有没有环境配置错的地方？求解答。
