找不到共享库的包

Question

我正在尝试在 go-lang 中使用共享库，我正在关注这篇博文：http : //blog.ralch.com/tutorial/golang-sharing-libraries/

但是当我点击构建时，我得到一个错误：

simo@simo:~/gopath$ go build -linkshared -o app effe/prova

src/effe/prova/prova.go:3:8: cannot find package "libmath" in any of:

/usr/local/go/src/libmath (from $GOROOT)

/home/simo/gopath/src/libmath (from $GOPATH)

我是新手，所以我也会展示我的环境......

simo@simo:~/gopath$ pwd

/home/simo/gopath

simo@simo:~/gopath$ echo $GOPATH

/home/simo/gopath

simo@simo:~/gopath$ tree

    return x + y

}

simo@simo:~/gopath$ cat src/effe/prova/prova.go 

package main

import "libmath"

import "fmt"

func main() {

    fmt.Printf("5 op 10 => %d", libmath.Sum(5, 10))

}

simo@simo:~/gopath$ go install -buildmode=shared -linkshared effe/libmath

simo@simo:~/gopath$ go build -linkshared -o app effe/prova

    /usr/local/go/src/libmath (from $GOROOT)

    /home/simo/gopath/src/libmath (from $GOPATH)

我究竟做错了什么 ？

Answer 1

“libmath”的导入路径是“effe/libmath”。在尝试更复杂的构建和执行模式之前，尝试让您的构建在标准构建模式下工作。
