找不到共享库的包

Question

我正在尝试使用go-lang中的共享库，我正在关注此博文：http://blog.ralch.com/tutorial/golang-sharing-libraries/

但是当我点击构建时，我得到了一个错误：

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)

我很新，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

package libmath

func Sum(x, y int) int {
    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
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。
