Adding gokogiri dependency causes `Killed: 9` exit

Question

The environment I am using is go1.8 on MacOS Sierra.

The code:

package main

import (
    "fmt"
    "io/ioutil"

    "github.com/moovweb/gokogiri"
    "github.com/moovweb/gokogiri/xpath"
)

func main() {
    fmt.Println("hello world")
    b, _ := ioutil.ReadFile("x.xml")
    fmt.Println(string(b))
    doc, _ := gokogiri.ParseXml(b)
    compiled := xpath.Compile("/path/to/node")
    ss, _ := doc.Root().Search(compiled)
    for _, s := range ss {
        fmt.Println(s.Content())
    }
}

After I build and run:

$ ./hello-world
Killed: 9

Even the hello world message is not printed. Later on, on investigating the gokogiri README, I saw instructions on installing libxml2. So I did brew install libxml2 and tried, and that also did not fix the issue.

Answer 1

According to similar issue, and also in Golang issue #19734, cgo command broken on darwin after performing c tool-chain (Xcode 8.3) update from Apple.

The solution: upgrade to go1.8.1 or above or add -ldflags=-s to build or test command, e.g. go build -ldflags=-s.
