"signal: killed" or "Killed: 9" running on OSX Sierra

[theothertomelliott]

I started seeing the message "Killed: 9" in a program using gopsutil when building today. This appears to be related to an update to version 8.3 of Xcode's Command Line tools. My program is using the net and process packages.

I can reproduce this (albeit with a different message), with the example from the README:

package main

import (
"fmt"

"github.com/shirou/gopsutil/mem"

)

func main() {
v, _ := mem.VirtualMemory()

// almost every return value is a struct
fmt.Printf("Total: %v, Free:%v, UsedPercent:%f%%\n", v.Total, v.Free, v.UsedPercent)

// convert to JSON. String() is also implemented
fmt.Println(v)

}

Which outputs "signal: killed".

May be because of today's update of Sierra 10.12.4?

@qiukeren In my case it was the XCode update. I managed to work around it by uninstalling XCode and installing the 8.2 version of the command line tools from https://developer.apple.com/download/more/. I've not re-installed XCode yet, but will be using 8.2 when I do.

Should hopefully get you up and running until the problem can be root-caused.

@theothertomelliott truely, today's update contains sierra update and command line tools update.

I found some similiar issues on killed 9 ,
which is caused by cgo.

this is a TEMP fix:

replace go build with go build -ldflags=-s

Thanks for the information.

I think this is a macOS bug, so I labeled this issue wontfix.

golang/go#19734

@qiukeren thanks go build -ldflags=-s systools.go ok

[shirou]

Go 1.8.1 fixes this problem. or , -ldflags=-s can fix also.
