importing firmata causes a signal: killed on macOS

[matipan]

Hi there, I have an issue that appeared a few days ago. The import gobot.io/x/gobot/platforms/firmata causes a signal: killed when trying to run a simple program.

This is how I verified it was that import:

package main

import (
	"log"

	_ "gobot.io/x/gobot"
	_ "gobot.io/x/gobot/drivers/gpio"
	_ "gobot.io/x/gobot/platforms/firmata"
)

func main() {
	log.Println("hello")
}

When you do a go run main.go to that file, it prints a signal: killed
Now, if we run this program:

package main

import (
	"log"

	_ "gobot.io/x/gobot"
	_ "gobot.io/x/gobot/drivers/gpio"
	// _ "gobot.io/x/gobot/platforms/firmata"
)

func main() {
	log.Println("hello")
}

It logs as I expected hello.

So there seems to be an issue with the firmata import. Any idea what it could be?

Hmm, @matipan only thing I could find on this error is https://forum.golangbridge.org/t/go-build-exits-with-signal-killed/513

OK seems like an open issue possibly golang/go#19734

Ok, thanks for pointing out that issue. It seems to be a problem with Xcode 8.3. I checked the update logs and the day this started to happen is the day Xcode got updated.

So, for anybody that reads this issue, a quick workaround is to build the program using the -ldflags and -s flags. There seems to be with an issue with how the linker in Darwin invokes dsymutil. The -s flag disables that invocation.

Another workaround is going back to Xcode 8.2

According to what is being discussed they will try to have it fix for go 1.8.1, but there are no guarantees.

As always, thanks for the quick response @deadprogram!
