LSOpenURLsWithRole() failed with error -10810

[kelvins]

Hi, I'm just trying to run the Quickstart example but I'm facing some issues.

I have installed Gallium following the step-by-step from the Installation section in the README file.

Now, I'm trying to create a new Go project following these steps:

On the Go workspace:

$ mkdir example
$ cd example
$ touch example.go
$ open example.go

I copied the following code to the example.go file:

package main

import (
  "os"
  "runtime"

  "github.com/alexflint/gallium"
)

func main() {
  runtime.LockOSThread()         // must be the first statement in main - see below
  gallium.Loop(os.Args, onReady) // must be called from main function
}

func onReady(app *gallium.App) {
  app.OpenWindow("http://example.com/", gallium.FramedWindow)
}

Then I ran the following commands:

$ go build
$ go install github.com/alexflint/gallium/cmd/gallium-bundle
$ gallium-bundle example
$ open example.app

And I got the following error message:

LSOpenURLsWithRole() failed with error -10810 for the file /Users/username/Developer/GoWorkspace/src/github.com/username/example/example.app.

Also when I try to run the go run example.go command I get it signal: killed.

I don't know if it is a Gallium issue or if I'm doing something wrong, but I couldn't figure out what is happening. If someone can help me I will appreciate.

I'm running it on MacOS Sierra Version 10.12.5 using Go version 1.8.

By the way, congratulations for the great project.

1. What happens if you just create an example.go without any references to gallium - does that build and run?

2. What happens if you log a message at the top of main() - does it get printed?

3. Did you install git lfs and can you post the output of du -hs $GOPATH/dist/Gallium.framework/Versions/A/Gallium?

1. What happens if you just create an example.go without any references to gallium - does that build and run?

Yes, it does. I have tried with the following code and it is building and running properly.

package main

import "log"

func main() {
  log.Print("Hello")
}

Output: 2017/05/31 21:03:58 Hello

2. What happens if you log a message at the top of main() - does it get printed?

I have tried the following code:

func main() {
  log.Print("Hello")
  runtime.LockOSThread()         // must be the first statement in main - see below
  gallium.Loop(os.Args, onReady) // must be called from main function
}

And it doesn't print the log, only the same message: signal: killed

3. Did you install git lfs and can you post the output of du -hs $GOPATH/dist/Gallium.framework/Versions/A/Gallium?

Yes, I did. I did run the command and got the following result:

du: /Users/username/Developer/GoWorkspace//dist/Gallium.framework/Versions/A/Gallium: No such file or directory.

I have noticed that the Gallium exec is in the following directory:

/Users/username/Developer/GoWorkspace/src/github.com/alexflint/gallium/dist/Gallium.framework/Versions/A/Gallium

So, if I run the following command:

du -hs $GOPATH/src/github.com/alexflint/gallium/dist/Gallium.framework/Versions/A/Gallium

I get the following result:

1.2M /Users/username/Developer/GoWorkspace//src/github.com/alexflint/gallium/dist/Gallium.framework/Versions/A/Gallium

My $GOPATH is /Users/username/Developer/GoWorkspace/.

Any idea?
Thanks
