go returned unspecified error

[ghost]

Hello! I'm having trouble when running goxc -bc="windows,386" -d=dist -q with Go 1.4 in my project's folder (/home/nick/apps/project). Thank you in advance for looking at this!

Note: though it advices me to run goxc -t, I've already done that.

It returns the following (sorry for so long output):

nick@ubuntu:~/apps/project$ goxc -d=dist -bc="windows,386" -q

Hi there, thanks for the details.

I've been trying Go1.4 and it seems to work fine for me so far.

• Are you using the Mercurial repo from code.google.com? This is still the recommended repo for installing-from-source. I have tried the github repo, it didn't build for me.
  • Can you try again without the -q option? It might help give more clues. If not, the -v option could also help.

So, if not, then the next step is to check that you can cross-compile the toolchain manually (without goxc):

export GOOS=windows
export GOARCH=386
cd "$GOROOT/src" # or just cd into /home/nick/go/src
./all.bash

I find it a bit weird that your GOPATH is inside your GOROOT, but each to their own, as long as it's not a mistake.

Let me know what you find. Ta

Hmm. I moved GOPATH to /home/nick/gopath. Hello World builds well, but my application doesn't. It uses go-gtk library. Here's the code:

package main

import (
    "github.com/mattn/go-gtk/gtk"
    "os"
)

func main() {
    gtk.Init(&os.Args)
    window := gtk.NewWindow(gtk.WINDOW_TOPLEVEL)
    window.SetTitle("Hello World")
    window.Connect("destroy", gtk.MainQuit)

    gtk.Main()
}

And the error I get:
http://paste.debian.net/hidden/fc0d6afb/

It seems like the problem is here. But this is a simple import and library code is already built with go get command. go build command shouldn't be called in this folder at all, or I'm mistaking?

main.go:4:2: no buildable Go source files in /home/nick/gopath/src/github.com/mattn/go-gtk/gtk

UPD: Oh, I've forgotten to tell you that I can build toolkit with all.bash successfully. However, I reinstalled go then and tried to run goxc on Hello World using clean go installation, and that worked.
UPD: Running GOOS=windows GOARCH=386 CGO_ENABLED=0 go build -o appname.windows main.go in the project's folder gave me that error. Going deeper.
UPD: Running with CGO_ENABLED=1 returns the following:

nick@ubuntu:~/apps/test$ GOOS=windows GOARCH=386 CGO_ENABLED=1 go build -o appname.windows main.go
# runtime/cgo
gcc: error: unrecognized command line option ‘-mthreads’

So, can I compile packages which import C library for another platform at all?

[ghost]

Closing as not goxc related. However, it would be great to see your piece of advice.

[laher]

Hey there, yes, unfortuntately goxc isn't much use for cross-compiling C/C++ dependencies. There's some other projects you might want to look at to help with that, but you'd need to cross-compile the GCC toolchain, which is a lot more work. You might want to look at a project called xgo, which is moving towards a better solution: https://github.com/karalabe/xgo

Oh and I think you're much better off keeping your GOPATH outside of GOROOT. There's no real benefit to mixing them up.

Cheers
