Could you please try: `CC=gcc go get github.com/mattn/go-gtk` ? Probably your go is using clang?

I'll look into it in later

Hmm, I don't reproduce this as your said. I need to make development-environment for gtk.

I tried your [code](https://github.com/mattn/go-gtk/issues/289#issuecomment-262029177) on Ubuntu 16.04 (clean installed) and go1.7.3. But can't reproduce.

Currently, not have helper.

Since your gtk libraries are not compiled as static library.
