4025: cannot use value (type unsafe.Pointer) as type C.gpointer

[Petricevic]

Debian 64 with Mate gtk installed I this message and I can not go on: go/src/github.com/mattn/go-gtk/gtk/gtk.go:4025: cannot use value (type unsafe.Pointer) as type C.gpointer in argument to _Cfunc_to_GTreePath thank you

what version of go do you use? gccgo?

[Petricevic]

paolo@paolo:~$ go version go version go1.3.3 linux/amd64

paolo@paolo:~$ gccgo version bash: gccgo: command not found

bits older. But if this fixes your problem, I'll merge this.

Could you please send me pull-request?

[Petricevic]

I tried to compile the example: go-gtk/example/action/

[mattn]

go 1.3 is too old.

[Petricevic]

as an example I can try?

[mattn]

Sorry, I don't use go1.3, so I don't know which you can try.
