Use gocode word complete, example input fmt.

GitHub: https://github.com/nsf/gocode
Install gocode

$ export GOROOT=$HOME/go
$ export PATH=$HOME/go/bin:$PATH
$ go get -u github.com/nsf/gocode

when running the above commands the following happens (see below) and code completion still does not work.
(also the binary download of liteide already contains an executable "gocode" and it is started and running while the IDE is running, is this the same gocode as mentioned above (so i don't need to install it anymore) or os this some additional tool?)
