error: pebbe/zmq4/reactor.go:10:4: undefined: State

[Zireael]

Getting error from pebbe as dependency of gophernotes.
I've raised an issue with gophernotes, but it might be it's more something to do with pebbe:
gopherdata/gophernotes#188
Installation under alpine linux worked for me - not sure what I'm missing for Debian/Ubuntu

During gophernotes install via Debian/Ubuntu dockerfile I get error:

Dockerfile (based on Ubuntu/jupyterlab) with failing example
Trying to go install pebbe or go install gophernotes fails:

libzmq3-dev is required for zmq4. You made it a comment, so it's not installed.

[Zireael]

Hi, libzmq3-dev is installed earlier in my base image. I commented it out in my dockerfile just before gophernotes because I was specifically checking to install it, but got installer message that libzmq3-dev is already in the system.
I updated the minimum failing example with specifically installing libzmq3-dev and then listing all the packages installed.

Fail message still remains (excuse crossed out lines - that's markdown syntax getting in the way):

RUN go get -u github.com/gopherdata/gophernotes
github.com/gopherdata/gophernotes/vendor/github.com/pebbe/zmq4
/go/src/github.com/gopherdata/gophernotes/vendor/github.com/pebbe/zmq4/reactor.go:10:4: undefined: State
/go/src/github.com/gopherdata/gophernotes/vendor/github.com/pebbe/zmq4/reactor.go:11:9: undefined: State
The command '/bin/sh -c go get -u github.com/gopherdata/gophernotes' returned a non-zero code: 2

I believe you need CGO_ENABLED to work. If CGO_ENABLED=0, then you will run into this problem.
