Thanks for looking into this.
I found a problem with the code:-
{{make}} failed, complaining about a lack of type on
{{PN_TRANSPORT_READ_CLOSED}} in _event.h_.
I changed line 363 to read:-
{{static const pn_event_type_t PN_TRANSPORT_READ_CLOSED =
PN_TRANSPORT_TAIL_CLOSED;}}
The project then built successfully (pull request =
https://github.com/alanconway/qpid-proton/pull/1).
I'm now testing my client app, and will provide an update shortly.

Thanks for looking into this.
I found two problems:-
h2. 1. make failed
It complained about a lack of type on {{PN_TRANSPORT_READ_CLOSED}} in _event.h_.
I changed line 363 to read:-
{{static const pn_event_type_t PN_TRANSPORT_READ_CLOSED =
PN_TRANSPORT_TAIL_CLOSED;}}
The project then built successfully (pull request =
https://github.com/alanconway/qpid-proton/pull/1).
h2. 2. negative WaitGroup counter
Then, when I ran my _receive.go_ client, it failed with the following error:-
{code}

I haven't yet managed to solve this second one. Sample code is in my repo -

> go binding does not create durable subscriber

> Key: PROTON-1415
> URL: https://issues.apache.org/jira/browse/PROTON-1415
> Project: Qpid Proton
> Issue Type: Bug
> Components: go-binding
> Affects Versions: 0.17.0
> Environment: Docker for Windows 1.13.1
> Docker golang:1.7
> ActiveMQ 5.14.3 (Java 1.8.0_111)
> Reporter: Jeremy Gooch
> Assignee: Alan Conway
>
> When creating a subscription from Qpid Electron, the subscription name is not
> set, meaning that durable subscriptions cannot be created.
> Example code ->
> https://github.com/goochjs/amqp-activemq-python-go/blob/master/go-electron/receive.go
> Go example snippet (setting container ID):-
> container = electron.NewContainer(fmt.Sprintf("receive-client[%v]",
> os.Getpid()))
> Go example snippet (failing to set subscription name):-
> if r, err := c.Receiver(electron.LinkName(SubscriptionName),
> electron.Source("topic://"+AmqpResourceName)); err == nil {
> For comparison, I have a working Qpid Proton Python client, which sets both
> connection ID and subscription name ->
> https://github.com/goochjs/amqp-activemq-python-go/blob/master/python-proton/message_receiver.py
> Python example snippet (setting container ID):-
> # Name the subscription after the script file name
> event.container.container_id = __file__
> Python example snippet (setting subscription name):-
> messaging_connection = event.container.connect(self.url)
> event.container.create_receiver(
> messaging_connection,
> self.resource,
> name=self.subscription_name,
> options=durable
> )
