Compatibility for libzmq3 / older Debians?

[dginev]

Mostly an FYI issue, feel free to close right away.

I have had a crate depending on rust-zmq that has been running nicely on Debian jessie and wheezy for over a year now, and has built nicely with Travis with only adding:

addons:
  apt:
    packages:
      - libzmq3-dev

I decided to update to the latest master today, since I have been tracking the github repo, and sadly the comfy travis config is no longer supported, and neither are my old-fashioned Debian servers. Clearly updating to a 4.* libzmq from source would be one way out, but that's something I'd like to postpone as much as possible, extra complexity in setup and all.

Long story short, I wanted to share my updated Cargo.toml dependency which still works on legacy systems, I simply copied the last revision sha that was operational on Travis for me:

[dependencies.zmq]
git = "https://github.com/erickt/rust-zmq.git"
rev = "87a6bd2a7ce09200b6f0a5bdc08ef684c4951f21"

Since the crate is updated on crates.io somewhat rarely, I'll freeze the revision until an upgrade happens somewhere: OS upgrade on the servers, or added backwards compatibility to rust-zmq. Just a tip that may keep other rust-zmq users happy until the world moves forward.

I have an update in #115 that will restore compatibility with 4.0.x and even 3.2.x.

Once this is merged, it would be great if you could verify that it still works with your crate.

@dginev Now that #115 has been merged, could you verify that your builds using older libzmq started working again, and close this issue if so?

... waiting for the nightly fix for broken crate updates to land and I'll give it a spin, thanks!

@dginev Any news on this issue?

[dginev]

Well, i was still waiting on the cargo fix to land, but there seems to be a viable workaround that I managed to get to work for now.

I have tried the latest rust-zmq HEAD (commit be88b5f ) and can confirm this issue is resolved - both on travis and my Debian servers.

Thanks!!
