Hi, I am trying to use Meson, and I did the followings to get dub 
packages:

    dub fetch hunt-net
    dub fetch hunt-proton
    dub build hunt-net
    dub build hunt-proton

when I have this line in my meson.build file:

    dependency('hunt-net', method: 'dub')

It works fine:

    Run-time dependency hunt-net found: YES 0.4.6

But when I change it to

    dependency('hunt-proton', method: 'dub')

It simply says:

    Run-time dependency hunt-proton found: NO
    ... ERROR: Dependency "hunt-proton" not found

And when I looked at meson-log.txt, I couldn't find any clue on 
why that happens:

     Determining dependency 'hunt-proton' with DUB executable 
'.../dlang/dmd-2.091.0/linux/bin64/dub'
     Run-time dependency hunt-proton found: NO

So I completely cannot figure out why hunt-net is resolvable but 
hunt-proton is not. Can anyone help me understand how meson 
resolves these dependencies? Thanks!

I have a feeling that it might be because of the fact that 
hunt-proton has a "beta" in its version:

   hunt-net 0.4.6: /home/.../.dub/packages/hunt-net-0.4.6/hunt-net/
   hunt-proton 1.0.0-beta.3: 
/home/.../.dub/packages/hunt-proton-1.0.0-beta.3/hunt-proton/

However, this does not help me solve the problem. Even if I add a 
"version" parameter to the dependency() function, it still does 
not resolve hunt-proton.

Any help will be greatly appreciated, thanks.

So I found that the issue is that dub.json file in hunt-proton 
has an entry referring to the parent package with a relative file 
path in it. When that relative file path is removed, Meson can 
find hunt-proton.

However, even after Meson found it, there are two bad behaviors:

(1) Meson refused to automatically add the dependencies of 
hunt-proton, and I had to manually add them to meson.build.
(2) Meson did not automatically add the appropriate 
d_module_versions setting that is required by hunt (the 
HAVE_EPOLL/HAVE_IOCP/... setting), and I had to manually add that 
too.

Anyway, after manually tweaking the meson.build file like above, 
I got it to work (except that compiling/linking seems quite slow).

Sorry for the inconveniences. We are still testing Hunt-AMQP. The 
problems about dub.json will be fixed soon.

Thanks for the reply! BTW is hunt-amqp for AMQP 1.0 only? Because 
when I try it on an AMQP 0.9 server, it does not seem to connect. 
Thanks again!

We are using RabbitMQ v3.8.2 for test. The hunt-amqp is based on 
AMQP 1.0, and is not tested with AMQP 0.9.

So, wo suggest you to upgrade the MQ server.
