Unable to compile UNIX transport

[mspanc]

I am trying to add dbus support to my phoenix app

$ mix deps.compile dbus
WARN:  Missing plugins: [rebar3_hex]
==> dbus (compile)
Compiling src/dbus_transport_unix.erl failed:
src/dbus_transport_unix.erl:15: can't find include lib "procket/include/procket.hrl"
src/dbus_transport_unix.erl:56: undefined macro 'PF_LOCAL'
src/dbus_transport_unix.erl:154: undefined macro 'UNIX_PATH_MAX'
src/dbus_transport_unix.erl:21: function init/1 undefined
ERROR: compile failed while processing /vagrant/deps/dbus: rebar_abort

I've removed src/dbus_transport_unix.erl and it compiles properly.

Do you have procket in deps?

[jeanparpaillon]

@NobbZ Maybe dependencies are not correctly declared on hex.pm ?

[mspanc]

AFAIK procket does not exist as a hex package. I am aware I can use rebar etc. but I think it's less than clear that you have to specify it separately.

[jeanparpaillon]

@mspanc I suppose you've found the answer ;) Either creates an hex package for procket either use rebar without hex.
FYI, we (especially @saa) are currently working on migrating from procket to the OTP native UNIX socket support (to be merged into OTP... soon, see #8)

[mspanc]

Cool, I think removing this dependency is the best option :) Closing then.

Hey! The OTP native UNIX socket has merged. I can take look to replace procket with native UNIX socket.

[slashmili]

Just saw that some one already is working on that #23

[jeanparpaillon]

@slashmili Hi, the guy working on that topic has disappeared :(
There were already some code working with new UNIX socket support. It only lacks updating travis CI builds for merging the code.
Do you want to give an eye on #23 ?

[slashmili]

@jeanparpaillon I did look at that and though just adding erlang 19.0 solves the problem! which it didn't https://travis-ci.org/slashmili/erlang-dbus/builds/161265849 I'll take a look to see if I can fix the broken build.

BTW I can also see that travis build for master branch is failed. So I'm not sure if after fixing the problem, I would get the same error as master branch or not

[jeanparpaillon]

erlang 19.0 is not (yet) officially available with Travis.
Before running tests, you should then install erlang 19.0 in the build env, with kerl for instance (https://github.com/kerl/kerl)

Regarding current travis failure, the situation is strange:

• build with 18.1 fails
• build with 18.2.1 passes

Plus, recently I've had issues with Travis, just relaunching a build was making the tests passing

So, upgrading to erlang 19 + relaunching a build may do the trick ;)
