Erlang OTP: 19.3

getting this error when running "make":

I am building release v2.0.7 using docker,

The emq-relx Make recipe has started to fail, with the error:
Dependency emq_mod_retainer is specified as a dependency but is not reachable by the system.

I see a in a recent commit emqx/emqx-retainer@1e3063a that emq_mod_retainer project has been renamed to emq_retainer

Would this be causing the build to fail, is there any way to work around this? (without waiting on a release)

Which causes most of the functions to not work.

What have I done wrong, or it's a problem with relx 2.3.10?

Does have any scheme to support dynamic blacklists based on IP or MQTT client IDs?

I keep getting this message when building emq-relx on Ubuntu 16.04 LTS with Erlang OTP 19.

Anything I'm missing?

when i update emqttd to emq2.0, I did not change the configurations, but when i use lager:error, it prints nothing. (tested in ubuntu14.04)
Then I change the level to info:
{lager, [ {colored, true}, {async_threshold, 5000}, {error_logger_redirect, false}, {crash_log, "log/emqttd_crash.log"}, {handlers, [ {lager_console_backend, info}, %%NOTICE: Level >= error %%{lager_emqtt_backend, error}, {lager_file_backend, [ {formatter_config, [time, " ", pid, " [",severity,"] ", message, "\n"]}, {file, "log/emqttd_error.log"}, {level, info}, {size, 104857600}, {date, "$D0"}, {count, 30} ]} ]} ]},

it also prints nothing.

emqttd-relx is being used to make a build of the broker. It seems there is no instruction how to add new plugin to emqttd-relx and build it. Can someone help?

I need to understand how the persistent conf works as defined in the emq.conf.

When my subscriber client is disconnected from the n/w (due to any failure), the msgs from the publisher are reported dropped by the EMQ broker. I require these msgs to be delivered to the subscriber once it comes back. Is there any other configuration which is needed to be taken care in conjunction.

For the error I understand that some modules are built to be compiled with Erlang OTP 22. I also tryed installing OTP 22 but the Makefile checks that the version should be 21 and stops the compilation too.

The output of erl is:

Any help will be appreciated.

For instance I could not find where asn1 is used. Trimming down the list will result in a smaller release size.

Description

I am trying to upgrade from v2.1.2 to v2.2.0

Note I cannot go to v2.3.x as I need to use the stable version of emq.

I am building within docker,
I have a custom build which clones emq-relx at the release tag then runs Make to build the release..

I seem to be experiencing the bug referenced in emqx/emqx#1389

Would that be possible?

i.e. I am getting

 terminated with reason: no try clause matching ok in emqttd_client:'-send_fun/2-fun-2-'/4 line 142

I see the fix was to pin esockd to v5.1

dep_esockd = git https://github.com/emqtt/esockd v5.1

Maybe this wasn't done on the v2.2.x release perhaps?

Every time trying connect via an MQTT client, Server responds with error, disconnecting the client.

Running on:
Version 2.3.1 - Mac OSX sierra 10.12.6 (Erlang/OTP 19 [erts-8.3])

Error:
`
gen_server <0.1453.0> terminated with reason: no try clause matching ok in emqttd_client:'-send_fun/2-fun-2-'/4 line 142

I have an elixir plugin containing hooks, acl, auth modules to run with emqttd v 2.0 broker. I referred http://elixir-lang.org/crash-course.html#adding-elixir-to-existing-erlang-programs to make it work with the emqttd. The issues I am facing is:

1. Compile my elixir files using erlang.mk
2. If anything else is needed other than setting ERL_LIBS to /lib/elixir/lib.

Hello,
we need to export the ssl port (8883) to devices, so necessary to set a bigger backlog for this port,
but I tried to set following configurations:
mqtt.listener.ssl.backlog = 8192
or
mqtt.listener.ssl.tcp.backlog = 8192

it didn't work, the mqttd failed to start, how to set the backlog for SSL listener?

How to resolve it? Thank you!

If we start the broker with bin\emqttd start command, the broker will consume more and more cpu/memory and then crash.

I successfully built Emqtt on raspberry pi 3 model b using these series of commands

sudo apt-get update

sudo apt-get install erlang-dev erlang-edoc erlang-eunit erlang-reltool erlang-crypto erlang-eldap erlang-public-key erlang-runtime-tools erlang-ssl
sudo apt-get install wget libssl-dev ncurses-dev
wget http://www.erlang.org/download/otp_src_18.3.tar.gz
tar -xzvf otp_src_19.3.tar.gz
cd otp_src_18.3/
./configure
make
sudo make install

git clone https://github.com/emqtt/emq-relx.git
cd emq-relx && make
cd _rel/emqttd && ./bin/emqttd console

and the emqtt works as expected with console and start.

But I couldn't make it start at boot. I tried this script https://github.com/emqtt/emq-package/blob/master/deb/debian/init.script
with these changes :

NAME=emqttd
DAEMON=/opt/emqttd/bin/$NAME
SCRIPTNAME=/etc/init.d/$NAME

but it doesn't work

Errors:
In the first place it said that the emqtt user not found then I added that user and set it as owner of the opt/emqttd folder.
now the status is :

emqttd.service - LSB: Erlang MQTT Broker

Is there something I'am missing ?

I am building release v2.0.7 using docker,

I am getting a runtime error,

[error] Lager failed to install handler {lager_syslog_backend,{"emq",local0}} into lager_event, retrying later : {error, {"no such file or directory", "syslog.app"}}

Looking at the Makefile for tag v2.0.7 lager is a dependency,
Comparing to 2.1, it appears that lager_syslog has been added as a dependency for 2.1

How could a dependency that wasn't in 2.0.7 be working it's way into my build?

Environment

• OS: unbuntu 16.04
• Erlang/OTP: 21
• EMQ: 2.3.11

It would not work if I ran './bin/emqttd_ctl clients list':
Node '[email protected]' not responding to pings.

https://github.com/emqtt/emq-relx/blob/8b6b49ad94b2f4dee7478e9a10d064a2c5f468ce/bin/emqttd_ctl#L71

Should we change the command 'cut -d = -f 2' to 'cut -d = -f 2-' ?
Like follows:
COOKIE=egrep '^[ \t]*node.cookie[ \t]*=[ \t]*' $RUNNER_ETC_DIR/emq.conf 2> /dev/null | tail -1 | cut -d = -f 2-

use elang 19.1
git clone https://github.com/emqtt/emq-relx.git
cd emq-relx && make

make got the error:
src/esockd_cidr.erl:59: syntax error before: ?

I downloaded the source code package, compiled directly on the centos7 server exploded compilation error, as follows:

in goldrush error info: rebar command not found
copy rebar to goldrush folder,modify makefile @ReaBar to ./rebar
the question is ok

I am building on Mac OS v10.12.3 with Erlang v19. I had a few issues while building initially since the rel/ folder was not present. I fixed that by using the configuration from the downloadable mac os version and after that all the build issues disappeared.

After building, when I try to run the binary, this is what I get:

I cannot understand why I had this error, but my real problem now is that I cannot load any plugin.
When I tried to load such a plugin I got this error as follows:
