[mosquitto-dev] Building mosquitto auth-plugin.

[Leandro Roggerone <ingrogger@xxxxxxxxx>]

Hi guys ... I can not build mosquitto auth plugin on my centos 7 server.

This is what im doing:

cd /usr/src/
git clone https://github.com/eclipse/mosquitto.git
git clone https://github.com/jpmens/mosquitto-auth-plug.git
cd  mosquitto-auth-plug/
cp config.mk.in config.mk
vim config.mk
:
###############
BACKEND_MYSQL ?= yes
.
# Specify the path to the Mosquitto sources here
# MOSQUITTO_SRC = /usr/local/Cellar/mosquitto/1.4.12
MOSQUITTO_SRC = /usr/src/mosquitto

# Specify the path the OpenSSL here
OPENSSLDIR = /usr/bin
###############

then :
make , yelds:

Selected backends:          MySQL
Using mosquitto source dir: /usr/src/mosquitto
OpenSSL install dir:        /usr/bin

If you changed the backend selection, you might need to 'make clean' first

Question:
Do I need to build mosquitto also ? (It works out of the box using yum install mosquitto).

Is it easier to install in other distro ? debian perhaps ?.

Any help would be great!!!
Thanks.
