Mosquitto 1.4.2 Websocket support

0 votes

I'm trying to utilize Mosquittos recent update to support websockets in the broker. I'm running Mosquitto v1.4.2 and I've added the following lines to the mosquitto configuration file (mosquitto.conf): (OS is CentOS)

listener 10001 127.0.0.1
protocol websockets

listener 1883
protocol mqtt

When I try and start the broker with the new configuration I get the following :

$ mosquitto -c /etc/mosquitto/mosquitto.conf
Error: Websockets support not available.
Error found at /etc/mosquitto/mosquitto.conf:16.
Error: Unable to open configuration file.

I was under the assumption that version 1.4 and above of Mosquitto has websocket support now (don't have to build from source to enable websocket support like you had to before v1.4) so I'm wondering what I'm missing. Any help on what direction to look to troubleshoot the problem is appreciated.

In the dir mosquitto-1.4.X edit the file config.mk:

# Build with websockets support on the broker.
WITH_WEBSOCKETS:=yes

Then run in the dir mosquitto-1.4.X

make
sudo make install

Edit the configurations /etc/mosquitto/mosquitto.conf

listener 10001 127.0.0.1
protcol websockets

And restart

mosquitto -c /etc/mosquitto/mosquitto.conf
