问题
I am trying to use janus. First step, installation. I followed the instructions here. All is well. However, when I run
configure prefix=/opt/janus
Relevant portions of the output are:
...
checking for TRANSPORTS... yes
checking for MHD... yes
checking for lws_create_vhost in -lwebsockets... no
checking for amqp_error_string2 in -lrabbitmq... no
checking for MQTTAsync_create in -lpaho-mqtt3a... no
checking for PLUGINS... yes
checking for SOFIA... yes
checking for OPUS... yes
checking for OGG... yes
checking for EVENTS... yes
checking that generated files are newer than configure... done

MY PROBLEM IS WITH THE ENTRY WebSockets: no.
I checked in /usr/lib and here are the relevant files there:
/usr/lib/libwebsockets.a /usr/lib/libwebsockets.so
/usr/lib/libwebsockets.so.11 /usr/lib/libwebsockets.so.5
And in /usr/include
/usr/include/libwebsockets.h
So, I think that libwebsockets is installed properly. What needs to be done to get the webSockets transport enabled?
I did look at this too.

Since https://github.com/meetecho/janus-gateway/pull/996
You need libwebsockets >= 2.0.0. Trusty has an old version.
You have to compile it. See the description of janus how to do that.
