Issues running on Ubuntu 12.04

[gye...@clearpathrobotics.com]

Hey, I was trying to install on precise and had some issues (worked fine in Trusty)

First, the install was a bit tricky but that's whatever

# sctp dependency

sudo aptitude install libevent-dev

cd ~/Downloads

wget http://downloads.xiph.org/releases/ogg/libogg-1.3.1.tar.gz

wget http://downloads.xiph.org/releases/opus/opus-1.0.3.tar.gz

# libogg (opus dep)

tar -zxvf libogg-1.3.1.tar.gz

cd libogg-1.3.1

./configure --prefix=/usr

make

sudo make install

cd /usr/lib

cp libogg.so.0.8.0 x86_64-linux-gnu/

sudo ldconfig

# Opus

tar -zxvf opus-1.0.3.tar.gz

cd opus-1.0.3

./configure --prefix=/usr

make

sudo make install

Alright, cool now usrsctp, libwebsock, and rabbitmq without any of them erroring. Installing janus also works as described in readme.

sudo apt-get install libmicrohttpd-dev libjansson-dev libnice-dev \

        libssl-dev libsrtp-dev libsofia-sip-ua-dev libglib2.0-dev \

        libopus-dev libogg-dev libini-config-dev libcollection-dev \

        pkg-config gengetopt doxygen graphviz

sh autogen.sh

./configure --prefix=/opt/janus # Everything checks out

sudo make && sudo make install

sudo make configs

Alright, first off when I try to run janus, I have to manually set the config path and plugin path or it will fail to load any plugins

/opt/janus/binjanus --plugins-folder=/opt/janus/lib/janus/plugins --configs-folder=/opt/janus/etc/janus --debug-level=5 

But then,

[WARN] HTTPS webserver disabled

[WARN] WebSockets support not compiled

[WARN] RabbitMQ support not compiled

[WARN] Admin/monitor HTTP webserver disabled

[WARN] Admin/monitor HTTPS webserver disabled

Damn.

If I try to stream anything through janus it will crash with a seg fault (below is trying to stream an opus file)

This is involving a negotiation (answer) as well (but we really don't care):

This is what happens if I try to start up janus without specifying the plugins folder

$ /opt/janus/bin/janus                                                                                                                             09:56

[Lorenzo Miniero]

Check if the main configuration file has some wrong setting, e.g., for the plugins folder and stuff. Apparently sometimes the configure doesn't replace the wildcards. Not sure as what's happening for the rest, since Janus is known to work on 12.04: the demos we have online for instance are deployed there.

[Lorenzo Miniero]

For some reason the configuration files are linking to a different prefix instead of /opt/janus. Fix them and it should be ok.

I still have to boot it like, but thats not so bad I suppose

/opt/janus/bin/janus --configs-folder=/opt/janus/etc/janus --debug-level=5

Still crashing after fixing paths with a seg fault. Going to retry on a fresh VM

For the segfaults you'll have to look at a backtrace with gdb. In case this appens on a fresh VM as well, please open an issue on github.

[gye...@clearpathrobotics.com]

All right, was more or less smooth on a fresh VM. Still tinkering
