How to start Janus WebRTC gateway?

Question

I installed successful Janus on /usr/local/lib and I re-configure to start Janus. But when I do sudo janus, I get this error:

*/ libjanus_http.so and libmicrohttpd.so.12 are exist on usr/local/lib/janus/transport and /usr/local/lib

What does the error mean?

I guess you missed a step or two, maybe it will fix your issue it did for me :

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 libwebsockets-dev pkg-config gengetopt automake libtool doxygen graphviz git cmake

sudo apt-get install libavformat-dev

mkdir -p ~/build

cd ~/build

git clone git://github.com/meetecho/janus-gateway.git


cd janus-gateway

sh autogen.sh

./configure --disable-data-channels --disable-websockets --disable-rabbitmq --disable-docs --prefix=/opt/janus LDFLAGS="-L/usr/local/lib -Wl,-rpath=/usr/local/lib" CFLAGS="-I/usr/local/include"

make && sudo make install
sudo make configs

Then :

cd /opt/janus/bin/ 

./janus -F /opt/janus/etc/janus/
