As you can see REST is disabled by default when i run
./configure --prefix=/opt/janus
I want REST to be enable how to enable it?
./configure --help | grep -i rest
libmicrohttpd was not installed.(Because its outdated. janus-gateway needs libmicrohttpd not libmicrohttpd-dev. most of the installation guides recommends to install libmicrohttpd-dev.)
So i had to install the below libmicrohttpd from gnu and now its working perfectly
wget http://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-0.9.59.tar.gz
tar xvf libmicrohttpd-0.9.59.tar.gz
cd libmicrohttpd-0.9.59
./configure
make
sudo make install
sudo ldconfig
