janus編譯配置

編譯
git clone https://github.com/meetecho/janus-gateway.git
sh autogen.sh
./configure --prefix=/opt/janus --enable-websockets --enable-docs?–disable-plugin-lua

make
sudo make install
make configs//將所有的樣例配置模板安裝到/opt/janus/etc/janus文件夾下

janus.cfg? janus 的全局配置文件，但不包括其他插件的配置文件

例如 janus跟Android APP Demo通信，需要使用WeSocket插件，所以需要安裝libwebsocket插件，然后進行相關的配置

janus 默認的配置中是沒有 WebSocket 的配置的，直接啟動 Janus 會因沒有 WebSocket 配置文件而報錯。幸運的是在配置目錄中 Janus 已經給我們提供了一個 WebSocket 的示例配置文件 ： janus.transport.websockets.cfg.sample，（如果我們要通過 WebSocket 連接 Janus，則需要有個 WebSocket 的配置文件）這里我們可以直接拷貝這個示例文件：

cp janus.transport.websockets.cfg.sample janus.transport.websockets.cfg

./configure --prefix=/opt/janus --enable-websockets

If this configuration is ok for you, do a 'make' to start building Janus. A 'make install' will install Janus and its plugins to the specified prefix. Finally, a 'make configs' will install some sample configuration files too (something you'll only want to do the first time, though).

注意--enable-docs加載不成功，因此去掉該配置項

checking for doxygen... doxygen
checking for dot... no
configure: error: doxygen or dot not found. See README.md for installation instructions or remove --enable-docs
