JSDP : Simple library implementation of Session Description Protocol (SDP)

Simple library implementation of Session Description Protocol RFC 4566 # SDP: Session Description Protocol. This library provides parsing and generating of SDP that can be used with other session protocols such as SIP.

Supported Operated Systems

jSdp currently support building on Linux and MacOs.

Dependencies for Running Locally

• cmake >= 3.7
  • All OSes: click here for installation instructions
• make >= 4.1 (Linux, Mac)
  • Linux: make is installed by default on most Linux distros
  • Mac: install Xcode command line tools to get makepackages/make.htm)
• gcc/g++ >= 9.3
• Linux: gcc / g++ is installed by default on most Linux distros
• Mac: same deal as make - install Xcode command line tools
• clang >= 9.3

Basic Build Instructions

1. Clone this repo.
2. Make a build directory in the top level directory: mkdir build && cd build
3. Compile: export CXX=<path_to_g++9> && export CC=<path_to_gcc9> && cmake .. && make
4. Link generated library to you project
