About how to build PJSIP under linux environment

       PJSIP is a free and open source multimedia communication library written in C language  implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. It combines signaling protocol (SIP) with rich multimedia framework and NAT traversal functionality into high level API that is portable and suitable for almost any type of systems ranging from desktops, embedded systems, to mobile handsets.For example,PJSIP can be used as BlackBerry 10 platform's third-party components for VOIP protocol communication.

 

First, you must to install linux system on your PC,such as Ubuntu.

1、Run below command to install required tools if you don't have. (E.g. svn 、git、jdk、gcc)

        Command: sudo apt-get install git

                           sudo apt-get install subversion
  
                           sudo apt-get install g++

                           sudo apt-get  install  build-essential  

                           sudo apt-get build-dep fcitx

                           sudo apt-get install yum

2、Use Browser to download BlackBerry IDE and SDK and install.

 

        Blackberry SDK version : 10.1.0.4828

      （Note:Currently using this, if you use Blackberry SDK version 10.2 to build the PJSIP,the resource import

        will be error with missing  some package）

        Download URL : http://developer.blackberry.com/native/downloads/

 

3、Checkout PJSIP BB10 demo from below url

       Command：git clonehttps://github.com/bobcripps/bb10-pjsipdemo.git  
 

4、 Get the PJSIP source

         Enter the path :  cdbb10-pjsipdemo\pjbuildscripts\ (Checkout after step 3)
 
         Command: ./getpjsource   （spend some time）
 

5、Change the file below

        Enter the path : cd pjsip-checkout/trunk/pjsip/include/pjsua-lib/
        File to change: vi  pjsua.h

        Enter :  Esc ,change to Command Model

        Input  :  /PJSUA_SDP_SESS_HAS_CONN

        Enter :  Enter, to searchPJSUA_SDP_SESS_HAS_CONN value

        Enter :  i , change to Insert Model, set the value of PJSUA_SDP_SESS_HAS_CONN to 1
        Enter :  Esc ,change to Command Model
        Input  : :wq , save and quite 

6 And , Source, and the environment is file bbndk
 
       Command that: source $ BBNDKDIR / bbndkenvsh     

       ($BBNDK_DIR means the SDK installation directory path,and you'd better run this in your BB10 NDK directory)
 
7、Compile and build the sdkfiles
 
       Enter the path : cd bb10-pjsipdemo\pjbuildscripts
 
       Command: ./buildpjsip

8、 Put the upzip of sdkfiles zip file
 
      Enter the path : cd \bb10-pjsipdemo\pjbuildscripts

      Command: ./createsdkoverlay
 
9、the sdkfile.zip will be created in the bb10-pjsipdemo\pjbuildscripts when step 8 finished.
