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、Source the bbndk environment file

Command: source $BBNDK_DIR/bbndk-env.sh

($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.
