Getting Started
******************************

Building PJSUA2
======================
The PJSUA2 C++ library will be built by default by PJSIP build system.

Building Python and Java SWIG Modules
======================================
The SWIG modules for Python and Java are built by invoking ``make`` and ``make install`` manually from ``pjsip-apps/src/swig`` directory. The ``make install`` will install the Python SWIG module to user's ``site-packages`` directory.

Requirements
------------

#. ``JDK``.
#. ``Python``, version 2.7 or above is required.
   For **Linux/UNIX**, you will also need ``Python developent package`` (called ``python-devel`` (e.g. on Fedora) or ``python2.7-dev`` (e.g. on Ubuntu)). For **Windows**, you will need MinGW and ``Python SDK`` such as `ActivePython-2.7.5`_ from `ActiveState`_.

.. _`ActivePython-2.7.5`: http://www.activestate.com/activepython/downloads
.. _`ActiveState`: http://www.activestate.com

Testing The Installation
------------------------
To test the installation, simply run python and import ``pjsua2`` module::

  $ python
  > import pjsua2
  > ^Z


Using in C++ Application
========================
As mentioned in previous chapter, a C++ application can use *pjsua2* natively, while at the same time still has access to the lower level objects and the ability to extend the libraries if it needs to. Using the API will be exactly the same as the API reference that is written in this book.

Here is a sample complete C++ application to give you some idea about the API. The snippet below initializes the library and creates an account that registers to our pjsip.org SIP server.

.. code-block:: c++
    
  #include <pjsua2.hpp>
  #include <iostream>
  
  using namespace pj;
  
  // Subclass to extend the Account and get notifications etc.
  class MyAccount : public Account {
  public:
      virtual void onRegState(OnRegStateParam &prm) {
          AccountInfo ai = getInfo();
          std::cout << (ai.regIsActive? "*** Register:" : "*** Unregister:")
                    << " code=" << prm.code << std::endl;
      }
  };

  int main()
  {
      Endpoint ep;
      
      ep.libCreate();
      
      // Initialize endpoint
      EpConfig ep_cfg;
      ep.libInit( ep_cfg );
      
      // Create SIP transport. Error handling sample is shown
      TransportConfig tcfg;
      tcfg.port = 5060;
      try {
          ep.transportCreate(PJSIP_TRANSPORT_UDP, tcfg);
      } catch (Error &err) {
          std::cout << err.info() << std::endl;
          return 1;
      }
      
      // Start the library (worker threads etc)
      ep.libStart();
      std::cout << "*** PJSUA2 STARTED ***" << std::endl;
      
      // Configure an AccountConfig
      AccountConfig acfg;
      acfg.idUri = "sip:test@pjsip.org";
      acfg.regConfig.registrarUri = "sip:pjsip.org";
      AuthCredInfo cred("digest", "*", "test", 0, "secret");
      acfg.sipConfig.authCreds.push_back( cred );
      
      // Create the account
      MyAccount *acc = new MyAccount;
      acc->create(acfg);
      
      // Here we don't have anything else to do..
      pj_thread_sleep(10000);
      
      // Delete the account. This will unregister from server
      delete acc;
      
      // This will implicitly shutdown the library
      return 0;
  }
