Getting Started: Building and Using PJSIP and PJMEDIA [Last Update: $Date: 2007-02-02 20:42:44 +0000 (Fri, 02 Feb 2007) $] Print Friendly Page _________________________________________________________________ This article describes how to download, customize, build, and use the open source PJSIP and PJMEDIA SIP and media stack. The online (and HTML) version of this file can be downloaded from http://www.pjsip.org/using.htm Quick Info _________________________________________________________________ Building with GNU tools (Linux, *BSD, MacOS X, mingw, etc.) Generally these should be all that are needed to build the libraries, applications, and samples: $ ./configure $ make dep && make clean && make Building Win32 Target with Microsoft Visual Studio Generally we can just do these steps: 1. Visual Studio 6: open pjproject.dsw workspace, 2. Visual Studio 2005: open pjproject-vs8.sln solution, 3. Create an empty pjlib/include/pj/config_site.h, and 4. build the pjsua application. Building for Windows Mobile Generally these are all that are needed: 1. Open pjsip-apps/build/wince-evc4/wince_demos.vcw EVC4 workspace, 2. Create an empty pjlib/include/pj/config_site.h, and 3. build the pjsua_wince application. Invoking Older Build System (e.g. for RTEMS) Generally these should be all that are needed to build the libraries, applications, and samples: $ ./configure-legacy $ make dep && make clean && make Locating Output Binaries/Libraries Libraries will be put in lib directory, and binaries will be put in bin directory, under each projects. Running the Applications After successful build, you can try running pjsua application on pjsip-apps/bin directory. PJSUA manual can be found in http://www.pjsip.org/pjsua.htm page.

Getting the Source Code Distribution _________________________________________________________________ All libraries (PJLIB, PJLIB-UTIL, PJSIP, PJMEDIA, and PJMEDIA-CODEC) are currently distributed under a single source tree, collectively named as PJPROJECT or just PJ libraries. These libraries can be obtained by either downloading the release tarball or getting them from the Subversion trunk. 1.1 Getting the Release tarball _________________________________________________________________ Getting the released tarball is a convenient way to obtain stable version of PJPROJECT. The tarball may not contain the latest features or bug-fixes, but normally it is considered more stable as each will be tested more rigorously before released. The latest released tarball can be downloaded from the http://www.pjsip.org/download.htm. 1.2 Getting from Subversion trunk _________________________________________________________________ PJPROJECT Subversion repository will always contain the latest/most up-to-date version of the sources. Normally the Subversion repository is always kept in a "good" state. However, there's always a chance that things break and the tree doesn't build correctly (particularly for the "not-so-popular" targets), so please consult the mailing list should there be any problems. Using Subversion also has benefits of keeping the local copy of the source up to date with the main PJ source tree and to easily track the changes made to the local copy, if any. What is Subversion Subversion (SVN) is Open Source version control system similar to CVS. Subversion homepage is in http://subversion.tigris.org/ Getting Subversion Client A Subversion (SVN) client is needed to download the PJ source files from pjsip.org SVN tree. SVN client binaries can be downloaded from http://subversion.tigris.org/, and the program should be available for Windows, Linux, MacOS X, and many more platforms. Getting the Source for The First Time Once Subversion client is installed, we can use these commands to initially retrieve the latest sources from the Subversion trunk: $ svn co http://svn.pjproject.net/repos/pjproject/trunk pjproject $ cd pjproject Keeping The Local Copy Up-to-Date Once sources have been downloaded, we can keep the local copy up to date by periodically synchronizing the local source with the latest revision from the PJ's Subversion trunk. The mailing list provides best source of information about the availability of new updates in the trunk. To update the local copy with the latest changes in the main PJ's repository: $ cd pjproject $ svn update Tracking Local and Remote Changes To see what files have been changed locally: $ cd pjproject $ svn status The above command only compares local file against the original local copy, so it doesn't require Internet connection while performing the check. To see both what files have been changed locally and what files have been updated in the PJ's Subversion repository: $ cd pjproject $ svn status -u Note that this command requires active Internet connection to query the status of PJPROJECT's source repository. 1.3 Source Directories Layout _________________________________________________________________ Top-Level Directory Layout The top-level directories (denoted as $TOP here) in the source distribution contains the following sub-directories: $TOP/build Contains makefiles that are common for all projects. $TOP/pjlib Contains header and source files of PJLIB. PJLIB is the base portability and framework library which is used by all other libraries $TOP/pjlib-util
