Hi, Environment used: * Windows 2000 professional SP4 * Microsoft Visual C++ 2005 (including Express edition) * Microsoft Platform SDK 3790.1830 * Microsoft DirectX SDK 9.0 * Microsoft .NET framework 2.0 I've downloaded "pjproject-1.1.zip" from pjsip.org. Then I followed the instructions given under the following link: http://www.pjsip.org/using.htm#svn As mentioned under the section 4.2 I tried to build the "pjsua" project using Visual C++ compiler, but I received nearly 18 errors.
