hello! sorry, for late reply. as I can see - you have problems in pjsua and pjmedia_test projects. let's concentrate on pjsua. in my solution(under 2005 VS) for pjsua I have next configuration: C/C++\General\ Additional Include Directories ../../pjsip/include,../../pjlib/include,../../pjlib-util/include,../../pjmedia/include,../../pjnath/include Linker\ General\ Additional Library Directories D:\Projects\PJSIP\_BaseClasses\Debug\; "C:\Program Files\Microsoft SDKs\Windows\v6.0\Lib\"; "D:\Projects\PJSIP\SDL-1.3.0-6091\VisualC\SDL\Release\"; "D:\Projects\PJSIP\ffmpeg-git-7d531e8-win32-dev\lib\"; "C:\Program Files (x86)\Microsoft DirectX SDK (March 2009)\Lib\x86\" BUT you post that you link libraries : DIRECTX, FFMPEG, SDL, DIRECTSHOW to your pjsua project. I think you should: 1. Change order of include libraries according to my example 2. Add include of PSDK Vista to your project. (in my case is "C:\Program Files\Microsoft SDKs\Windows\v6.0\Lib\";) if you like - send me in private e-mail some FTP settings and I share with you my PSDK Vista. 3. Also check these configuration og pjsua Linker\ Input \ Additional Dependencies Iphlpapi.lib dsound.lib dxguid.lib netapi32.lib mswsock.lib ws2_32.lib odbc32.lib odbccp32.lib ole32.lib user32.lib gdi32.lib advapi32.lib Ingnore All Default Libraries No Ignore Specific Library msvcrt.lib; LIBCMTD.lib (for debug) -------------- next part -------------- An HTML attachment was scrubbed...
