Hi all, I'm trying build pjsua on windows xp, with visual studio 2008 and i have a problem. I get rid of erros with includes and all libs, but after that I gets *Error 18 error LNK2019: unresolved external symbol "public: __thiscall CBaseRenderer::CBaseRenderer(struct _GUID const &,char const *,struct IUnknown *,long *)" (**??0CBaseRenderer@@QAE at ABU_GUID@@PBDPAUIUnknown@@PAJ at Z * <??0CBaseRenderer@@QAE at ABU_GUID@@PBDPAUIUnknown@@PAJ at Z>*) referenced in function "public: __thiscall NullRenderer::NullRenderer(long *)" (** ??0NullRenderer@@QAE at PAJ@Z* <??0NullRenderer@@QAE at PAJ@Z>* ) libpjproject-i386-win32-vc8-debug.lib Error 19 fatal error LNK1120: 1 unresolved externals ..\bin\pjsua-i386-Win32-vc8-Debug.exe * if I off video in config_site it works fine but without video. I don't understand what I'm doing wrong... To build pjsua with video I used this user guides: http://trac.pjsip.org/repos/wiki/Getting-Started/Windows/2.0-dev, and http://trac.pjsip.org/repos/wiki/Video_Users_Guide. I have this requirements - ffmpeg from http://www.pjsip.org/tmp/ffmpeg-dev-gcc4.zip - SDL 1.3 from http://www.libsdl.org/tmp/SDL-1.3.zip - Windows SDK from http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ff6467e6-5bba-4bf5-b562-9199be864d29 I change the code generation to Multi-threaded Debug in the property of the Baseclasses project, and add the include path to Visual Studio configuration. I include picture with my paths Visual Studio configuration (C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\Multimedia\DirectShow\BaseClasses) Regards Andrzej Grajnert -------------- next part -------------- An HTML attachment was scrubbed...
