Hi, I am building a Windows-based VoIP application with PJSIP 2.0. The design is very similar to Sipek VoIP project. The application works perfectly with the built-in codecs. As I needed the AMR-WB codec, I downloaded the trial version of Intel IPP 7.0. I have followed the instructions from http://trac.pjsip.org/repos/wiki/Intel_IPP_Codecs But I am getting the following link errors. Error 1 error LNK2001: unresolved external symbol _USC_G722_Fxns pjmedia-codec-i386-win32-vc8-release.lib pjsua_lib_wrapper Error 2 error LNK2001: unresolved external symbol _USC_G728_Fxns pjmedia-codec-i386-win32-vc8-release.lib pjsua_lib_wrapper Error 3 error LNK2001: unresolved external symbol _USC_G726_Fxns pjmedia-codec-i386-win32-vc8-release.lib pjsua_lib_wrapper Error 4 error LNK2001: unresolved external symbol _USC_G723_Fxns pjmedia-codec-i386-win32-vc8-release.lib pjsua_lib_wrapper Error 5 error LNK2001: unresolved external symbol _USC_G729AFP_Fxns pjmedia-codec-i386-win32-vc8-release.lib pjsua_lib_wrapper Error 6 error LNK2001: unresolved external symbol _USC_AMRWB_Fxns pjmedia-codec-i386-win32-vc8-release.lib pjsua_lib_wrapper Error 7 error LNK2001: unresolved external symbol _USC_GSMAMR_Fxns pjmedia-codec-i386-win32-vc8-release.lib pjsua_lib_wrapper Error 8 fatal error LNK1120: 7 unresolved externals c:\aviqa\GIT Backup\pjsua_lib_wrapper\build\\..\lib\pjsua_lib_wrapper.dll pjsua_lib_wrapper Error 9 The referenced assembly "c:\aviqa\GIT Backup\pjsua_lib_wrapper\lib\pjsua_lib_wrapper.dll" was not found. If this assembly is produced by another one of your projects, please make sure to build that project before building this one. The mailing list has similar queries put up, but not answered. Kindly help me out. -- Best Regards, Arjun P. Kamath -------------- next part -------------- An HTML attachment was scrubbed...
