dear Authority, This is to bring to your kind attention that i am currently building a desktop MFC application by including your pjsip version 1.4.5. I have included every thing as descried in your web side but its a matter of regret that when i tried to build my application in static build that time i got \pjmedia\src\pjmedia-codec\ipp_codecs.c(41) : fatal error C1083: Cannot open include file: 'ippversion.h': No such file or directory . Please help me out of this problem. With Regards Liton -------------- next part -------------- An HTML attachment was scrubbed...
