Hi Benny.. a couple of months ago I spent a lot of time trying to build the windows pjmedia.dll file; it should be very useful to put these istructions and steps in a chapter of the your documentation. Thanks so much for your work! cheers, andrea ----- Original Message ----- From: "Roland Klabunde" <roland.klabunde@xxxxxxxxxx> To: "pjsip embedded/DSP SIP discussion" <pjsip at lists.pjsip.org> Sent: Saturday, November 17, 2007 10:50 AM Subject: Re: Building pjsua as DLL Thank you Tom?s and Benny and have a nice weekend.

Thanks for clarifying this. In addition, if you're linking your application with the DLL version of the libraries, and if you have C or C++ application, you need to declare PJ_DLL macro (and not PJ_EXPORTING) in your application's project, to activate __declspec(dllimport) specifier in PJ's declarations. cheers, -benny Tom?s Valenta wrote: > Hi Roland, > yeah, this is an old recommendation.
