Hi All, I managed to build pjsua2.dll and pjsua2.so To build the dll , I've used with cygwin as described in book with these options : ./configure --target=i386 The generated pjsua2.so is well working on Linux station, however the pjsip2.dll is not working on windows 7 station. The dll is well loaded by java application but when I intialized an Object such Endpoint, there is no output and the application is going down . Does any one meet the same issue ? Any help, is well appreciated. Thanks in advance Akram -------------- next part -------------- An HTML attachment was scrubbed...
