Hi everyone wanting a Win64 build of PJSIP! I just managed to build a working binary of PJSUA 2.0.1 in Visual Studio (2010). Here are the steps: 1. Add x64 solution platform. 2. Apply the patch attached (changes just three lines of code). 3. Disable SRTP (crashes in initialization), e.g. place #define PJMEDIA_HAS_SRTP 0 in config_site.h. 4. This is almost it, cross your fingers and try to build. 5. Turn off compiler optimizations at file third_party/g7221/decode/decoder.c if it crashes the compiler. 6. Define PJ_WIN32=1;PJ_M_X86_64=1; at project python_pjsua if necessary. Notice: This is "just works" solution, you get tons of warnings, clean solution will involve more issues, especially the fact that sizeof(void*)==sizeof(long) does not hold for Win64. Good luck, - Vali -------------- next part -------------- A non-text attachment was scrubbed...
