hi, i am sorry to say that i dont have any experience in blackfin or uclinux. i answared you qustion because of: ? http://docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:asterisk ? so why not pjsip ? ? best of luck. TOWHID Hi as i said earlier - i found it in runtime files (something like /opt/uclinux/bfin-uclinux/runtime/usr/include) also found in uClinux-dist/linux-2.6.x/include. Now this (socket part) compiles well, but still have a problem with open-ssl for Blackfin. if you have an experience with blackfin please contact me directly (because it's no pjsip problem yet) if you want ;) Good luck -------------- next part -------------- An HTML attachment was scrubbed...
