Hi Benny, Iam using the PJSIP verion (pjproject-1.5.5). I tried to build PJSUA statically for arm processor. Then transferred the bin file pjsua-arm-unknown-linux-gnu (pjsip-apps/bin/) on to the target board (arm processor). While running ./pjsua-arm-unknown-gnu, immediately getting the segmentation fault. ./pjsua-arm-unknown-linux-gnu Segmentation fault Please give your suggestion and some clue to debug. i appreciate your valuable suggestion. Thanks, Prem -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20100219/a5f1de48/attachment-0001.html>
