Hello! I just wanted to let you know that pjproject doesn't build when you set the following define: #define PJSIP_HAS_RESOLVER 0 This happens with the latest 2.0-rc and SVN trunk. I didn't check 1.14 but I figure the problem exists there as well. Build break happens in sip_resolve.c ( pjsip_resolve() ). The offending line is: 404: PJ_UNUSED_ARG(srv_name); Apparently srv_name doesn't exist. Commenting this out makes everything build again. Regards, Andreas
