Hi, I'm trying to set up a TLS transport on my WM 6 app built using PJSUA. I have installed the OpenSSL SDK for Windows. included the library files, - For Debug build: libeay32MTd and ssleay32MTd. - For Release build: libeay32MT and ssleay32MT. set PJSIP_HAS_TLS_TRANSPORT = 1 in config_site.h added a tls transport to my WM6 app "status = pjsua_transport_create(PJSIP_TRANSPORT_TLS, &tcp_cfg, &transport_id);" when compiled i get this error: Error 1 error LNK2019: unresolved external symbol pjsip_tls_transport_start referenced in function pjsua_transport_create pjsua_lib_wince.lib Error 2 fatal error LNK1120: 1 unresolved externals Windows Mobile 6 Professional SDK Any one can help? Thanks. Calvin -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20081016/bb342280/attachment.html>
