Hi, I have downloaded and installed Pjsip library on my linux machine. I tried to compile the following sample application at link, i got tons of error, http://www.pjsip.org/pjsip/docs/html/page_pjsip_sample_sipstateless_c.htm /tmp/ccw4XYym.o: In function `pj_list_push_back': sipstateless.c:(.text+0x29): undefined reference to `pj_list_insert_before' /tmp/ccw4XYym.o: In function `on_rx_request': sipstateless.c:(.text+0xec): undefined reference to `pjsip_endpt_respond_stateless' /tmp/ccw4XYym.o: In function `main': sipstateless.c:(.text+0x1c3): undefined reference to `pj_init' sipstateless.c:(.text+0x20e): undefined reference to `pjlib_util_init' sipstateless.c:(.text+0x264): undefined reference to `pj_pool_factory_default_policy' sipstateless.c:(.text+0x272): undefined reference to `pj_caching_pool_init' sipstateless.c:(.text+0x290): undefined reference to `pjsip_endpt_create' sipstateless.c:(.text+0x2dc): undefined reference to `pj_optind' sipstateless.c:(.text+0x337): undefined reference to `pj_pool_create' sipstateless.c:(.text+0x354): undefined reference to `pj_optarg' sipstateless.c:(.text+0x3b8): undefined reference to `pj_str' sipstateless.c:(.text+0x3eb): undefined reference to `pj_str' sipstateless.c:(.text+0x428): undefined reference to `pjsip_generic_string_hdr_create' sipstateless.c:(.text+0x449): undefined reference to `pj_log_get_level' sipstateless.c:(.text+0x476): undefined reference to `pj_log_4' sipstateless.c:(.text+0x4b3): undefined reference to `pj_getopt' sipstateless.c:(.text+0x4cb): undefined reference to `pj_optind' sipstateless.c:(.text+0x4d4): undefined reference to `pj_optind' sipstateless.c:(.text+0x524): undefined reference to `pj_log_get_level' sipstateless.c:(.text+0x546): undefined reference to `pj_log_4' sipstateless.c:(.text+0x54d): undefined reference to `PJ_AF_INET' sipstateless.c:(.text+0x564): undefined reference to `pj_htons' sipstateless.c:(.text+0x594): undefined reference to `pjsip_udp_transport_start' sipstateless.c:(.text+0x5a8): undefined reference to `pj_log_get_level' sipstateless.c:(.text+0x5c1): undefined reference to `pj_log_3' sipstateless.c:(.text+0x5d2): undefined reference to `PJ_AF_INET' sipstateless.c:(.text+0x5e9): undefined reference to `pj_htons' sipstateless.c:(.text+0x611): undefined reference to `pjsip_tcp_transport_start' sipstateless.c:(.text+0x625): undefined reference to `pj_log_get_level' sipstateless.c:(.text+0x63e): undefined reference to `pj_log_3' sipstateless.c:(.text+0x65f): undefined reference to `pjsip_endpt_register_module' sipstateless.c:(.text+0x6a7): undefined reference to `pj_log_get_level' sipstateless.c:(.text+0x6c0): undefined reference to `pj_log_3' sipstateless.c:(.text+0x6d5): undefined reference to `pjsip_endpt_handle_events' Please guide me how solve this?? I don't understated if something missing ??, Please find Attached code for reference. If anybody have sample application code in C/c++ please share.
