Hi, I am using default seas configuration. When I tried to start openser seas module can not be loaded althoug module is compiled without problem. I tried 1.2.0 and 1.2.2 and the same problem occurred. It seems that it could not find "dprintf" function. How can I solve this problem? root@~: openser -ddddddddddd 0(43499) loading module /usr/local/lib/openser/modules/tm.so 0(43499) DEBUG: register_pv: tm 0(43499) xl_add_extra_spec: extra items list is not initialized 0(43499) xl_add_extra_spec: inserting extra item [T_branch_idx] at [0] 0(43499) xl_add_extra_spec: inserting extra item [T_reply_code] at [1] 0(43499) loading module /usr/local/lib/openser/modules/seas.so 0(43499) ERROR: load_module: could not open module </usr/local/lib/openser/modules/seas.so>: /usr/local/lib/openser/modules/seas.so: Undefined symbol "dprintf" and config is below Thanks, Kuddusi CIFTCIBASI. # ----------- global configuration parameters ------------------------ debug=9 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) children=4 # Uncomment these lines to enter debugging mode fork=no log_stderror=yes # reply_to_via=1 listen = tcp:84.51.32.24:5060 listen = udp:84.51.32.24:5060 port=5060 # ------------------ module loading ---------------------------------- #set module path #mpath="/usr/local/lib/openser/modules/" loadmodule "/usr/local/lib/openser/modules/tm.so" loadmodule "/usr/local/lib/openser/modules/seas.so" modparam("seas", "listen_sockets","84.51.32.24:5080") modparam("seas", "stats_socket","84.51.32.24:5088") #modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- # main routing logic route{ if(!as_relay_t("app_server_one")){ t_reply("500","No App Server"); } }
