[SR-Users] Reg. shared library linking during compiling time

Hello All, Please find below steps...and kindly let me know the error solution. STEP 1:: Under modules I created a directory name b2bentities /root/kamailio-3.3.2/modules/b2bentities $ls b2bentities.so b2b_server.c b2b_server.d b2b_server.h b2b_server.o dialog.h librpath.lst makecfg.lst Makefile In b2b_server.h #ifndef SERVER_H #define SERVER_H #endif int b2b_dlg_reply(); In b2b_server.c I wrote following code :: int b2b_dlg_reply() { LOG(L_INFO,"Hello am in b2bua module\n"); return 0; } Also,I added below code to the same file as per steps given in kamailio server's developer's guide. In developer's guide,they told to initialize parameters as per module's requirement but i made them all empty and null... for example static int mod_init(void) { LOG(L_INFO,"IN mod_init\n"); return 0; } static cmd_export_t commands[] = { }; static param_export_t params[]={ }; struct module_exports exports = { "b2bentities", // module name NULL, // dlopen flags commands, // exported functions params, // exported parameters NULL, // exported statistics NULL, // exported MI functions NULL, // exported pseudo-variables NULL, // extra processes mod_init, // module init function (before fork. kids will inherit) NULL, // reply processing function NULL, // destroy function child_init // child init function }; STEP 2:: In kamailio core file : In receive.c Method Name : In receive_msg i did this way... In receive.c add follow piece of code:: #include "modules/b2bentities/b2b_server.h" int receive_msg(....) { /*my code*/ int b2b_ret; int (*ptr)(); ptr= b2b_dlg_reply; if(msg->REQ_METHOD!=METHOD_REGISTER) { b2b_ret=(*ptr)(); if(b2b_ret!=0) { LOG(L_INFO,"B2B Dialogue reply function failed\n"); exit(1); } else { LOG(L_INFO,"B2B Dialogue reply function success\n"); exit(1); } } } STEP 3:: I even added kamailio.cfg load module "b2bentities.so" STEP 4:: Final step,when I do make all..... its giving me the following error :: [root@kamserver kamailio-3.3.2]# make all CC (gcc) [kamailio] receive.o LD (gcc) [kamailio] kamailio receive.o: In function `receive_msg': /root/kamailio-3.3.2/receive.c:163: undefined reference to `b2b_dlg_reply' collect2: ld returned 1 exit status make: *** [kamailio] Error 1 My doubt: Where should my b2bentities.so should be linked during compiling time? Please tell me the steps for it. Thanks & Regards, Manjusha A. Integra Micro Software Services (P) Ltd.
