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,

seems that you want to create your custom module. have you checked the
makefile of your module. in order to develop the custom module just copy
the existing module and make relevant changes there. this is genuine way
. for this u need to include makefile.lst ,Makefile in your module. so
best way is to copy the smallest module (e.g.) pdb module and make changes.
