[Serusers] Problem in exporting function

Hello all,
I am very new to ser
I am using 8.14 version of ser ... I build up ser from source code
available from CVS repositry.
Actually I wanted to make a simple module for logging of Source name and
host name that passes through ser (just for learning purpose) ...... I build
up the module and placed it in ser's source module directory and recompiled
the source .....Now problem is that when I try to call one exported function
from ( i.e. siplog) from ser.cfg .... It gives me following error message
......
0(12672) parse error (89,8-9): unknown command, missing loadmodule?
when I did ser -dd -c I got following
0(14407) find_export: <siplog> not found
0(14407) find_export: <siplog> not found
0(14407) parse error (90,9-10): unknown command, missing loadmodule?
So I think siplog() is not exported ....... could not find the reason why it
is so because I am exporting it ...........
My source code is following -----
#include "../../sr_module.h"
#include <stdio.h>
char * str_param;
int int_param;
MODULE_VERSION
static int mod_init(void) ;
static int siplog(struct sip_msg *msg,char *str,char *str2);
static int mod_init(void) {
fprintf(stdout,"initializing siplog module");
return 0;
}
static cmd_export_t cmds[] = {
{"siplog",siplog,1,0,REQUEST_ROUTE},
{0,0,0,0,0}
};
struct module_exports exports = {
"siplog", /*module name */
cmds, /*cmd-name registered by this module */
0,
mod_init,
0,
0,
0,
0
};
static int siplog(struct sip_msg*msg,char*str,char*str2) {
/*the basic logic of module goes here*/
}
My ser.cfg file is as follows---

if (uri==myself) {

# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
};
append_hf("P-hint: usrloc applied\r\n");
route(1);
}
route[1]
{
# send it out now; use stateful forwarding as it works reliably
# even for UDP2TCP
if (!t_relay()) {
sl_reply_error();
};
}
I would be very thankful for any kind of help ....
Thanks
