Hey all,

I have a problem using a custom C-file. The error ouput received when compiling is given below.

error output
.../system.c:1330: undefined reference to `XML_ParserCreate'
...
.../system.c:1465: undefined reference to `sip_get_header'
...
.../system.c:1608: undefined reference to `pcap_lookupnet'
...


Before, I had all code in chan_sip.c. I want to transfer the code into a separate file (system.c) now. The dependencies given below MODULEINFO are customly set and worked fine when used in chan_sip.c. Can anyone figure out if something else has to be added somewhere? The code is quoted below:

sip.h
const char *sip_get_header(const struct sip_request *req, const char *name);

system.h
#include "asterisk/netsock2.h"

void ast_some_function(struct sip_pvt *p, struct ast_sockaddr *addr);

system.c
/*** MODULEINFO
        <depend>sqlite3</depend>
        <depend>expat</depend>
        <depend>pcap</depend>
        <support_level>extended</support_level>
***/

#include "asterisk/system.h"
#include "asterisk/sip.h"

void ast_some_function(struct sip_pvt *p, struct ast_sockaddr *addr)
{
    xmlParser = XML_ParserCreate(NULL);
   ...
ast_copy_string(touser, sip_get_header(req, "To"), strlen(sip_get_header(req, "To"))+1);
   ...
   pcap_lookupnet(pcapDev, &netp, &maskp, errbuf);
}

chan_sip.c
#include "asterisk/system.h"
#include "asterisk/sip.h"

ast_some_function(p, addr);


Thank you for any help!

Regards,
Juliannn
