[Users] XMPP module: network.c file error

Hi! I'm trying to make xmpp module, to do this I'm configurating according to my file system several files (xmpp_component.c, util.c, xmpp.c ...). But I get error while compiling the file 'network.c'. I don't know where these errors come from because the rest of the files are OK. These are the errors and my 'network.c' file: Any help would be wellcomed. Izortze. network.c:27: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘<’ token network.c: In function ‘net_connect’: network.c:95: error: storage size of ‘sin’ isn’t known network.c:97: warning: implicit declaration of function ‘memset’ network.c:97: warning: incompatible implicit declaration of built-in function ‘memset’ network.c:97: error: invalid application of ‘sizeof’ to incomplete type ‘struct sockaddr_in’ network.c:98: error: ‘AF_INET’ undeclared (first use in this function) network.c:98: error: (Each undeclared identifier is reported only once network.c:98: error: for each function it appears in.) network.c:99: warning: implicit declaration of function ‘htons’ network.c:101: warning: implicit declaration of function ‘inet_aton’ network.c:104: warning: implicit declaration of function ‘DBG’ network.c:106: warning: implicit declaration of function ‘gethostbyname’ network.c:106: warning: assignment makes pointer from integer without a castnetwork.c:107: warning: implicit declaration of function ‘LOG’ network.c:107: error: ‘L_ERR’ undeclared (first use in this function) network.c:108: warning: implicit declaration of function ‘hstrerror’ network.c:108: error: ‘h_errno’ undeclared (first use in this function) network.c:111: warning: implicit declaration of function ‘memcpy’ network.c:111: warning: incompatible implicit declaration of built-in function ‘memcpy’ network.c:111: error: dereferencing pointer to incomplete type network.c:111: error: dereferencing pointer to incomplete type network.c:114: warning: implicit declaration of function ‘socket’ network.c:114: error: ‘PF_INET’ undeclared (first use in this function) network.c:114: error: ‘SOCK_STREAM’ undeclared (first use in this function) network.c:115: warning: implicit declaration of function ‘strerror’ network.c:115: error: ‘errno’ undeclared (first use in this function) network.c:119: warning: implicit declaration of function ‘inet_ntoa’ network.c:121: warning: implicit declaration of function ‘connect’ network.c:121: error: invalid application of ‘sizeof’ to incomplete type ‘struct sockaddr_in’ network.c:123: warning: implicit declaration of function ‘close’ network.c:95: warning: unused variable ‘sin’ network.c: In function ‘net_send’: network.c:137: warning: implicit declaration of function ‘send’ network.c: In function ‘net_printf’: network.c:149: error: ‘va_list’ undeclared (first use in this function) network.c:149: error: expected ‘;’ before ‘args’ network.c:152: warning: implicit declaration of function ‘va_start’ network.c:152: error: ‘args’ undeclared (first use in this function) network.c:153: warning: implicit declaration of function ‘vsnprintf’ network.c:154: warning: implicit declaration of function ‘va_end’ network.c:158: warning: implicit declaration of function ‘strlen’ network.c:158: warning: incompatible implicit declaration of built-in function ‘strlen’ network.c: In function ‘net_read_static’: network.c:166: warning: implicit declaration of function ‘recv’ network.c:168: error: ‘L_ERR’ undeclared (first use in this function) network.c:168: error: ‘errno’ undeclared (first use in this function) network.c:169: error: ‘NULL’ undeclared (first use in this function) make: *** [network.o] Error 1 /* * $Id: network.c 1827 2007-03-12 15:22:53Z bogdan_iancu $ * */ include <stdio.h> include <stdlib.h> include <string.h> include <unistd.h> include <stdarg.h> include <errno.h> include <sys/socket.h> include <netinet/in.h> include <arpa/inet.h> include <netdb.h> include "/usr/local/src/openser-1.2.0/sip-server/sr_module.h" int net_listen(char *server, int port) { int fd;
