I'm trying to run a simple program with osip2 library version 5.0.0. This is my code, and i'm having some errors that i cant figure out. I'm using codeblocks.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <osip2/osip.h>
#include <osipparser2/osip_parser.h>
#include <string.h>
#include <winsock2.h>
int main() {
int i; osip_t *osip; i=osip_init(&osip); if (i!=0) return -1; }

the errors showing this part of code in library:
struct osip_ict {
int timer_a_length; /**< Timer A A=T1, A=2xT1... (unreliable only) */
struct timeval timer_a_start; /**< Timer A (retransmission) */
int timer_b_length; /**< Timer B B = 64* T1 */
struct timeval timer_b_start; /**< Timer B (fire when transaction timeout) */
int timer_d_length; /**< Timer D D >= 32s for unreliable tr (or 0) */
struct timeval timer_d_start; /**< Timer D */
char *destination; /**< IP used to send requests */
int port; /**< port of next hop */
};
The structure timeval is not a standard C structure, it originated in the Unix world and is standardized in POSIX.
On Windows it's defined in the <winsock2.h> header file (because it's used by the select "network" function, see this struct timeval reference on MSDN for more information).
Since you include <winsock2.h> after the structure is used in <osip2\osip.h>, you get the error. The simplest solution is to rearrange the order of your include files.
