netinet/in.h in OpenBSD 4.4 i386 broken?

[SunSpyda]

I'm trying to get socket programming to work, but it just won't do it. I've tried the same code on Linux and other *nix OSes, and it worked fine, but it just refuses to work on OpenBSD...

The faults occur within that header file. Let's take this *really* simple C code...

#include <netinet/in.h>
#include <stdio.h>
#include <sys/socket.h>

#define PORT 13

int main( void )
{
    int socket = socket( AF_INET, SOCK_STREAM, 0 );
    struct sockaddr_in address;

    address.sin_family = AF_INET;
    address.sin_port = PORT;

    puts( "\nInitialization complete.\n" );

    return 0;
}

As I said, this code works great on other *nix OSes, but not OpenBSD. It just chokes when processing the netinet/in.h file. Any ideas?

I'm using GCC by the way.

I hardly believe that this compiles anywhere, for one..

• You're naming your local variable socket.. it clashes with the name of the socket function.
• You populate a few elements of the sockaddr_in structure, but don't do anything with it.

#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>

#define PORT 13

int main( void )
{
    int sock = socket( AF_INET, SOCK_STREAM, 0 );
    struct sockaddr_in address;

    address.sin_family = AF_INET;
    address.sin_port = PORT;

    puts( "\nInitialization complete.\n" );

    return 0;
}

It should at least compile now, but it's not exactly doing much of anything...

Yeah, a stupid mistake on my behalf.. They should really be called server_fd on a server app, right?

I know that structs utterly pointless, as it isn't being used, but it shouldn't generate an error should it?

Hmmm, this still won't compile...

#include <netinet/in.h>
#include <stdio.h>
#include <sys/socket.h>
#include <sys/types>

#define PORT 13

int main( void )
{
    int sock = socket( AF_INET, SOCK_STREAM, 0 );
    struct sockaddr_in address;

    address.sin_family = AF_INET;
    address.sin_port = PORT;

    puts( "\nInitialization complete.\n" );

    return 0;
}

move sys/types.h before both sys/socket.h and netinet/in.h

Thanks a lot! That solved nearly all the issues I was having. Furthermore, I completely forgot that the ordering of the includes makes a difference, so thanks for reminding me
