Socket Programming socket

Hello,

I actually try to make client-server program.
I'm using SCO OpenServer Release 5.0.0 and when I try to compile my code (by TELNET) I've got this error :
Quote:
Undefined first referenced
symbol in file
socket /usr/tmp/cca000Hf1.o
a.out: fatal error: Symbol referencing errors. No output written to a.out
I'm just using this simple code :
Quote:
#include <sys/types.h>
#include <sys/socket.h>
#include <sys/un.h>
#include <stdio.h>

#define ADDRESS "192.168.0.191"

char *strs[3] = {"Message test - Socket"};

main()
{
char c;
FILE *fp;
int fromlen;
register int i, s, ns, len;
struct sockaddr_un saun, fsaun;

if ((s = socket(AF_UNIX, SOCK_STREAM, 0)) < 0)
{
perror("server: socket");
exit(1);
}
exit(0);
}
and I get the same error if I use :
Quote:
gcc serv.c
or
cc serv.c
or
c++ serv.c
If someone can help me,
Thanks

NAME
ppmtopgm - convert a portable pixmap into a portable graymap SYNOPSIS
ppmtopgm [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b. Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original colors, not necessarily a way that looks like a black and white photograph. QUOTE
Cold-hearted orb that rules the night Removes the colors from our sight Red is gray, and yellow white But we decide which is right And which is a quantization error. SEE ALSO
