require "sys/socket.ph";

Dear All,

I am facing one problem if any body knows the solution please let me know.



file name : ch.pl..

use Socket;

require "sys/socket.ph";    # for &TCP_NODELAY

socket (SERVER,  AF_INET, SOCK_STREAM,0); setsockopt(SERVER, SOL_SOCKET,
&TCP_NODELAY, 1)

or die "Couldn't disable Nagle's algorithm: $!\n";





when the file is compiled, it's throwing error like this..

Scalar found where operator expected at (eval 148) line 1, near "'int'

$__val"

(Missing operator before   $__val?)

Undefined subroutine &main::__LONG_MAX__ called at (eval 316) line 1.

Compilation failed in require at

/usr/lib/perl5/5.8.1/i386-linux-thread-multi/sys/socket.ph line 11.

Compilation failed in require at ch.pl line 2.



Thanks in Advance



Thanks & Regards

-Gayatri

^^^^^^^^^^^^^^^^^^^^^^^^^^

Remove that line and it should work (TCP_NODELAY is included in the Socket
module.)

Well John Krahn probably gave you the answer, but just in case,
read "man h2ph" and/or "perldoc h2ph".

It explains how you can run the h2ph command to convert
your systems .h files to perls .ph files.
