Hi! I have version 5.005_03 and I'm using the Win32 version of the Learning Perl book.
I'm having trouble running a few scripts. For example, when I run the following:
Exercise 16.1
foreach $host (@ARGV) {
($name, $aliases, $addrtype, $length, @addrs) = gethostbyname($host);
print "$host:\n";
foreach $a (@addrs) {
print join(".", unpack("C4", $a)), "\n";
}
}
....I get the following errors:
Name "main::name" used only once: possible typo at 415.pl line 5.
Name "main::length" used only once: possible typo at 415.pl line 5.
Name "main::aliases" used only once: possible typo at 415.pl line 5.
Name "main::addrtype" used only once: possible typo at 415.pl line 5.
What am I doing wrong? The scripts in the book are supposedly for this version but I'm
having trouble with this and similar scripts. Also, I cannot get the
"IO::Sockets::INET->new" line to work in any of my scripts to run ("Unknown Error").
Any advice? Thanks! :-)
