in reply to perl ?compiler?

What program? Is it something you wrote or something you got somewhere else?

It's possible that everything is working fine, if you're running a program that does not produce output. I can't imagine why a program would produce no output if it was meant to be run from the command line, but it's possible. And if you're new to Perl and writing a simple program, you might just have forgotten to write anything, or perhaps are accidentally writing a blank variable. For example, this would produce no output without telling me I'd done something wrong due to my failure to use strict and use warnings:

#!/usr/bin/perl my $Nothing = "Hello World\n"; print $nothing;

Maybe try a simple test, like running

perl -e 'print "Hello!\n";'
from a command line, to confirm that Perl is OK and you can see output to your terminal.
