Calling a subroutine using $ENV{'DOCUMENT_ROOT'}

[TimmyC]

I'm having trouble calling my subroutines with a variable.

My website is hosted on a virtual server; as such my absolute path on the server is subject to change from time to time. The company provided the following environment variable for use when a CGI script calls for my absolute path:

$ENV{'DOCUMENT_ROOT'}

I am trying to use a scalar variable as the argument for the require function.

I set up the following scripts to call a subroutine. When I run the script I get an error message saying the document contains no data.

Here's the main script:

#!/usr/local/bin/perl -wT
print "Content-type: text/html\n\n";
use strict;
use CGI ':standard';

my $path = qq($ENV{'DOCUMENT_ROOT'}cgi/library.lib);

require qq($path);

test();

Here's the library script:

sub test{

print qq(Hello, it works.);
}

1;

You can view the error message at

Does anyone know why this won't work?

NOTE: I printed the $path variable, then I cut and pasted it from the screen, and used that for the require argument and it worked fine.
