Im having a problem doing something that I thought would be simple, but is
proving frustrating: I have a hash whose resulting values are variable names
(including the $ sign). I want to use these variables in my software, but am
unable to declare them. Here is a simplified sample code that tries to perform
the action that I need, but errors out:
#!C:\Perl\bin\perl.exe -w
use strict;
my %varHash;
$varHash{'test1'} = "\$hostnamevar";
print $varHash{'test1'} ."\n";
eval ("my $varHash{'test1'}");
$hostnamevar = "Hello World\n";
print "$hostnamevar\n";
exit 0;
Here is the error message:
Global symbol "$hostnamevar" requires explicit package name at C:\Documents
and Settings\TCohen\Desktop\junk.pl line 7.
Global symbol "$hostnamevar" requires explicit package name at C:\Documents
and Settings\TCohen\Desktop\junk.pl line 8.
Execution of C:\Documents and Settings\TCohen\Desktop\junk.pl aborted due to
compilation errors.
If I remove the use strict, then it works (but then I break good coding
principals).
Does anyone have a solution that I can use?
Thanks,
Tal
