Config::IniFiles , all methods return fail?

Ahmet has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm testing Config::IniFiles module; this module working well before but now what happened, module methods are not running and returning fail...

Here is my example;

use Config::IniFiles;
$overlay = Config::IniFiles->new(-file => 'test.ini');
$overlay->newval("section1", "arg1", "anotherval");
$overlay->WriteConfig(-delta=>1);
[download]

Running... return "fail"

C:\Documents and Settings\...\Desktop>t.pl

Can't call method "newval" on an undefined value at C:\Documents and Settings\...\Desktop\t.pl line 3.

Ridiculous...

OS: Windows XP
Perl : v5.8.9 build 828
Config::IniFiles : v2.66

Regards. Ahmet,thank you...

The module fails to create an object. As a result `$overlay` is undefined. You should check the result of object creation and have a look at `@Config::IniFiles::errors` upon failure. `my $cfg = Config::IniFiles->new( -file => 'test.ini' ) or die "Failed to create Config::IniFiles object: @Config::IniFiles: +:errors\n";` [download] addendum: example: `0 linuxer@host /tmp $ cat /tmp/a.pl && perl /tmp/a.pl #! /usr/bin/perl use strict; use warnings; use Config::IniFiles; my $overlay = Config::IniFiles->new(-file => 'test.ini') or die "Failure: @Config::IniFiles::errors\n"; $overlay->newval("section1", "arg1", "anotherval"); $overlay->WriteConfig(-delta=>1); __END__ Failure: Empty file treated as error 255 linuxer@host /tmp $` [download]	[reply] [d/l] [select]

Hmm interesting because i'm 5 years programmer... (my head is not in place :)) C:\Documents and Settings\...\Desktop>t.pl Failed to create Config::IniFiles object: Empty file treated as error I understand... Ok running now, no problem... "-allowempty => 1" <= including parameter to "new" method and entering value is "1" and allowing "empty file"... Thank you very much linuxer . Regards.	[reply]

Maybe the test.ini file got messed up. Any way to determine why new returns undef?	[reply]
