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

I'm trying to add a log file using Log4perl to a final script. I'm packaging the script using perl2exe and when I go to run the file I get the error:
undefined value provided for log level at PERL2EXE_STORAGE/Log/Log4perl/Appender .pm line 77
Not sure where the error is happening. Here is the logger code:
use Log::Log4perl qw(:easy);
Log::Log4perl->easy_init($ERROR);
my $logger = get_logger();

# Appenders
my $appender = Log::Log4perl::Appender->new(
    "Log::Dispatch::File",
    filename => "grruvi.log",
    mode => 'trunc'
);
$logger->add_appender($appender);

# Layouts
my $layout = Log::Log4perl::Layout::PatternLayout->new("%d %p> %F{1}:%
+L %M - %m%n");
$appender->layout($layout);

my $timer_log = Glib::Timeout->add(100, \&log);

sub log {
    if (defined $!){
        if (length $! != 0 and length $! <= 30){
#            $log->error($!)
            $logger->error($!);
        }
    }
}

I really just want to log errors or maybe even warnings so that I can handle them later. I'm sure there is better code out there than what I have. thanks for the help!

    For what I've heard, perl2exe's use is deprecated.
    You sould try the PAR module (PAR module, which comes with a packing application, "pp").

    Read this for more information.

      true but, I have had trouble trying to package GTK2 programs using pp in the past. Has that changed?

    Are you sure that the script runs from the command line at all, without using perl2exe? Couple of things to watch out for:

    First, I wouldn't recommend naming a function "log()", since log is a built-in. Use a different name and run the script from the command line to make sure nothing else is causing a problem.

    Secondly, you probably need to tell perl2exe that you're using Log::Dispatch::File, as it's probably not smart enough to tell that by looking at the code, since you're not "use"ing it but letting Log4perl require it at runtime.

    Thirdly, I would recommend using Log4perl's native file appender (comes with Log4perl), Log::Log4perl::Appender::File.

    Fourthly, there's nothing wrong with your configuration, but you probably want to use a Log4perl configuration file (or string!) to keep things nice and clean and in one place.
