I'm trying to compile the simplest snippet I can using pp with Strawberry Perl on Windows tp submit threads.

The code runs just fine with just loose perl

Running "pp -x ThreadTest.pl -o ThreadTest.o" runs just fine and creates an exe file.

Running the resulting executable fails every time.

Parent reports child. Child reports in and runs, then fails as last child code exits.

If run with multiple threads, all submit, all check in, all seem to exit, then it errors out.

How can we compile code with threads for windows? Is it a perl problem or a Windows problem?

#Hash of Child PIDs
our %ChildPids;

#my $MaxThreadsAtOneTime = 5;
#my $MaxThreadsAtOneTime = 2;
my $MaxThreadsAtOneTime = 1;
my $ThreadsToRun = 50;

#### MAIN

# Submit first group of children
print("Submitting first batch of children\n");
my $ThreadNum = 0;
while (($ThreadNum < $MaxThreadsAtOneTime) &&
       ($ThreadNum < $ThreadsToRun)) {
    $ThreadNum++;
    my $ChildPid;
    if ($ChildPid = fork) {    
        # parent code
        # Collect pid
        print("Parent found Child $ThreadNum with pid $ChildPid\n");
        $ChildPids{$ChildPid} = $ThreadNum;
    } elsif (defined $ChildPid) {
        # child code
        print("     Child pid $$ checking in as thread $ThreadNum\n");
        my $SleepTime = int(rand(30));
        print("     Child pid $$ sleeping for $SleepTime seconds\n");
        sleep $SleepTime;
          print("     Child pid $$ exiting\n");
        exit();
    }
}
