The first thing to do is make sure that your version of Perl was compiled with thread support.

The output from perl -V on my system includes the following lines:

C:\pwe>perl -V Summary of my perl5 (revision 5 version 10 subversion 0) configuration +: Platform: osname=MSWin32, osvers=5.2, archname=MSWin32-x64-multi-thread uname='' config_args='undef' hint=recommended, useposix=true, d_sigaction=undef useithreads=define, usemultiplicity=define useperlio=define, d_sfio=undef, uselargefiles=define,
and also:
Characteristics of this binary (from libperl): Compile-time options: MULTIPLICITY PERL_DONT_CREATE_GVSV PERL_IMPLICIT_CONTEXT PERL_IMPLICIT_SYS PERL_MALLOC_WRAP PL_OP_SLAB_ALLOC USE_64_BIT_I +NT USE_ITHREADS USE_LARGE_FILES USE_PERLIO USE_SITECUSTOMIZE
Once you are satisfied that your Perl supports threads, you might want to compare your code with this snippet from one of my programs (which happily uses quite a few threads) and see if comparing it with your code might help.
foreach my $seq (0..$number-1) { my $doneflag = \$play_done[$seq]; $$doneflag = 0; $play_list[$seq] = threads->create(\&PlayoutThread, $doneflag, $target_list[$seq], $media_type, $portnum, $playouts); # Mark as already done if thread creation failed unless ($play_list[$seq]) { $$doneflag = 2; $play_errors++; } # Count it if thread creation succeeded else { $started++; } }

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
