Ok, this is a cross-posting from StackOverflow http://stackoverflow.com/questions/27058788/attempt-to-embed-perl-in-c-on-windows . I posted it there first because I thought it is more C than Perl question. However I did not get any answer and so I'd like to try it again.

I am trying to run the following example from http://perl-node-interface.blogspot.de/2011/03/deploy-perl-application-on-windows.html (is not accepted as link) with a simple "Hello.pl" (just prints "Hello" to STDOUT).

It fails. The .exe file is created but does not produce any output.

Probably this is my basic misunderstanding. Could you please point me in the right direction? Btw. the "lib folder containing all dependencies" in the project folder is empty since there are no modules in the "hello.pl". Is this a correct assumption?

Thank you very much!

The hello.c file:

#include <EXTERN.h>
#include <perl.h>

EXTERN_C void xs_init (pTHX);

EXTERN_C void boot_DynaLoader (pTHX_ CV* cv);
EXTERN_C void boot_Win32CORE (pTHX_ CV* cv);

EXTERN_C void
xs_init(pTHX)
{
  char *file = __FILE__;

   dXSUB_SYS;

   /* DynaLoader is a special case */
   newXS("DynaLoader::boot_DynaLoader", boot_DynaLoader, file);
   newXS("Win32CORE::bootstrap", boot_Win32CORE, file);
 }


static PerlInterpreter *my_perl;  /***    The Perl interpreter    ***/

int main(int argc, char **argv, char **env)
{
  argv[1] = "-Ilib";
  argv[2] = "hello.pl";
  PERL_SYS_INIT3(&argc,&argv,&env);
  my_perl = perl_alloc();
  perl_construct(my_perl);
  PL_exit_flags |= PERL_EXIT_DESTRUCT_END;
  perl_parse(my_perl, NULL, argc, argv, (char **)NULL);
  perl_run(my_perl);
  perl_destruct(my_perl);
  perl_free(my_perl);
  PERL_SYS_TERM();
}

The perl file to build the compiler command:

#!/perl
use strict;
use warnings FATAL => qw(all);

use ExtUtils::Embed;

print "\nBuilding Hello\n";
my $gcc_cmd = join( ' ' , 'C:\Perl_516_portable\c\bin\gcc -Wall -mwind
+ows -o K:\Scripts\Embed\Hello_3\hello K:\Scripts\Embed\Hello_3\hello.
+c',
&ccopts, &ldopts );

print STDOUT $gcc_cmd , "\n";
system( $gcc_cmd );
