I think that the problem resides with the "END" directive.
but I don't understand where I should use it and how.
Can you please take a quick glance at the following code ?
Thanks, Nir

=head1 NAME

NewModule - Perl extension for blah blah blah

=head1 SYNOPSIS

  use NewModule;
  blah blah blah

=head1 DESCRIPTION

Stub documentation for NewModule, created by h2xs. It looks like the
author of the extension was negligent enough to leave the stub
unedited.

Blah blah blah.

=head2 EXPORT

None by default.



=head1 SEE ALSO

Mention other useful documentation such as the documentation of
related modules or operating system documentation (such as man pages
in UNIX), or any relevant external documentation such as RFCs or
standards.

If you have a mailing list set up for your module, mention it here.

I still think there's too many unknowns for us to be of much help. What happens when you run the following script (called try.pl):

use strict;
use warnings;
use Inline CPP => <<'EOC';
#include "main.h"
   int CCC;
   char GlobalArr[13] = {'G','l','o','b','a','l',' ','a','r','r','a','
+y','\0'};
   MyClass  myGlobalInstance(GlobalArr) ;
   int add(int x, int y) 
   {
      char arr[7]={'i','n',' ','a','d','d','\0'};
      MyClass mc(arr);
      myGlobalInstance.wow();
      return x + y;
  }
EOC

print add(7, 5);
[download]

For me, I get the following fatal errors:

try_pl_13b2.xs:15:18: main.h: No such file or directory
try_pl_13b2.xs:18: error: `MyClass' does not name a type
try_pl_13b2.xs: In function `int add(int, int)':
try_pl_13b2.xs:22: error: `MyClass' was not declared in this scope
try_pl_13b2.xs:22: error: expected `;' before "mc"
try_pl_13b2.xs:23: error: `myGlobalInstance' was not declared in this 
+scope
dmake:  Error code 129, while making 'try_pl_13b2.o'
[download]

But then I don't have 'main.h' so at least some of those failures are not surprising.

If I ever find out what 'main.h' contains (and where it is located), why/if those 'use lib' directives are necessary, and why/if those 'use Inline CPP => Config' parameters are necessary, then I might be able to offer better help. (And the same might hold for others, too. I'm actually fairly hopeless when it comes to C++, and I hope it remains that way ... so you might not get much help from me, in any event :-)

One thing I did notice which I think is almost certainly incorrect is:

use Inline CPP => Config => INC => '-l/users/nirf/perlTrials/inlineExa
+mple';

Did you mean:

use Inline CPP => Config => INC => '-I/users/nirf/perlTrials/inlineExa
+mple';

Hi Rob, from the cpp and header I created a shared object. Than I called that shared oblect from test.pl file. The test.pl file checks that the shared object is ok (and it worked). Than I wanted to have the same thing inside a pm file (and it just does't go for me). And this is the reason for my current problems. As i sad, wjen calling that shared object from a simple pl file everything works fine. The output of the pl file is -------------------outout of test.pl----------------
