following excerpt from perldoc perlembed is for you:

  Using Perl modules, which themselves use C libraries, from your C pr
+ogram
    If you've played with the examples above and tried to embed a scri
+pt
    that *use()*s a Perl module (such as *Socket*) which itself uses a
+ C or
    C++ library, this probably happened:

     Can't load module Socket, dynamic loading not available in this p
+erl.
      (You may need to build a new perl executable which either suppor
+ts
      dynamic loading or has the Socket module statically linked into 
+it.)

    What's wrong?

    Your interpreter doesn't know how to communicate with these extens
+ions
    on its own. A little glue will help. Up until now you've been call
+ing
    *perl_parse()*, handing it NULL for the second argument:

     perl_parse(my_perl, NULL, argc, my_argv, NULL);

    That's where the glue code can be inserted to create the initial c
+ontact
    between Perl and linked C/C++ routines. Let's take a look some pie
+ces of
    *perlmain.c* to see how Perl does this:

     static void xs_init (pTHX);

     EXTERN_C void boot_DynaLoader (pTHX_ CV* cv);
