Do you know what is wrong ?

You appear to be trying to embed perl into XS. I don't know of anyone ever having tried that, and I don't know why anyone *would* try that.
AFAIK, you only ever embed perl into a *C* program - and you do that only when you want to be able to run perl code in that C program.
If you want to run perl code from XS, you just do a callback to that perl code. Here is a simple Inline::C example based on an example in the perldoc perlcall documentation: 
use strict;
use warnings;

use Inline C => Config =>
    USING => 'ParseRegExp',
    BUILD_NOISY => 1;

use Inline C => <<'EOC';

void c_foo(void) {
 dSP;

 PUSHMARK(SP);
 call_pv("perl_foo", G_DISCARD|G_NOARGS);
}

EOC

c_foo();

sub perl_foo {
            print "PID is $$\n";
}

I see you've found that perlcall documentation. Note that it contains no attempts to embed a perl interpreter into the code.

(In case you're unaware of it, Inline::C and XS are essentially the same - it's just that Inline::C writes your XS file for you, then compiles the XS code and runs the script.)
