Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello monks.

I want to know if it's possible and how hard would it be to call functions from a C++ library(.so|.dll) from perl.

As I searched, a XS interface seems like the solution, but it's a rather big library(see CLAM) so I think do a interface for such a big library wouldn't be feasible.

Anyway, I decided to post this and ask for directions in what would be better in this case.

Thanks.

      I don't see how.
      Is there a way to specify external C++ files and I'm missing ?

      Besides that, it looks like this module actually compiles the code in runtime, which is totally impracticable in this case =/

        Yes: 
        use Inline Config =>
    INC => '-I/my/path',
    LIBS => '-L/your/path -lyourlib';

use Inline CPP => <<'END';
/* your C++ code */
END

# your perl code

        See the Inline::CPP documentation - and the Inline::C-Cookbook documentation (as the same principles apply to C++).

        Cheers,
        Rob

        It only compiles once. It reuses the previously compiled library if the code hasn't changed.

    I believe the purpose of h2xs is to automatically create XS code for a library.
