Re: Detect which version of perl an XS module is linked against?

in reply to Detect which version of perl an XS module is linked against?

You can load the xs extension using dlopen (or whatever windows has to realize that functionality - glib has g_module_open which allows to specify if symbols should be resolved lazily or not, so there has to be a way to do that on win32) and tell it to resolve all symbols non-lazily. If that fails it's probably due to some removed library.

Also I wonder why those extensions are linked against libperl. I thought those are loaded from perl/libperl. At least on my unix system I couldn't find a single extension linked to libperl.

    rafl,
    Thanks for the guidance but unfortunately I need a step-by-step tutorial. Other than Inline::C, I don't have a lot of experience embedding C in Perl nor do I have any experience developing native executables on Win32. Well, aside from what I can accomplish with MinGW and Visual Basic 5 (/me ducks).

    Update: Thanks. Given your reply below, I will work with the #parrot team as any solution needs to be accepted as a patch.

    Cheers - L~R

      DynaLoader provides a dl_load_file function, which will probably do what I said above, except you don't need c or anything.

      Also be sure to set the PERL_DL_NONLAZY environment variable to something true to force nonlazy binding.
