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

Hi All,

I am new to Perl and experimenting static linking of modules in Perl. I have compiled a Perl without support for dynamic loading.

Normally I link any modules using xs_init call. Say If I were to load a module Filter::Util::Call, I will create a entry within xs_init function, which in turn is passed as argument to perl_parse.

xs_init(pTHX) { 
char *file = __FILE__; 
dXSUB_SYS; 
newXS("Filter::Util::Call::bootstrap",
       boot_Filter__Util__Call,file); 
}

PerlInterpreter *my_perl; 
#allocate memory for my_perl, construct my_perl, system initialization
+ 
... 
perl_parse(my_perl, xs_init, argc, args, loc_environ);

Now I am trying to use DB_File module. Seems like DB_File depends on AUTOLOAD. Is there a way where can I statically load DB_File module as shown above. Or am I missing something about DB_File.

    I think this is how you're supposed to do it 

    cd DB_File
perl Makefile.PL
make perl
make inst_perl

    now your static perl comes with DB_File

    Repeat for every module with XS components

      DB_File, GDBM_File, SDBM_File, ODBM_File and NDBM_File are core perl modules. But I noticed that only SDBM_File being installed. So I am trying to install rest of the modules manually. Any help is really appreciated

        But I am encountering few errors

        Listen to the error message :)

        GDBM_File.xs:7:18: error: gdbm.h: No such file or directory GDBM_File.xs:16

        LIBS => ["-lgdbm", "-ldbm"]

        GDBM_File is the perl interface to libgdbm, which you need to have installed if you wish to install GDBM_File

        DB_File, GDBM_File, SDBM_File, ODBM_File and NDBM_File are core perl modules. But I noticed that only SDBM_File being installed. So I am trying to install rest of the modules manually. Any help is really appreciated

        See AnyDBM_File, it explains, SDBM comes with perl (i'm sure other docs like READMEs explain this also), the rest are provided by the operating-system. You don't need all of them :)
