Hey folks... I've tried building this module with h2xs | (swig & (MakeMaker | ModuleBuild)). It builds and is installed fine, but when i go to use it in a test script, i get this error message:

Can't find 'boot_MappedMaps' symbol in /.../MappedMaps.so at /.../MappedMaps.pm line 7 Compilation failed in require at testMappedMaps.pl line 7. BEGIN failed--compilation aborted at testMappedMaps.pl line 7.

Here's the MakeMaker Makefile.PL:

use 5.008003;
use ExtUtils::MakeMaker;
$CC = 'g++';
WriteMakefile (
    NAME    => 'MappedMaps',
    VERSION => '0.1.0.0', 
    LDFROM  => './MappedMaps.o', 
    LIBS    => ['-lgcc_s'], 
    DEFINE  => '-Dcplusplus', 
    INC     => '-I. -I/usr/include -I/usr/include/g++', 
    CC      => $CC,
    LD      => $CC
);

Also, here's the swig cmd-line and the h2xs cmd-line:

#swig -perl -c++ -Fstandard -v -Wall -I$(TOP_SRCDIR)/common -I/usr/inc
+lude MappedMaps.i

 #h2xs -F'-Dcplusplus -I/usr/include/g++' MappedMaps.h -lgcc_s

I understand DynaLoader (i've got the latest & greatest) is responsible for the bootstrapping, so what's going wrong here? How can I correct it? I'd be happy to provide more details if needed...much thanks in advance! _{janitored by ybiC: Balanced <code> tags around swig and h2xs command line examples, as per consideration.} -----------------------UPDATE--------------------------- ok, found the define where swig defines the following func. inside the swig _wrap code:

#define SWIG_init    boot_MappedMaps
[download]

then, the definition for SWIG_init is:

XS(SWIG_init) {
    dXSARGS;
    int i;
    static int _init = 0;
    if (!_init) {
        for (i = 0; swig_types_initial[i]; i++) {
            swig_types[i] = SWIG_TypeRegister(swig_types_initial[i]);
        }    
        _init = 1;
    }
    
    /* Install commands */
    for (i = 0; swig_commands[i].name; i++) {
        newXS((char*) swig_commands[i].name,swig_commands[i].wrapper, 
+(char*)__FILE__);
    }
    
    /* Install variables */
    for (i = 0; swig_variables[i].name; i++) {
        SV *sv;
        sv = perl_get_sv((char*) swig_variables[i].name, TRUE | 0x2);
        if (swig_variables[i].type) {
            SWIG_MakePtr(sv,(void *)1, *swig_variables[i].type,0);
        } else {
            sv_setiv(sv,(IV) 0);
        }
        swig_create_magic(sv, (char *) swig_variables[i].name, swig_va
+riables[i].set, swig_variables[i].get); 
    }
    
    /* Install constant */
    for (i = 0; swig_constants[i].type; i++) {
        SV *sv;
        sv = perl_get_sv((char*)swig_constants[i].name, TRUE | 0x2);
        switch(swig_constants[i].type) {
            case SWIG_INT:
            sv_setiv(sv, (IV) swig_constants[i].lvalue);
            break;
            case SWIG_FLOAT:
            sv_setnv(sv, (double) swig_constants[i].dvalue);
            break;
            case SWIG_STRING:
            sv_setpv(sv, (char *) swig_constants[i].pvalue);
            break;
            case SWIG_POINTER:
            SWIG_MakePtr(sv, swig_constants[i].pvalue, *(swig_constant
+s[i].ptype),0);
            break;
            case SWIG_BINARY:
            SWIG_MakePackedObj(sv, swig_constants[i].pvalue, swig_cons
+tants[i].lvalue, *(swig_constants[i].ptype));
            break;
            default:
            break;
        }
        SvREADONLY_on(sv);
    }
    
    SWIG_TypeClientData(SWIGTYPE_p_UGA_CAGT_PGML__MappedMaps, (void*) 
+"MappedMaps::MappedMaps");
    ST(0) = &PL_sv_yes;
    XSRETURN(1);
}

still have the question, "why can't DynaLoader find boot_MappedMaps?" anybody?
