Re: mixing classes c++ and xs with same name!

[Billy Patton]

Got it solved by changing my c++ class from Laff to LAFF.
Not much dev so far so it wasn't much trouble.
Thanks for reading.

 void            BuildLayerInfo(void);
 bool            Free(void);
};

class laff_db : public Laff
{
};
Previously the laff_db was a
typedef struct laff_db
{
char* path;
 cdmg_ht *cells;
 cdmg_ht * layer_info;
}
Doing the above lets me take baby steps in converting calls and functions 
from.
Laff * db.
LaffSomething(db)
db->Something();

Very good for slow conversion and testing of 17k lines of code. More before I 
switch to STL (string, lists, hash's)

Now the problems comes from the perl XS:
Here's my typemap :
Laff        T_PTROBJ
Laff::Node  T_PTROBJ
Laff::Cell  T_PTROBJ
Here's the top of my xs:
#ifdef __cplusplus
extern "C" {
#endif
#include <stdio.h>
#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
#ifdef __cplusplus
}
#endif
#include "Ui.h"
#include "ExCommand.h"
#include "my_string.h"
#include "Laff.h"
#include "xyArray.h"
using namespace std;
typedef node_t  * Laff__Node;
typedef cell_t  * Laff__Cell;
typedef laff_db * Laff;
MODULE = Laff       PACKAGE = Laff  PREFIX=Laff
PROTOTYPES: DISABLE
int
Laff_DESTROY(db)
 Laff db
CODE:
 RETVAL = LaffFree(db);
OUTPUT:
 RETVAL
I get the following error message at compile time:
Laff.c: In function `void XS_Laff__DESTROY(PerlInterpreter*, CV*)':
Laff.c:76: error: no matching function for call to `Laff::Laff(IV&)'
/data/cdmg/dev/cdmg_toolbox/Laff/Laff.h:453: note: candidates are: 
Laff::Laff(const Laff&)
/data/cdmg/dev/cdmg_toolbox/Laff/Laff.h:457: note: 
Laff::Laff()
Laff.xs:133: error: cannot convert `Laff' to `laff_db*' for argument `1' to 
`int LaffFree(laff_db*)'

It seems the clash of names between my c++ class Laff and the perl-xs class 
Laff are in comflict.  How can I resolve this?
