<P><FONT SIZE=2>Hi,<BR>
<BR>
Please point me where I am doing mistake or missing something.<BR>
<BR>
I created a simple example to understand the bit and bytes of py++<BR>
<BR>
<BR>
cpp header file afile.h<BR>
=========================<BR>
class box{<BR>
public:<BR>
box(int , int );<BR>
int area(box &obj);<BR>
<BR>
private:<BR>
int length;<BR>
int width;<BR>
};<BR>
=========================<BR>
<BR>
cpp source file afile.cpp<BR>
=========================<BR>
#include"afile.h"<BR>
#include<iostream><BR>
<BR>
box::box(int x, int y):length(x),width(y)<BR>
{<BR>
}<BR>
<BR>
int box::area(box &obj){<BR>
return obj.length * obj.width;<BR>
}<BR>
<BR>
using namespace std;<BR>
<BR>
int main()<BR>
{<BR>
box p(10, 20);<BR>
int a;<BR>
a=p.area(p);<BR>
<BR>
std::cout<<"Area is "<<a<<"\n";<BR>
return 0;<BR>
}<BR>
======================<BR>
<BR>
py++ code afile.py<BR>
========================<BR>
import os<BR>
from pyplusplus import module_builder<BR>
from pyplusplus.module_builder import call_policies<BR>
<BR>
mb=module_builder.module_builder_t([r"/home/vbayskar/exPy/afile.cpp"])<BR>
<BR>
<BR>
mb.free_function('area').call_policies = call_policies.default_call_policies()<BR>
<BR>
mb.build_code_creator( module_name = 'testModule')<BR>
<BR>
mb.write_module('./testModule')<BR>
==========================<BR>
<BR>
and when I run this python file afile.py<BR>
<BR>
it gives the following error<BR>
============================<BR>
/usr/lib/python2.4/site-packages/pygccxml/parser/scanner.py:337: UserWarning: unable to find out array size from expression ""<BR>
warnings.warn( msg )<BR>
Traceback (most recent call last):<BR>

File "/usr/lib/python2.4/site-packages/pygccxml/declarations/matcher.py", line 79, in get_single<BR>
raise matcher.declaration_not_found_t( decl_matcher )<BR>
pygccxml.declarations.matcher.declaration_not_found_t: Unable to find declaration. matcher: [(decl type==free_function_t) and (name==area)]<BR>
===========================<BR>

<BR>
Thanks<BR>
