Hi All,

I have used swig as interface btw perl and c++ world. There are 2 c++ functions which are invoked from the interface file. I then create a .o and .so files and finally run the perl file.

VIP2vera_interface is the interface class in which c++ functions are declared and the header file is below: 
class VIP2vera_interface
{
    public:

    VIP2vera_interface();
    ~VIP2vera_interface();        
    void  _getUserInfo ( char *userInfo );
    void  _fileDirCheckAndParserCall (char *userInfo);
};

[download]

_getUserInfo , _fileDirCheckAndParserCall are used to call the 2 c++ functions respectively.

I then do

1. g++ -m32 -lfl -shared AHB_Class.o vip2vera_interface_wrap.o -o vip2vera_interface.so -ldl $EXPAT_LIB

vip2vera_interface.so is created.

2. perl vip2vera_interface.pl

error:

perl: relocation error: ./vip2vera_interface.so: undefined symbol: _ZN18VIP2vera_interfaceC1Ev

AHB_Class is where the 2 functions are defined. where am i going wrong? Please help!
