Question

I have the following code that works on Linux but doesn’t work on Windows(VS2008)

URI(): Poco::URI::URI();

I get the following errors:

error C2039: '{ctor}' : is not a member of 'Poco::URI'
error C2437: 'URI': already initialized

I made the following changes to:

URI(){ Poco::URI::URI(); }

Do the two lines of code mean the same? And why doesn’t the first one line of code don’t work on Windows?

edit:
I am using the Poco Library, so this is code I have:

#include Poco/URI.h
class URI : public Poco::URI
{
public:
    URI(): Poco::URI::URI(){}
};

Poco/URI.h

namespace Poco {

class URI
{
public:
    URI::URI():
_port(0){}
private:
unsigned short _port;
};

The right way to do the following:

URI() : Poco::URI(){}

I was including a namespace URI that did not exist.

Also:

Poco::URI::URI(){} // works when using gcc compiler but not on a windows compiler
