C++ compiler won't recognize a member function and a type

Question

Today it's the day of strange things.... Got a stupid hpp file and another stupid cpp file trying to implement a stupid class. Here they are:

// HPP

#ifndef _WFQUEUE_MANAGER_PROXY_HPP_
#define _WFQUEUE_MANAGER_PROXY_HPP_

#include <iostream>
#include <string>

#include "workflow.hpp"
#include "wfqueue.hpp"

//-----------------------------------------------------------------------------
// Enum, struct, aliases
namespace middleware {
typedef struct {
    std::string proxy_ipaddr; /* IP address to manager */
    std::string proxy_port; /* Port to manager */
} WFProxyConfig;
}
//-----------------------------------------------------------------------------
// Class definitions
namespace middleware {
/*!
 * This class provides network interface to access the workflow queue. It is
 * important to notice that constructor is private in order to let a factory
 * perform such a work.
 */
class WFQueueManagerProxy : public WFQueue {
    /*!
     * To let factory build properly this object, we provide access to every
     * part of it.
     */
    friend class WFQueueProxyFactory;
private:
    /*!
     * Privately constructs the object. Default configuration with loopback
     * address and invalid port.
     */
    WFQueueManagerProxy();
public:
    /*!
     * Destructor
     */
    ~WFQueueManagerProxy();
    /*!
     * Enqueues a workflow.
     */
    void enqueue(const Workflow& workflow);
    /*!
     * Dequeues a workflow.
     */
    const Workflow& dequeue();
private:
    /*!
     * Privately constructs the object. Assigning configuration.
     */
    void ConfigureProxy(WFProxyConfig conf);
    /*!
     * Parameters for proxy.
     */
    WFProxyConfig _config;
}; /* WFQueueManagerProxy */
} /* middleware */

#endif

Here the other

// CPP

#include "wfqueue_manager_proxy.hpp"

using namespace middleware;

//-----------------------------------------------------------------------------
// Constructors and destructor
/* Private constructor */
WFQueueManagerProxy::WFQueueManagerProxy() {
    (this->_config).proxy_ipaddr = "127.0.0.1";
    (this->_config).proxy_port = "0";
}
/* Destructor */
WFQueueManagerProxy::~WFQueueManagerProxy() {

}
//-----------------------------------------------------------------------------
// Public members
/* Enqueue */
void WFQueueManagerProxy::enqueue(const Workflow& workflow) {

}
/* Dequeue */
const Workflow& WFQueueManagerProxy::dequeue() {

}
//-----------------------------------------------------------------------------
// Private members
void WFQueueManagerProxy::ConfigureProxy(WFProxyConfig conf) {

}

Somebody please explain me why g++ tells me this:

wfqueue_manager_proxy.cpp: In constructor ‘middleware::WFQueueManagerProxy::WFQueueManagerProxy()’: wfqueue_manager_proxy.cpp:32: error: ‘class middleware::WFQueueManagerProxy’ has no member named ‘_config’ wfqueue_manager_proxy.cpp:33: error: ‘class middleware::WFQueueManagerProxy’ has no member named ‘_config’ wfqueue_manager_proxy.cpp: At global scope: wfqueue_manager_proxy.cpp:51: error: variable or field ‘ConfigureProxy’ declared void wfqueue_manager_proxy.cpp:51: error: ‘WFProxyConfig’ was not declared in this scope

ABSURD... It does not recognize that typedef and doesn't recognize a private member too... and, more than everything... why does not g++ recognize a member function trying to see it as a variable?????????

I have tried everything... PS (to who saw my earlier post): my virtual machine now is not the cause. I checked and got confirm that no virtual hard disk is corrupted or in collision with other virtual mem units.

Using stub Workflow and WFQueue classes this compiles fine for me using g++ 4.2.1 and clang++ 2.8. — Nate

Just a guess. Shouldn't it be

WFQueueManagerProxy::WFQueueManagerProxy() { 
    (this->_config).proxy_ipaddr = "127.0.0.1"; 
    (this->_config).proxy_port = "0"; 
}
