Compilation issue: aggregate 's_toto reply' has incomplete type and cannot be defined

iTom

Hello everyone ;-)

I am trying to compile this code but I have very strange issue:
erreur : aggregate 's_toto reply' has incomplete type and cannot be defined

It look's like generate a structure which have a incomplete type. I didn't know that thing exist ^^.

The problem occur when I try to declare "reply" of "s_toto" type which is a structure declared in "MessagesFromClientToServer.h"

This is my code:
Client.cpp:

Client::Client(QTcpSocket * p_client, QObject * parent) : QThread(parent)
{
    // Declaration
    s_toto reply;
}

Client.h include "MessagesFromClientToServer.h"

MessagesFromClientToServer.h:

// Message from Server to Client to reply the request
struct {
    unsigned int magic;
    unsigned int type;
    unsigned int server_version;
    unsigned int min_client_version;
    bool client_version_OK;
    bool client_pseudo_OK;
    bool nothing;
    unsigned int stop;
} toto;
typedef struct toto s_toto;

My compiler error:

client.cpp:12:12: error: aggregate 's_toto reply' has incomplete type and cannot be defined s_toto reply;

Have you an idea how to fix it ?

Thank you in advance ;-)

My advice is to give a name to your structure. Something like this:

struct toto {
    // ...
};

@iTom To add to @kshegunov : did you include MessagesFromClientToServer.h header file where you're trying to use it?
