Public routines

[eltecprogetti]

I have a routine in my MainWindow, and I declared public this routine:


In MainWindow.cpp

void MainWindow::Read_Ambiente()
{
}

void MainWindow::Read_Ambiente()
{
}

To copy to clipboard, switch view to plain text mode 

In MainWindow.h

public:
    void Read_Ambiente();

public:
    void Read_Ambiente();

To copy to clipboard, switch view to plain text mode 

In another form I want to use this routine:

In Diagnostica.cpp

#include "mainwindow.h"
extern void Read_Ambiente();

#include "mainwindow.h"
extern void Read_Ambiente();

To copy to clipboard, switch view to plain text mode 

If I don't use this routine "Read_Ambiente" in the second form, there are no errors.

When I use the routine, I have this error from the linker:

diagnostica.obj:-1: error: LNK2019: unresolved external symbol "void __cdecl Read_Ambiente(void)" (?Read_Ambiente@@YAXXZ) referenced in function "private: virtual bool __thiscall Diagnostica::eventFilter(class QObject *,class QEvent *)" (?eventFilter@Diagnostica@@EAE_NPAVQObject@@PAVQEv ent@@@Z)
