qDebug macro substitution

[the_bis]

I want to create a macro that expands to qDebug, so I suppress the qDebug output in release build.
How can I do it correctly?

I tried with:

#ifdef MY_DEBUG
#define QDEBUG(x) qDebug(x)
#else
#define QDEBUG(x)
#endif

#ifdef MY_DEBUG
#define QDEBUG(x) qDebug(x)
#else
#define QDEBUG(x)
#endif

To copy to clipboard, switch view to plain text mode 

but I have a problem with multiple qDebug parameters like:

qDebug ( "ENTER in DeviceConfiguration = %s\n", moduleName.ascii() );

qDebug ( "ENTER in DeviceConfiguration = %s\n", moduleName.ascii() );

To copy to clipboard, switch view to plain text mode 

Any help?
Thanks,

This works for me (using TRACE instead of QDEBUG, of course):

#ifdef DEBUG
        #define TRACE qDebug
#else
        #define TRACE(fmt,arg...) ((void)0)
#endif

#ifdef DEBUG
        #define TRACE qDebug
#else
        #define TRACE(fmt,arg...) ((void)0)
#endif

Yes! It works!

My project.pro is now:

[...]
CONFIG  += qt warn_on debug
[...]
debug {
  DEFINES += MY_DEBUG
}
[...]

[...]
CONFIG  += qt warn_on debug
[...]
debug {
  DEFINES += MY_DEBUG
}
[...]

and my project.cpp is now:

#ifdef MY_DEBUG
#define QDEBUG qDebug
#else
#define QDEBUG(fmt,arg...) ((void)0)
#endif
[...]
QDEBUG ( "Value now is %s\n", varResult.ascii() );
[...]

#ifdef MY_DEBUG
#define QDEBUG qDebug
#else
#define QDEBUG(fmt,arg...) ((void)0)
#endif
[...]
QDEBUG ( "Value now is %s\n", varResult.ascii() );
[...]
