WinMain problem

[Karbon_L_Forms]

trying to include a serial port communication class I got from the net (http://www.tetraedre.com/advanced/serial2.php) into my JUCE project. it had an #include <windows.h> which caused loads of grief! I got round most grief by doing

but now I’m getting

c:\SOUNDMOTION\KALI\src\Main.cpp(79) : error C2555: 'KALIApplication::moreThanOneInstanceAllowed': overriding virtual function return type differs and is not covariant from 'JUCE::JUCEApplication::moreThanOneInstanceAllowed'
        c:\SDKs\juce\src\juce_appframework\application\juce_Application.h(176) : see declaration of 'JUCE::JUCEApplication::moreThanOneInstanceAllowed'
c:\SOUNDMOTION\KALI\src\Main.cpp(84) : error C2731: 'WinMain' : function cannot be overloaded
        c:\SOUNDMOTION\KALI\src\Main.cpp(84) : see declaration of 'WinMain'

help!

Try including windows.h before juce.h in your precompiled header - that’s what I do for stuff like tracktion and it works fine…

[Karbon_L_Forms]

cheers jules.

update…

right. just had a great joy retro-fitting PCH!

cool. the winmain grief is gone but still remains the…

c:\SOUNDMOTION\KALI\src\Main.cpp(79) : error C2555: 'KALIApplication::moreThanOneInstanceAllowed': overriding virtual function return type differs and is not covariant from 'JUCE::JUCEApplication::moreThanOneInstanceAllowed'
        c:\SDKs\juce\src\juce_appframework\application\juce_Application.h(176) : see declaration of 'JUCE::JUCEApplication::moreThanOneInstanceAllowed'

I can comment out…

    bool moreThanOneInstanceAllowed()
    {
        return true;
    }

in main.cpp, but I’d still like to know whats going on.

and while I’m here, take a look at this pile o shit!

this makes no sense to me, but then I’m no expert yet. I can see NO WAY that those second definitions got in there! Image does run by the way.

[OvermindDL1]

Isn’t Kali that old, now defunct gaming service for old games? Don’t suppose you could show us the header and namespace of it? It is almost acting like it is in the juce namespace and subclassing the main app or something…

[jules]

Could the problem with the moreThanOneInstance() method be because some dodgy code is redefining ‘bool’ perhaps…?

[OvermindDL1]

bool is boolean (‘true’ or ‘false’)
BOOL is generally a WORD (‘TRUE’ or ‘FALSE’)
TRUE is 1
FALSE is 0
true is a language construct for not zero
false is a language construct effectly meaning zero

Redefining BOOL is common… to WORD though…
Redefining bool is never recommended considering it is a language construct.

If something is redefining that, then it needs to be found in that code you imported.

Hmm, also just thought, did you try having it return a BOOL and not a bool?

[sylfeline]

Karbon L. Forms -> if you succed using serial port with JUCE, can you post a little example ?

Thanks

Nah it’s just the codename for an in-house app I’m making. I’ll have a look at namespaces.

hmm. that sounds right actually. The serial port code had some well dodgy bool/BOOL defines on the go. some shite to do with Borland compilers. will defo check that out.

yep it’s working. get the (horrendously named) Tserial_event from http://www.tetraedre.com/advanced/serial2.php. I so far have wrapped it so…
(not yet robust code! first draft)

class SerialPort
{
public:
	SerialPort( AlertWindow* aw );
	virtual ~SerialPort ();
	void SerialCallback( Tserial_event *com_source, uint32 event );
	void OnDataArrival(int size, char *buffer);
private:
	Tserial_event* com;
	int            c;
    int            erreur;
    char           txt[32];
	char*			buffer;
    int				size;
	AlertWindow*	_aw;
};


/* ===============  CALLBACK    ===================== */
void SerialEventManager(uint32 object, uint32 event)
{
    Tserial_event *com;
	SerialPort* serial = 0;

    com = (Tserial_event *) object;
    if (com!=0)
    {
        serial = (SerialPort*)com->owner;
		if ( serial )
			serial->SerialCallback( com, event );
    }
}

//impl file



SerialPort::SerialPort( AlertWindow* aw )
:_aw( aw )
{
    com = new Tserial_event();
    if (com!=0)
    {
        com->setManager(SerialEventManager);
		com->owner = (void*)this;
        erreur = com->connect("COM1", 9600, SERIAL_PARITY_NONE, 8, false);
        if (!erreur)
            com->setRxSize(4);
        else
			AlertWindow::showMessageBox(  AlertWindow::WarningIcon
										, T("Serial Port Error")
										, T("Error: ") + String(erreur) );					
    }
}

void SerialPort::OnDataArrival(int size, char *buffer)
{
    if ((size>0) && (buffer!=0))
    {
        buffer[size] = 0;
		String s( buffer, 2 );
		if ( s == T("-<") ) _aw->keyPressed( KeyPress( KeyPress::spaceKey, ModifierKeys() ) );
		else if ( s == T("-.") ) _aw->keyPressed( KeyPress( KeyPress::escapeKey, ModifierKeys() ) );
		else if ( s == T("->") ) _aw->keyPressed( KeyPress( KeyPress::returnKey, ModifierKeys() ) );
    }
}

void SerialPort::SerialCallback( Tserial_event *com_source, uint32 event )
{
	switch(event)
        {	// only need one of these currently.
            case  SERIAL_CONNECTED		:   break;
            case  SERIAL_DISCONNECTED	:   break;
            case  SERIAL_DATA_SENT		:   break;
            case  SERIAL_RING			:   break;
            case  SERIAL_CD_ON			:   break;
            case  SERIAL_CD_OFF			:   break;
            case  SERIAL_DATA_ARRIVAL	:
                                        size   = com->getDataInSize();
                                        buffer = com->getDataInBuffer();
                                        OnDataArrival(size, buffer);
                                        com->dataHasBeenRead();
                                        break;
		}
}

SerialPort::~SerialPort()
{
	com->disconnect();
	deleteAndZero( com );
}

my hardware is a custom footpedal which currently is being used to control the three buttons on an alertwindow (via thier keypress codes) so it only sends data. hope this helps.

thanks all.

well I got all that multiple defs down to

mainly by removing my usage of the JUCE singleton.

SerialEventManager is a C-style function used as a callback for the Tserial_event class.

Fuck knows eh?
