Vtable Error in Symbian API under Qt

MamdouhAlShamy

hi,

im trying to use TTS under Qt creator as described in "this":http://wiki.forum.nokia.com/index.php/Symbian_S60_API_In_Qt_Project

im using "CTtsPlayer":http://cally.iat.sfu.ca/research/attachment/1174162216.zip

and calling the TTS by

@ #if defined(S60_32)
#elif defined(S60_50)
#else
//for Symbian^3
#include <aknnotewrappers.h>
#include "stringloader.h"

   CTtsPlayer player = CTtsPlayer::NewLC();
  TBuf<255> aBuffer( _L("MMS") );
    player->PlayTextL( aBuffer );
#endif@

and . pro has

 @   LIBS += -leuser -lapparc -lcone -leikcore -lavkon -lefsrv -lestor@

but im getting errors

@ multiple definition of 'vtable for CTtsPlayer'
multiple definition of 'non-virtual thunk to CTtsPlayer::MapcPlayComplete(int)'
@
any solution

any solution

MamdouhAlShamy

about "CTtsPlayer::MapcPlayComplete"
it is found in CTtsPlayer and declared virtual

@
void CTtsPlayer::MapcPlayComplete( TInt aError )
{
iErr = aError;
iPlaybackInProgress = EFalse;
// Let the paused PlayTextL complete
iWaiter->AsyncStop();
}
@

and the class inherits from MMdaAudioPlayerCallback

Perhaps it would help to ask the developers of CTtsPlayer?

i tried this Class on Symbian Project under Carbide C++
, and it worked fine

but in mixing Qt with Symbian APIs it fails

MamdouhAlShamy

any idea what is " vtable "

"well...":http://lmgtfy.com/?q=vtable

MamdouhAlShamy

solved by cleaning includes of header files
as as each file as refering to each other in a bad way

vtable issues are sometimes caused by moc not working on all files it should work on. Rerunning qmake does help most of the times for me.

A clean rebuild usually fixes the rest of the cases:-)

thx all

the solution that some header files missing and other are duplicated in a bad way
