Error Including Symbian C++ APIs

[amir]

Hi there,

Recently, I'm developing a Symbian App using Qt.
There is big problem driving me crazy :

I'm Using Qt 4.7 and I wanna Use Text-to-Speech API of S60.
Here is the code :

ttsplayer.h :


#ifndef __TTSPLAYER_H__
#define __TTSPLAYER_H__

// Include Files
#include <MdaAudioSamplePlayer.h>
#include <e32base.h>

class CTtsPlayer : public CBase, public MMdaAudioPlayerCallback
{
public:
// construction
static CTtsPlayer* NewLC();
~CTtsPlayer();
/** Simplified call'n'forget interface.
* Synchronous function
* @leave System-wide error codes. @see MMdaAudioPlayerCallback errors
*/
void PlayTextL( TDesC& aText );
// From the observer interface
public:
virtual void MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds &aDuration);
virtual void MapcPlayComplete(TInt aError);
private:
void ConstructL();
private:
CMdaAudioPlayerUtility* iPlayer;
TBool iPlaybackInProgress;
CActiveSchedulerWait* iWaiter;
// Playback error code
TInt iErr;
};


#endif // __TTSPLAYER_H__

// End of file


ttsplayer.cpp :


// Include Files

#include <e32base.h>
#include <e32std.h>
#include <e32def.h>
#include "TtsPlayer.h"

// Prefix telling the audio utility that TTS should be used
_LIT( KTtsPrefix, "(tts)" );

CTtsPlayer* CTtsPlayer::NewLC()
{
CTtsPlayer* self = new (ELeave) CTtsPlayer;
CleanupStack::PushL( self );
self->ConstructL();
return self;
}

CTtsPlayer::~CTtsPlayer()
{
delete iWaiter;
delete iPlayer;
}

void CTtsPlayer::ConstructL()
{
iPlayer = CMdaAudioPlayerUtility::NewL( *this );
iWaiter = new (ELeave) CActiveSchedulerWait;
}

void CTtsPlayer::PlayTextL( TDesC& aText )
{
__ASSERT_ALWAYS( iPlaybackInProgress == EFalse, User::Leave( KErrNotReady ) );
HBufC8* playableText = HBufC8::NewLC( aText.Length() + KTtsPrefix().Length() );
playableText->Des().Append( KTtsPrefix );
playableText->Des().Append( aText );
iPlayer->OpenDesL( *playableText );
iPlaybackInProgress = ETrue;
iWaiter->Start();
// At this point playback is already completed or failed
User::LeaveIfError( iErr );
CleanupStack::PopAndDestroy( playableText );
}

void CTtsPlayer::MapcInitComplete( TInt aError, const TTimeIntervalMicroSeconds& /*aDuration*/ )
{
iErr = aError;
if( aError != KErrNone )
{
iPlaybackInProgress = EFalse;
// Let the paused PlayTextL complete
iWaiter->AsyncStop();
}
else
{
iPlayer->Play();
}
}

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


and in the mainwindow.cpp I use this like this :


CTtsPlayer* player = CTtsPlayer::NewLC();
_LIT( KTextToSay, "All your voices are belong to us!" );
TBuf<100> bTextToSay( KTextToSay );

TRAPD( err, player->PlayTextL( bTextToSay ) );
if( err != KErrNone )
{
qDebug() << QString("TTS playback failed with [%1]").arg(err);
}
else
{
qDebug() << "TTS playback completed successfully" ;
}
CleanupStack::PopAndDestroy( player );


and I also added these files(ttsplayer.cpp,ttsplayer.h) to symbian in .pro file.
But Now my problem is errors below :
:-1: error: Recipe compile failed with exit code 1.
:-1: error: The make-engine exited with errors.

Please Help.
Thanks in advance.

I really have no idea. But if those are errors reported in the "Build issues" tab, you may have some detailed and important information in the "Compile Output" tab, which might actually tell you what the problem is and where it is.

Here is the compile output :

Thanks a lot for answering me.

[amir]

Can anyone tell me what should I do?

Thanks.

You need to link against the library which provides the missing symbols - add the following to your .pro file:


LIBS += -lmediaclientaudio
The CMdaAudioPlayerUtility page in the developer library (http://library.developer.nokia.com/index.jsp?topic=/S60_5th_Edition_Cpp_Developers_Library/GUID-35228542-8C95-4849-A73F-2B4F082F0C44/sdk/doc_source/reference/reference-cpp/Multimedia_Framework/CMdaAudioPlayerUtilityClass.html) tells you which library to link against.

Hi,

I am developing an TTS app on Qt-SDK 1.1.3, I am using the TTS utility developed by Artem Marchenko for this.
The sources are same as which Amir has pasted here.

Now, I am facing a linking problem. I followed the suggestions above but still it didn't help.

I have added the mediaclientaudio library in the .pri file, but still getting the linking errors:


/QtSDK/Symbian/SDKs/Symbian1Qt473/EPOC32/BUILD/QtProjects/myappilcationname_EXE/GCCE/UREL/TtsPlayer.o: In function `CTtsPlayer::ConstructL()':
ttsplayer.cpp:(.text+0xf6): undefined reference to `CMdaAudioPlayerUtility::NewL(MMdaAudioPlayerCallb ack&, int, TMdaPriorityPreference)'

ttsplayer.cpp:(.text+0x160): undefined reference to `CMdaAudioPlayerUtility::OpenDesL(TDesC8 const&)'
make[2]: *** [\QtSDK\Symbian\SDKs\Symbian1Qt473\epoc32\release\g cce\urel\myappilcationname.exe] Error 1
make[1]: *** [TARGETFLASHCARDS_EXE] Error 2


In my application.pri file, i have added
LIBS += -lcone -leikcore -lavkon -lmediaclientaudio

Can anyone suggest me how to resolve this issue? I am stuck at this point.

Thanks,
Sudhir

Another update, If I select the build variant as Symbian3, then i am getting an strange error as below:


Recipe compile failed with exit code 1.
The make-engine exited with errors.

This is the same which Amir got...

Can anyone help me to get out this issue please?

Added after 51 minutes:

Hi,

I opened the MdaAudioSamplePlayer.h from the Qt-Creator to found that there are some errors in that file.

I am attaching the screenshot here, you can see that there is an
Unexpected token * popup note when i focus on the error lines.

Please help,

Thanks
