Symbian C++ and QtCreator

TobbY

yes you can integrate your qt in carbide. And can make Qt application with carbide.c++ .And in case of Qt you have to use Qt mobiliy

tobias.hunger

I do not see any need to switch to carbide just because you use C++ code. C++ works great in Creator: Qt is C++ after all.

What is does your .pro file look like? That is what is used to create the complete build stuff, so that is most likely misconfigured.

my pro file:

@

Add files and directories to ship with the application

by adapting the examples below.

file1.source = myfile

dir1.source = mydir

DEPLOYMENTFOLDERS = # file1 dir1

symbian:TARGET.UID3 = 0xEA017DD0

Smart Installer package's UID

This UID is from the protected range

and therefore the package will fail to install if self-signed

By default qmake uses the unprotected range value if unprotected UID is defined for the application

and 0x2002CCCF value if protected UID is given to the application

#symbian:DEPLOYMENT.installer_header = 0x2002CCCF

Allow network access on Symbian

symbian:TARGET.CAPABILITY += NetworkServices

If your application uses the Qt Mobility libraries, uncomment

the following lines and add the respective components to the

MOBILITY variable.

CONFIG += mobility

MOBILITY +=

SOURCES += main.cpp mainwindow.cpp
TtsPlayer.cpp
HEADERS += mainwindow.h
TtsPlayer.h
FORMS += mainwindow.ui

Please do not modify the following two lines. Required for deployment.

include(deployment.pri)
qtcAddDeployment()
@
my pri file:
@

checksum 0x9840 version 0x40002

This file was generated by an application wizard of Qt Creator.

The code below handles deployment to Symbian and Maemo, aswell as copying

of the application data to shadow build directories on desktop.

It is recommended not to modify this file, since newer versions of Qt Creator

may offer an updated version of it.

includes I am not able to do:

@
#include <MdaAudioSamplePlayer.h>
#include <e32base.h>
#include <e32std.h>
#include <e32def.h>
@

fabio.picchi

I forgot to uncomment the line:
@
#CONFIG += mobility
@

Uncommented it and still no luck. I can include the mobility APIs now but the headers I need are not there.

I found the headers under:

@
\QtSDK\Symbian\SDKs\Symbian3Qt473\epoc32
@

but I don't know how to add this path to my project.

fabio.picchi

I managed to include the headers in the project by adding their path to the INCLUDEPATH in the .pro file. As expected, this generated a lot of build errors as QtCreator could not resolve the definitions inside the headers.

Has anyone been able to use SymbianC++ successfully? How do I include the necessary files to the project?

fabio.picchi

I apparently solved the library problems I was facing when setting as target the symbian device, and not the simulator. But now I got a new error message:

It seems that I am on the right way to build this project but I am stuck at this error right now.

Make sure you are building the target for device target and not emulator binaries.

Thanks for the reply! I am building for device target (my mistake not doing this from the start, but I am a newbie xD). That solved all the include problems I had but now I face the linkandpostlink error (described above).

Could anyone try to build the code I presented at the beginning of the topic for an N8?

Is this useful? http://www.developer.nokia.com/Community/Wiki/Building_Symbian_C++_Projects_Using_Qt_SDK

Once you can build the Symbian project then you can build the Qt wrapper.

Hi Fabio,

Were you able to achieve the output?
Did the procedure which you followed above worked? or Did you go for any other work around?

music24by7

Fixed it.....

It seems that the libraries are not picked up when i include the following to my app.pri file.

-lmediaclientaudio -lremconinterfacebase -lremconcoreapi

Now i moved this to my app.pro file and it worked.
@LIBS += -lcone -leikcore -lavkon -lmediaclientaudio -lremconinterfacebase -lremconcoreapi@

However, I don't know how to change the voice pitch/language and add different voice support.

Can anyone suggest me how to proceed.

Thanks
