Symbian C++ and QtCreator
-
Hello,
I am trying to develop an application that involves TextToSpeech (TTS) for Nokia N8. As Qt does not have a TTS API built-in, I had to search for one over the Internet. Turns out that I found a very good API, but it did not offer support for Symbian at all (QtSpeech - http://lynxline.com/projects/qtspeech/).
In my quest to find an API for TextToSpeech I found one developed by Artem Marchenko. It seems to be just what I need for my application but I cannot find a way to include the necessary headers, they doesn't seem to be found by QtCreator. I searched for the headers inside QtSDK directories and found them, but the IDE keeps telling me they are not there.
I would like to know if anyone has a similar problem or if it's a compatibility issue. I have been stuck with this problem for 2 days now and can't find a solution.
I will paste the code here for reference:
"TtsPlayer.h"

As for pure Symbian C++ programming, you'd better use IDE Carbide rather than creator: http://www.developer.nokia.com/Resources/Tools_and_downloads/Other/Carbide.c++/
-
Is it possible to use QML and other Qt features in this IDE?
-
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.uiPlease 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:

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.
-
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?
-
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:

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? -
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
