Open C/C++ plugin installation problem

iyedb — Sun, 22 Nov 2009 23:57:27 GMT

Hello everybody,
I am trying to install open C plugin v1.6 on S60 5th edition SDK. The SDK is correctly installed Carbide is configured with the SDK as well everything works fine. But when I run the open C plugin installer well, it installs nothing. The installer shows the following information:
space required on D: 0 K
space required on D: 5000024 K
At the end nothing is installed.
According to the release note of open C everything should be installed in EPOCROOT\nokia_plugin folder but there is no such folder in my SDK tree in the first place.
Am I missing something ?

I would appreciate any help.
cheers
a fellow developer.

e71: How to force sip register?

seandarcy2 — Sun, 22 Nov 2009 22:38:18 GMT

I'm trying to set up a group of e71's with asterisk. I'm having a problem with setting up the sip profiles. I can see the attempted registration is asterisk. But if I make a change in asterisk, I can't find a way to make the e71 try to register again.

I assume it's there somewhere, but where?

Capturing key press or long key press while key lock is on in S60 5th edition

pedramz — Sun, 22 Nov 2009 22:16:55 GMT

I have been trying to capture long key presses in S60 5th edition while key lock is on with no success. I am using CaptureKey and CaptureLongKey which works fine when the key lock is off and even when the key lock is on in most S60 3rd edition phones.

I have seen application running on S60 5th edition phones which seem do to what I'm trying to do for example Dr Jukkas's Key Lock Clock application.

My question is whether this is done in a completely different way in for instance Key Lock Clock. Should I be looking for something other than CaptureKey and CaptureLongKey?

Thanks in advance for any suggestions.

[moved] SVG problems

rmanor — Sun, 22 Nov 2009 22:10:20 GMT

Hi,

I'm using Carbide and I want to put SVG images in my image controls (CEikImage).

I loaded my SVG into the MIF file and in the designer I see everything correctly.
The generated code looks fine (using IconUtils).

When I run the program, I don't see the icons at all in the emulator.
Just blank.

The SVG files were saved using Inkscape.
I tried converting them to SVG-T using the converter but it totally messed up the images.

What am I doing wrong?

Thanks.

Java FX support...

ErikEngerd — Sun, 22 Nov 2009 21:55:58 GMT

Hi,

When I am deploying a simple JavaFX application packaged using javafxpackager as a mobile application (jad,jar), I get the messages on the N97 saying that the application is incompatible with the phone.

Am I doing something wrong? Is java fx supported already? If not, when will it be?

Cheers

max alarm recurrence count?

gybrush — Sun, 22 Nov 2009 21:18:20 GMT

Hi all,

have anybody noticed that there is a max count how many times an alarm can be snoozed? I think it is 10 times. After that the "snooze" button no longer appears.

Is anyone aware of a way to turn off this feature (programmatically or from the UI)?

Pulsar Beginner

Robotuner — Sun, 22 Nov 2009 20:22:43 GMT

Hi:
I am trying to set up and learn how to develop on Eclipse Pulsar for S60. I have managed to create my package and install the template midlet application Hello World and Display Manager Templates.

My problem is that for both those templates, when I try to run as Emulated Java ME Midlet, I get the error message "Symbian SDK Error", Failed to initialize session. Caught exception: java.net.ConnectException: Connection refused: connect

Can someone give me a clue as to what is causing this and how to fix? My installation is on a clean Win XP virtual machine with Pulsar for Mobile Java Developers Build 20090920-1017

Thanks

running application in C on mobile phone with Symbian

johnyjj2 — Sun, 22 Nov 2009 19:03:46 GMT

Hello :-)!

SUMMARY: How to run pocketsphinx_continuous on mobile phone with Symbian, and how to do it with simulator of mobile phone with Symbian. PocketSphinx can be downloaded for free here, for both Linux and Windows: http://cmusphinx.sourceforge.net/html/download.php .

------------------------------------------------------------------------------------------------------------

SHORT EXPLANATION

I'd like to create application for mobile phone and server such that:
1. User runs application on mobile phone with Symbian, this application uses PocketSphinx. It is Automatic Speech Recognition software for devices like mobile phones, written in C. Somebody told me that "Pocketsphinx is used successfully on Symbian with minimal effort". My knowledge about Symbian is limited but I know something about CMU Sphinx. Can you help me, please, to run this PocketSphinx on Symbian? I also need to find simulator of mobile phone with Symbian. I have already found Wireless Toolkit and I tried to use this emulator, however I think it doesn't allow to run simulation of mobile phones with Symbian. (By the way I am limited in my project to mobile phone of the price up to about 160 euro; which Symbian version would be best for my application?).
2. This application communicates with the user. The users speaks digits and some other words (dictionary is about fifteen words, I can create language and acoustic models, as well as formal grammar in CMU Sphinx, with the use of SphinxTrain). The application recognizes those digits.
3. Based on this talk, mobile phone sends information about results of recognition to the server. I can do it in Java for CLDC/MIDP with httpconnection, POST method on the mobile phone side and with Tomcat on server. I think this httpconnection must be possible not only in Java ME, but also in Symbian C. But this is thing which will bother me later, now I'd like to run pocketsphinx_continuous on Symbian and try to modify it according to my needs.

Summing up, what I'd like to know is how to run demo pocketsphinx_continuous on mobile phone with Symbian, and how to do it with simulator of mobile phone with Symbian. (I've got Wireless Toolkit but I think it is not capable of running Symbian). PocketSphinx can be downloaded for free here, for both Linux and Windows: http://cmusphinx.sourceforge.net/html/download.php . There are two ways of installing it in Ubuntu. First is to unpack it (it is tar.gz), enter its directory and type "./configure", "make", "sudo make install". The other, different, is written in README file, i.e. run autogen.sh, "./configure", "make clean all", "make test", "make install". The result should be, among many other files, javadoc in doc directory.

------------------------------------------------------------------------------------------------------------

LONG EXPLANATION

What is required to give me some advices is written above. So if you don't want / don't have time to read the whole text, just above explanation is enough. But let me say about other possible approaches which I try to do. Those are worse than what I explained above, but I also tried them.

CMU Sphinx contains SphinxTrain to create acoustic model. It has got some different recognizers (also called decoders), those are PocketSphinx, Sphinx4 and some other. PocketSphinx is written in C and is for devices like mobile phones. Sphinx4 is Java application for PCs because it requires better hardware. There is good tutorial about using SphinxTrain with Sphinx4. It is here: http://www.speech.cs.cmu.edu/sphinx/tutorial.html . There is no similar tutorial for PocketSphinx. However with some knowledge about Symbian and C it is possible to run it on Symbian. The other approach than PocketSphinx, is using this Sphinx4. However it requires connection between mobile phone and server, sending audio data from cellular phone to server. It can be done with Skype, but there is still problem on server side with redirecting sound from Skype to Sphinx4. So you see there are two different approaches. One is to run speech recognition on mobile phone with PocketSphinx and Symbian. The other is speech recognition on server with Sphinx4. There are some ways to follow this second option. One is Skype on both server and mobile phone. (But there is problem with redirecting speech from Skype to Sphinx4). The other is too expensive Digium card. The third one is IVR, but I still look for good open-source IVR software. All of those three ways of second option involve Sphinx4. It was much easier to create application with Sphinx4. It is for PCs, not embedded devices, because it requires better device, extensive floating point math and some other things. But it has much better documentation than PocketSphinx. But I want to use PocketSphinx because I don't need to pay to anybody for access to mobile internet in order to send data through internet for application like Skype. The access to internet is required only for short time to send little text data with httpconnection, POST method. This is why I'd like you to help me, please, with running pocketsphinx_continuous on simulator of PocketSphinx on mobile phone with Symbian. (By the way, I see I've got installed S60 Developer Tools -> 3rd Edition FP1 SDK -> MIDP -> Emulator).

Summing up in a list, those are in CMU Sphinx:
I. SphinxTrain, which I can use to create files needed for speech recognition
II. decoders which use speech input and some files which I create with SphinxTrain, to follow speech recognition (input speech + files from SphinxTrain = are used by decoder)
II-1. PocketSphinx, written in C, for devices like mobile phones
II-2. Sphinx3, written in C, for PCs, actually the best developed
II-3. Sphinx4, written in Java, for PCs, with the best documentation
II-4. Some other, older versions

Those are possible approaches of solving my task:
I. Speech recognition on mobile phone with PocketSphinx. This is much better way than [II].
Problems: 1. running PocketSphinx on mobile phone with Symbian. 2. simulating mobile phone with Symbian on PC. I also thought that maybe I should consider Meamo, what do you think about it? Or use things different than CMU Sphinx, e.g. Simon, HTK, Julius. I looked at those other ASR engines and I think PocketSphinx may be best choice.
II. Speech recognition on server with Sphinx4. There are some different ways of establishing voice connection between mobile phone and server.
II-1. ordinary call from mobile phone to server; server has got Digium card. Disadvantage: Digium card is expensive.
II-2. to use Skype on both mobile phone and server. Problem: redirecting of sound from Skype to Sphinx4 and vice versa.
II-3. can you think about any other ways? I found that Asterisk may be useful.

updating screen after custom screen change

rubizm — Sun, 22 Nov 2009 18:48:31 GMT

Hi,

I made to do a complete change to the app skin, text colors and all... (this is not skin aware app.. it's custom skin) I am very happy :)

ONLY that the ui is not updated totaly (text/icon colors do not refresh) unless the screen is changed from portrait to landscape (or vs versa)

So, is there a way to tell the screen that resources had changed??

It seems I have tried all methods..

=========================
tried to tell the screen it's resolution changed (did nothing)
SendUserEvent( EEventScreenDeviceChanged );
=======================
clearing the screen, did not even do the work for the main screen area (not to talk about the status pane)

CWindowGc& gc = SystemGc();
gc.Clear()...

==========================
this is a strange "Clear Screen API" (a whole API for clearing the screen??) did a flicker but did not help.

CAknLocalScreenClearer

======================
calling DrawNow() of any CCoeControl/appui in the area did nothing as well

========================
The only thing that worked was

SetOrientationL( CAknAppUiBase::EAppUiOrientationLandscape );
SetOrientationL( CAknAppUiBase::EAppUiOrientationPortrait );

causing a long flicker...

So my question is, can I capture the screen device or something so that the flicker is hidden?

or is there another way of telling the screen there are new skins/colors to use?

Thanks

Going Beyond Hello: A Tutorial for Symbian C++ Applications

jingjingGER — Sun, 22 Nov 2009 18:08:49 GMT

Hi developers,

I currently try to let the 'Going Beyond Hello....' example
working properly on my Windows Vista Ultimate.

After having some trouble with the first introducing tutorial
(Symbian C++ Quick Start) in combination with Windows Vista,
everything is working fine now.

The HelloWorld project works on both, the emulator and the
device.

In the second tutorial everything is working referring to the
emulator. But after switching the active-build configuration to
'Phone Release (GCCE)[S60_5th_Edition_SDK_v1.0]' through the
'Manage configurations for current project toolbar' icon, I
get the following error message:
Bareword "BACKUP" not allowed while "strict subs" in use at \S60\devices\S60_5th_Edition_SDK_v1.0\EPOC32\BUILD\Users\forensix\Downloads\HelloSymbianWorld_Example_Code\HelloWorld\group\/Platform.pm line 43.
Compilation failed in require at C:\S60\devices\S60_5th_Edition_SDK_v1.0\epoc32\tools/ABLD.PL line 175.
BEGIN failed--compilation aborted at C:\S60\devices\S60_5th_Edition_SDK_v1.0\epoc32\tools/ABLD.PL line 175.

I thought ok, try to comment out 'use strict'
in Platform.pm.

After that I get this error messages:

1:
make[1]: \S60\devices\S60_5th_Edition_SDK_v1.0\EPOC32\BUILD\Users\forensix\Downloads\HelloSymbianWorld_Example_Code\HelloWorld\group\HELLOWORLD\GCCE\HELLOWORLD.GCCE: No such file or directory

2:
make[1]: *** No rule to make target `\S60\devices\S60_5th_Edition_SDK_v1.0\EPOC32\BUILD\Users\forensix\Downloads\HelloSymbianWorld_Example_Code\HelloWorld\group\HELLOWORLD\GCCE\HELLOWORLD.GCCE'. Stop.

So I hope someone can help me to exclude this buggy behaviour.

Thanks

using messaging API

ijazhasan — Sun, 22 Nov 2009 17:41:09 GMT

Can I use the messaging API in an application and self sign the application? That is I can import the application to my phone and it would work?? Similarly can I access the phone book and self sign the application???
