[quote author="Alicemirror" date="1312095237"]Later I will try with different operating systems than Mac, What platform do you used ? Mac or Win?[/quote]
Hi Enrico,
Please excuse me for the delay in my answer. I am using Qt SDK on Win XP.
Cheers,

Hi, Leon.
Does the method works now ?
As a matter of fact, if after the rules file edit you have errors this means that edit went wrong. This is a thing I am almost sure.

Yes, following the advises that I found in your discussion with matrixx I have managed to publish my app "location2sms":http://store.ovi.com/content/168861 for MeeGo Harmattan in Nokia Ovi Store. Thanks again :)

Well, I am happy for this. Now the wiki page is restored to its original content.

I've read thru all of these pages, and also the wiki, and changed my app but I cant seem to make it run!
This is the line in the rules file
$(MAKE) INSTALL_ROOT="$(CURDIR)"/debian/emirates247 installin the .desktop file this is the content
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
Terminal=false
Name=Emirates 24|7
Exec=invoker --single-instance --type=d /opt/emirates247/bin/emirates247
Icon=/usr/share/icons/hicolor/64x64/apps/emirates247.png
X-Window-Icon=
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executableNow this make the app's icon shows correctly, but when clicking on it, it only opens a black screen and it remains black.
any suggestions?
Thanks -
Hello,
sorry for the delay, I have read only in this moment the mail. Tomorrow morning I'll check you example with mine and see what It can be wrongl

@yazwas: Hi, I have done a thought on your problem. As you have pasted the piece of code without the code tag (using '@' character at the start and end of the paragraph in the wiki, I mean) it is impossible to see exactly what you have done: please do it again in a post or edit the previous.
When I experience that something goes wrong on N9 or symbian devices (inside the code at runtime I mean) I see a blank screen only as you describe. But it is a problem of the application, not the packaging instructions as I know.So we should separate the steps. Is it possible that while you have changed the files for single-insance settings you have also done something of unwanted on the rest of the code?
Please, repost the pieces you have changed as they are and not only the rules file, also the .desktop and anything else that you have changed. Then if you see already the same problem (black screen at startup) I am reasonably sure that this is a problem independent by the changes you have made for single-instnace mode. So be sure that the files thet you have changed have not missed lines, unwanted characters etc. I am aware that this is annoying operation, but this is debug... :)
If the problem occours again we should isolate two overlapping different problems. Put in your main.qml only a "hello world" instruction. It should run in single instance with your changes as your complete application will do. Then add your code seeing what is wrong. You can also add useful printout console.log() instructions in the QML docs or Qdebug() in C++ file to see where the program stops before showing the blank black screen that you notice.
If I can give you an advice, before start the changes for single-instance the best practice is to do a commit (svn or git it is the same) on a stable running application. Then do the changes and if somethings is wrong that you can't focus you should step-back and try again. This is what I have done before find a decent method reasonably sure to have the wanted results.
Let me know what's happen. Thank you.

@Alicemirror
Thanks very much for the help, I've gone thru all you said, and still did not work outWhat I did eventually was trying to build on a different machine and for some ODD reason, it works perfectly!!!!
it seems the problem was with the development station I've used originally (I dont know if that makes sense or not)
but when tryed on different machine, just compiled the same code and ran it on N9 and N950, and Yeaaaay :)Thanks for your help!

Ok! I am happy too. Because this strange "alchemy" I think MUST solve the problem but has also sense. Or at least I think I have understood the reasons for the changes that should be done.
Cheers.

I tried the workaround. I modified the .desktop file, main.cpp and the rules file. It does not break the build, but it opens only with QT creator. It does not open with the invoker command on terminal. THe booster gives an error saying "Cannot dymanically load application". Could you please me with this?
