It seems that the Qt version that QtMobility needs is greater than the version in the current SDK.

It also seems that QtMobility is not yet a mature API, but still, you can do most things without it.

Everything will be fine with PR 1.2, though.

You can, just ignore QtMobility.

QtMobility is also a little bit strange. The Simulator included in the Nokia Qt SDK crashes when I create an instance of QSystemStorageInfo.

1) I'm not 'venom', I'm Venemo.
2) It may have been uninstalled because it needs the previous version of Qt.
3) On the previous page, I wrote down how to downgrade back to Qt 4.5 again.

IMPORTANT: Don't try this unless you know why you want to upgrade the Qt packages shipped with your n900 and MAKE SURE to read ALL the previous posts on this thread for the unintended side effects. Installing these packages DOES NOT mean that all the packages that depend on Qt packages will work. In fact, I would assume otherwise.

I decided to share this because I think is a little safer than adding the SDK catalog (not easier).

There is another way to get the 4.6.2 Qt packages - you can download them from http://repository.maemo.org/pool/fre...ree/q/qt4-x11/ and install them manually.

The packages are:
libqt4-core_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-dbus_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-gui_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-maemo5_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-multimedia_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-network_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-opengl_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-phonon_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-script_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-sql-sqlite_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-sql_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-svg_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-translations_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-webkit_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-xml_4.6.2~git20100310-0maemo1+0m5_armel.deb
libqt4-xmlpatterns_4.6.2~git20100310-0maemo1+0m5_armel.deb

Because you may want to install all of them I created a small script.

A little guide:
1. Save the two attached files to a NEW folder on your n900
2. open the terminal as the root user (if you don't know how, look around but it probably means that you should not try this... )
3. go to the directory where you saved the files.
4. if you don't have wget installed, install it:

Code:

apt-get install wget

5. run the script:

Code:

sh qt4-install.txt

6. you may want to remove "mp-fremantle-generic-pr" to avoid broken dependencies (again read first post on this thread)

The script(qt4-install.txt) is very simple and reads the list of files to download and install from the second file(qt4-packages.txt):

Code:

#!/bin/sh
while read line; do
	echo 'downloading: '$line
       	wget http://repository.maemo.org/pool/fremantle/free/q/qt4-x11/$line 
	dpkg -i $line
done < qt4-packages.txt

Last but not least: I BELIEVE developers should have (and had) their applications linked with the qt4-maemo (experimental) packages until PR 1.2 is out. It is just easier for users to install them and does not require hacks. The current policy to block qt packages from moving to testing sends a different message. A message that the right way of doing is using the "stock" packages that don't exist on the device. If you do so then you can't run the application on the device until PR 1.2 is out or you have to try some hack like this.

same problem here with mymenu, it needs previous qt version! solution: downgrade, or wait for pr 1.2 in order to arrange menu as u like!

ps. u can try "catorize", similar app which works with this qt version(or maybe doesn't need qt at all) :O

Thanks for your guide!

And thanks for pointing this out.
It is exactly what I recommended in my first post.

In fact, I prefer this:
- For development, use Qt 4.6, as the guides say. It is far more convenient, because Nokia Qt SDK needs it.
- For deployment, link to the experimental packages so regular users can install the apps.

Saxen,
I thought you may want to know that I was able to download the Qt Mobility 1.0 source code, compile using scratchbox and install on my phone.

Even better I was able to compile it against the qt4-maemo5-* packages so it does not even require this hack to work.

p.s. The only module that failed was the messaging but I attempt to find out why because I don't have a need for it yet
