Upgrading Qt

[megabenman]

I'm going to come out and say I have NO IDEA what Qt is so please excuse me if I sound like a moron :P
Anyway I'm running Kubuntu 9.04 on my iMac G5 and I'm getting graphical glitches: the icons have weird inverted colours (blue<->orange, red<->blue, etc.). I looked this problem up on the internet and found this page:
https://bugs.kde.org/show_bug.cgi?id=163028
Basically it says this bug is fixed in newer versions of Qt.
So um yeah, how do I update Qt :P I can't find any simple instructions on google.

Thanks

Re: Upgrading Qt

...I have NO IDEA what Qt is...

Qt is > Qt wiki:

Qt (pronounced as the English word "cute") is a cross-platform application development framework, widely used for the development of GUI programs (in which case it is known as a widget toolkit), and also used for developing non-GUI programs such as console tools and servers. Qt is most notably used in KDE, Google Earth, Skype, Qt Extended, Adobe Photoshop Album, VirtualBox and OPIE....

...how do I update Qt...

In the same way as other packages:

The Qt 4.5.2 has been backported by the Kubuntu developers > Topic: KDE 4.3.2 Unofficially Released for Kubuntu 9.04 (Jaunty)

The Kubuntu Backports PPA has > Package name contains: qt4-x11:

Publishing details

* Published on 2009-08-04

Changelog

* Lets try uploading with a new version number

Alternative ways > Topic: Installing QT 4.5.2 on Kubuntu 9.04


Wait few days:

Re: Upgrading Qt

How do I install packages from the PPA....
I tried downloading the tar.gz file since my computer isn't AMD or intel, extracting it, and compiling it, but I get this error:

megabenman@ubuntu:~/Documents/qt-x11-opensource-src-4.5.2$ ./configure                  
Which edition of Qt do you want to use ?                                 

Type 'c' if you want to use the Commercial Edition.
Type 'o' if you want to use the Open Source Edition.

Re: Upgrading Qt

I would:


1) Add the "code" as attach (Additional Options). The "code" is not using word wrap -> it is really hard to read .


2) Do a DIY Backport
> FAQ: Installing from source >> DIY Backport

a) Install the package: build-essential

If you have this package installed, you only need to install whatever a
package specifies as its build-time dependencies to build the package.

b) Download from the Kubuntu Backport PPA:
- qt4-x11_4.5.2.orig.tar.gz
- qt4-x11_4.5.2-0ubuntu2~jaunty1~ppa2.diff.gz
- qt4-x11_4.5.2-0ubuntu2~jaunty1~ppa2.dsc

c) Unpack with the command:

dpkg-source -x qt4-x11_4.5.2-0ubuntu2~jaunty1~ppa2.dsc

d) Read the "Build-Depends:" from the /qt4-x11-4.5.2/debian/control

e) Install those packages

f) Build the ".deb" packages with the command

dpkg-buildpackage -us -uc -rfakeroot

g) Make a local/personal repository

h) Upgrade the Qt packages from the personal repository.

Re: Upgrading Qt

Re: Upgrading Qt

Alright I have my personal repository made and setup with the sources.list file. I don't know what to do now though? I can't find anything through adept, and sudo-apt get install qt4 doesn't work (says it can't find the file). Is there something specific I need to type?

Re: Upgrading Qt

Alright I have my personal repository made and setup with the sources.list file....

How did you build your Qt packages ?

Did you build from the PPA debianized sources ?
Then there (in your personal repository) should be something like:

libqt4-assistant_4.5.2-0ubuntu2~jaunty1~ppa2...
libqt4-assistant_4.5.2-0ubuntu2~jaunty1~ppa2...
libqt4-assistant_4.5.2-0ubuntu2~jaunty1~ppa2...
libqt4-core_4.5.2-0ubuntu2~jaunty1~ppa2...
libqt4-core_4.5.2-0ubuntu2~jaunty1~ppa2...
...

and the simple:

sudo apt-get update

sudo apt-get upgrade

or

sudo apt-get dist-upgrade

should do the trick.


A checklist with the personal repository:
You have made the "Packages.gz" ?
You have updated ? (sudo apt-get update)
Do your personal repository show in the output. Here:

sudo apt-get update
...
Ign file: jaunty/debs_for_jaunty Packages

and as i have in the ~/packages/debs: autofsck_3.2-1_all.deb

So the:

apt-cache show autofsck

will tell:

Package: autofsck
Version: 3.2-1
...
Filename: debs/autofsck_3.2-1_all.deb
..
