Nokia Qt installer / SDK includes the tools you need to build desktop-embedded mobile applications with Qt from a single install. This is the recommended way to get started with Qt. The SDK in this post, has a self updater feature that will keep you up to date as new versions are made available. In fact, I can sum it up by saying qt is very important to Nokia Symbian since with qt even applications designed for other Nokia smartphones like Nokia N9 which runs the Meego Harmattan OS can be ported on Nokia Symbian phones. we shall be learning about how to fix Qt unable to install error in this post
The Qt SDK version 1.2.1 released on April 11th, 2012 contains:
- Qt libraries version 4.8.1
- Simulator for Symbian phones and the Nokia N9
- Qt Creator IDE version 2.4.1
- Qt Mobility version 1.2
- Qt development tools
- Remote compilers
Qt v4.7.3 + Qt Mobility v1.1.3 + QtWebKit v4.0.8 Symbian Signed Download. This is Symbian’s Future based Application.
The new features available in this tool include – Qt 4.7.3 (for Symbian, desktop, and simulator) and Qt Mobility 1.1.3 APIs.
Qt Quick and Qt Creator 2.1 to provide a complete solution for UI development.
Tools for Symbian, Maemo, and desktop apps, including the use of native APIs.
Device binaries to enable apps created with the SDK to be run on Symbian devices. –
Qt Assistant has been added as a separate package (the result of developer requests).
Also, the installer can use system proxy on Linux.
Notification API is now marked as stable and has been moved to “Additional APIs”.
Several fixes have been made in the Qt Simulator and the installation/updating workflow
Why Do I Constantly Get QT Error Messages Anytime I Want to Install QT Apps
Having said the above the next question is that why do you get qt error messages anytime you wish to install some applications on your Nokia s60v5 and symbian^3 phones. (Note this error message is not common with Nokia Symbian Belle so if you have upgraded your Symbian os to belle then you don’t need to worry)
Another point of note is that you cannot just download any qt installer package and install it on your phone as it doesn’t work like that most of the time.
What you need to do is to download the special qt package from the link I am going to provide for at the end of this post and you are done.
Like I said earlier if you are trying to install such applications like WordPress for symbian^3, goal.com mobile application, youtube downloader, fascinate and other, and some games.
The problem also occurs on some s60v5 phones e.g Nokia N97. It doesn’t usually occur on Symbian anna because it comes pre-loaded with a newer version of the qt installer
