NokiaQtSDK Simultor build problem on Ubuntu 10.04

Hi all,

I am trying to build a sample app on Ubuntu using NokiaQtSDK 1.0 for Qt Simulator as build configuration. Unfortunately I am getting build error, where as Desktop build is successful. I tried to add <mypath>/NokiaQtSDK/Simulator/Qt/gcc/lib to Library path, but still unsuccessful with build. Here I am posting my console output. May be it is silly issue, but I am quite new to Linux platform and serious about developing on Ubuntu with Nokia Qt SDK only. Any help is much appreciated

Error while building project testapp1 (target: Qt Simulator)
When executing build step 'Make'

Libraries shipped with Qt Simulator for some reason are not compatible with your platform. Were installation of Nokia Qt SDK complete?
Just in case try [I]make distclean[/I] and rebuild the project.

No notable errors during installation except a .sh script error for Maemo (I hope it doest have anything to do with QtLibs). NokiaQtSDK dint work out of box on first run. It reported linking errors that it cant find libQtGui etc. I hope they should be installed with NokiaQtSDK. Then I have to do a manual installation of Qt4libs as

sudo apt-get install libqt4-dev
then relevent libs are installed in /usr/bin

After manual installation Desktop build is sucessful, but not Qt Simulator build. What is understand is libs installed by NokiaQtSDK are not picked up for some reason. Correct me if I am wrong, and any help is much appreciated

By the way I installed NokiaQtSDK 32bit version on 32bit machine.

This has no effect on Qt Simulator as it uses it's own copy of Qt libraries. I suggest you to remove and install SDK again.

Uninstalled SDK using the supplied maintainance tool and reinstalled it, but problem exists.
I suspect the same as you pointed that NokiaQtSDK uses its own libs. But as i pasted in the first thread, it is picking the correct qmake of NokiaQtSDk, but not the libraries. Any sugesstions are helpfull.

In the installed folder of NokiaQtSDK i could find only the folder with the name Simulator, but not any folder that has pure Qt libs. So the basic questions - If I install only NokiaQtSDK (no Qt SDK exists in my ubuntu 10.04 system) can I develop for linux desktop and other nokia platforms (Maemo, Symbian - i understand remote compiler stuff)?
OR
Should I install a dektop Qt version and then install NokiaQtSDK?

Any help is really appreciated. Thanks in advance.

Hi if you are going to start using Remote Compiler read [URL="http://wiki.forum.nokia.com/index.php/How_to_install_and_use_the_Nokia_Qt_SDK_Remote_Compiler"]How to install and use the Nokia Qt SDK Remote Compiler[/URL] and in particular the section [URL="http://wiki.forum.nokia.com/index.php/How_to_install_and_use_the_Nokia_Qt_SDK_Remote_Compiler#Ubuntu_10.04_Simulator_Compiler_installation"]Ubuntu 10.04 Simulator Compiler installation[/URL]

Many of the problems you encountered are solved in this article
Thanks

This will cause lots of problems doing this there is lots of incompatibility with early versions of Qt4

I believe this might be version Qt 4.5 !!!.
do the following command
sudo apt-get remove libqt4-dev

Then download Qt X11 Desktop from [URL="http://qt.nokia.com/downloads/sdk-linux-x11-32bit-cpp"]Qt SDK for Open Source C++ development on Linux/X11 32-bit [/URL]

chmod u+x qt-sdk-linux-x86-opensource-2010.04.bin
you should now be able to execute the file as normal. You can do this from the command line by typing:

./qt-sdk-linux-x86-opensource-2010.04.bin
This could be installed under a separate username if you want to keep them apart as this installs another version of Qt Creator and this will be confusing for you.
Thanks,
Jim
