Serial Port programming not working with any library

I have downloaded the latest version of QT4 and the SDK and I am using it on Ubuntu 10.04.
That is working perfectly OK.

On studying all the forums and help online I could find out 3 projects that are used for accessing the serial port in QT.
qextserialport, qserialdevice and a very lesser known qport.

QEXTSERIALPORT:
I have downloaded the qextserialport-1.1.tar.gz file and unzipped in a folder.
THen i open the .pro file in directory and give Build All in the QT Creator.
I get the following... and no DLL's are created.

Starting /home/kpkale/Programs/Downloaded Examples/qextserialport/examples/event/event...
/home/kpkale/Programs/Downloaded Examples/qextserialport/examples/event/event: error while loading shared libraries: libqextserialport.so.1: cannot open shared object file: No such file or directory
/home/kpkale/Programs/Downloaded Examples/qextserialport/examples/event/event exited with code 127


I am stuck up here as I did not get a valid solution to get this thing working...
//************************************************** ****
I also used another method as shown in this link
http://code.google.com/p/aileron/sou...ers.wiki?r=324

Here, first is could not understand how to differntly do "Manually build the qextserialport project." and moreover, I could not proceed to downloading the telem project... dont have experience on downloading using svn...


QSERIALDEVICE:
I have downloaded the tar file from this link.
http://qt-apps.org/content/show.php?content=112039

I unzipped it in a folder and then opened the BuildLIbaray.pro in QTCreator. WHen I give Build ALL It gives me a lot of errors and below.

How can I proceed with any one of them...

I need to get one small application completed for I/O on serial port.

Install libudev-dev package to get libudev.h.

The version that you downloaded QSerialDevice - obsolete!
Use version 2.0: http://gitorious.org/qserialdevice/q...ve-tarball/2.0

Thanks oleg and kuzulis

I will try both these things and post the results...
