How can I install Qserialport?
I have wrote this instruction : http://qt-project.org/wiki/QtSerialPort
but I couldn't undrestand and success to install it?
May someine writes the commans I must write in terminal to install it?
I use ubuntu 12.04 and Qt4.8
Yes, you need to type those commands in the terminal. Be sure to set QTDIR properly, too.
Or alternatively, switch to Qt5.1, QtSerialPort is part of that release, so you don't have to install it in addition to Qt.
Then how can I improve my Qt version? I am really nebie in it
Qt 5.1 is not released yet, but you can grab the precompiled beta1 packages from "this location":http://master.qt-project.org/snapshots/qt/5.1/5.1.0-beta1/backups/2013-05-10-28/.
I did that instructions and run that example but I get the Errors you can see below :
