qt serial port

[saman_artorious]

I am using Qt 5. I need the serial class, I tried adding += serialport, but it fails. anyone knows which serial class is most suitable for serial communications (better be an interface class) as well as instructions to set it up in
Linux ?

What happens?

Give more info.

If you use QtSerialPort, then after building need to install library (maybe required superuser privileges for installation). See more info on WIKI!

What happens?

it gives the following error:

:-1: error: [Makefile] Error 3 File no found

And what? You really scoff at us?

At such approach you won't receive any answers from us (from me).

I replied to Santosh question, as I was not sure if this module already exists in qt5 or shall installed as a seperate library. And... next time please make sure you are implying to the correct matter when you accuse members.

anyway,

My problem is with /usr/bin/moc-qt4, I already added /usr/bin/qt4 to the environment variable. but I cannot find anything called moc-qt4 in the system. I have qt 5 installed, but at we need qt4-qmake for libqtserial, I downloaded the package.

lib-qt4-dev was missed!
I cannot make, it cannot identify qtSerialPortInfo library.

why this happens? the QserialPortInfo.so file is already inside the src directory. I can also include it in qt application. but make fails!
