Qt on TK1 -- QSerialPort result in error

Phong

I got a TK1 with L4T 14.04 ubuntu, and install qt5 by using

sudo apt-get install build-essential qt5-default qtcreator -y

Since I wanna read serial port data from Arduino Tx output, I have to install libqt5SerialPort !

So~ I install it by using

sudo apt-get install libqt5serialport5-dev

Everything seemed to be good, until I start coding.

I just open a new project with mainWindow (also tried dialog later) ,
and add
Qt += serialport Compile --> passed

#include <QSerialPort> Compile --> ERROR!!!!

and even I delete the include, it still failed!!

here is my Error Msg :

/usr/bin/ld: cannot find -ludev
collect2: error: ld returned 1 exit status
make: *** [Test1] Error 1
15:34:47: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project Test1 (kit: Desktop)
When executing step 'Make'
15:34:47: Elapsed time: 00:05.

Can anyone help ?? TK1 is so.....unfriendly, BTW.

Hi,

From the error message, you need to install the udev dev package

@SGaist Oh~!! Thanks~! I fixed the problem now, thanks a lot!!

BTW, Do u know how can I use Qt to receive the data passed by Arduino Tx pin ??

I can detect the arduino by USB Port (ttyACM0) use QSerialPort, but I don't know how to detect Pins on TK1 / Rasp Pi by Qt.
Also use QSerialPort lib. ?

Do you mean receive the data sent by the Arduino ?

If so, use the readyReady signal to get notified when something arrived.

Hi..i am a new user here. By profession i am a hardware design engineer. As suggested i think you should use that udev dev package. Also you can do another thing and that is try to update your libraries.

@NeilKeiding
yup, I download the package and the problem fixed.
thanks a lot.

@SGaist
Yes, I wnat to receive from Arduino, and I finally used the FTDI converter to transfer RS232 to USB.
and yes, ReadyRead is useful.
Thanks for helping.
