qextserialport help

[miilun]

I'm trying to compile qextserialport example called uartassistant. I have downloaded and unpacked qextserialport-1.2beta1.tar.gz. Then I have opened uartassistant example with Qt Creator and try to compile it, but I got this:

../../src/qextserialport_win.cpp: In member function 'bool QextSerialPortPrivate:pen_sys(QFlags<*QIODevice::OpenModeFlag>)':

What is wrong? Should I have to do something before I try to compile example? My OS is Windows 7 64bit.

The example is presumably relying on the QExtSerialPort header files being in the default include search path , and they are not. Use the INCLUDEPATH and LIBS variables in the PRO file to add the QExtSerialPort headers and libraries to the relevant paths.

go the file that you extracted, copy the folder to the folder containing your project, then in the .pro of your project add this include(../thenameofyourqextserialfolder/src/qextserialport.pri)
you will notice that the whole folder now is opened in your project.
#include "mysecondthread.h" in your class header and you will have alright with you.
consider starting example of your own it is the best starting point.
