Compile Error: undefined reference to QextWinEventNotifier

princelelouch94

i have followed the steps here to solve problems with "qwineventnotifier_p.h"

https://code.google.com/p/qextserialport/issues/detail?id=105

after that i got 2 another errors: undefined reference to QextWinEventNotifier

Here is my *.pro file (sources, headers, forms omitted)

@include(C:/QtSDK/qextserialport-1.2rc/src/qextserialport.pri)

QT += core gui
QT += sql

DEFINES += NCREPORT_IMPORT

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

LIBS += -L "C:/Program Files/NCReport/2.11.0.MinGW.Qt5.1.1.eval/lib" -lncreport2
INCLUDEPATH += "C:/Program Files/NCReport/2.11.0.MinGW.Qt5.1.1.eval/include"

TARGET = DBMS
TEMPLATE = app

CONFIG += qt
QT += network xml

RESOURCES +=
resources.qrc@

AND HERES MY COMPILE OUTPUT

Hi,

You have another problem first, you are mixing Qt 4.8.1 and Qt 5.1.1 which is a bad idea.
So should rather build your program with Qt 5.1.1 which includes also QSerialPort so you won't need QextSerialPort
