Hi there,
I am new at QT and also new at C++
I want to have access to a batterysystem using a CAN interface. Therefore i downloaded the PCAN Basic API that consists of a .lib .dll and .h
I already included them in my .pro-file and now I want to initialize the CAN but following errors occur:
My .pro file:
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = Test
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp
HEADERS += mainwindow.h \
PCANBasic.h
FORMS += mainwindow.ui
INCLUDEPATH += C:/Qt/Projekte/Test
LIBS += -LC:/Qt/Projekte/Test-lPCANBasic
DESTDIR += Test
my .cpp
#include “mainwindow.h”
#include <QApplication>
#include <QtCore>
#include <QtGui>
#include <PCANBasic.h>
#include <qdebug.h>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
TPCANStatus result;
char strMsg256;
result=CAN_Initialize(PCAN_USBBUS1,PCAN_BAUD_500K);
if (result!= PCAN_ERROR_OK)
{
CAN_GetErrorText(result,0,strMsg);
qDebug()<<strMsg;
}
else
{
qDebug()<<“PCAN_USB Channel 1 was initialized”;
}
return a.exec();
}
here the comiling errors:

Can you help me?
