Libtins in Qt

Nisha

Hi,
When i include libtins library in qt version 4.8 project file as follows:

QT       += core

QT       -= gui

TARGET = test
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app

INCLUDEPATH +=include
LIBS += tins.lib

SOURCES += main.cpp

i have already included the include and lib file in the folder test..
main file of this test project looks like this:
main.cpp

#include <QtCore/QCoreApplication>
#include <iostream>
#include <tins/tins.h>

using namespace Tins;


bool callback(const PDU &pdu) {
    const IP &ip = pdu.rfind_pdu<IP>(); // Find the IP layer
    const TCP &tcp = pdu.rfind_pdu<TCP>(); // Find the TCP layer
    std::cout << ip.src_addr() << ':' << tcp.sport() << " -> "
              << ip.dst_addr() << ':' << tcp.dport() << std::endl;
    return true;
}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    Sniffer("eth0").sniff_loop(callback);
    
    return a.exec();
}

and i am getting undefined reference errors as follows

In function Z8callbackRKN4Tins3PDUE': test\main.cpp:12: error: undefined reference to _imp___ZN4TinslsERSoRKNS_11IPv4AddressE'
test\main.cpp:20: error: undefined reference to _imp___ZN4Tins7SnifferC1ERKSsNS0_12promisc_typeES2_b' test\include\tins\ip.h:389: error: undefined reference to _imp___ZN4Tins11IPv4AddressC1Ej'
etc.........
can anyone propose a solution for that......

Thank u

@Nisha Did you try to put whole path to the lib like:

LIBS += c:/mylibs/tins.lib

Is that lib built using the same compiler? On Windows the lib must be built using EXACT the same compiler.

@Nisha
also make sure that you rerun qmake once you make changes to your .pro file.
