Libtins in Qt

  • 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:

    #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() << ':' << << " -> "
                  << ip.dst_addr() << ':' << tcp.dport() << std::endl;
        return true;
    int main(int argc, char *argv[])
        QCoreApplication a(argc, argv);
        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'
    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.

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