Solved Including libtins in Qt
-
I included the libtins library in qt by project->add library option
my code looks as follows
samplelibtins.pro...........#------------------------------------------------- # # Project created by QtCreator 2016-11-02T13:03:33 # #------------------------------------------------- QT += core gui greaterThan(QT_MAJOR_VERSION, 4): QT += widgets TARGET = samplelibtins TEMPLATE = app SOURCES += main.cpp\ mainwindow.cpp HEADERS += mainwindow.h FORMS += mainwindow.ui LIBS += -ltins\ -lWs2_32.lib\ -lIphlpapi.lib -lwpcap\ -lPacket\ win32:CONFIG(release, debug|release): LIBS += -L$$PWD/lib/ -ltins else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/lib/ -ltinsd INCLUDEPATH += $$PWD/include DEPENDPATH += $$PWD/include win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/lib/libtins.a else:win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/lib/libtinsd.a else:win32:!win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/lib/tins.lib else:win32:!win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/lib/tinsd.lib
main.cpp..........
#include "mainwindow.h" #include <QApplication> int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w; w.show(); return a.exec(); }
mainwindow.h.................
#ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QMainWindow> #define TINS_STATIC namespace Ui { class MainWindow; } class MainWindow : public QMainWindow { Q_OBJECT public: explicit MainWindow(QWidget *parent = 0); ~MainWindow(); private: Ui::MainWindow *ui; }; #endif // MAINWINDOW_H
mainwindow.cpp.....................
#include "mainwindow.h" #include "ui_mainwindow.h" #include<include/tins/tins.h> #include<iostream> 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; } MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { Sniffer("eth0").sniff_loop(callback); ui->setupUi(this); } MainWindow::~MainWindow() { delete ui; }
and when i run this code i get link error as follows:-
mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: __thiscall Tins::IPv4Address::IPv4Address(unsigned int)" (??0IPv4Address@Tins@@QAE@I@Z) referenced in function "public: class Tins::IPv4Address __thiscall Tins::IP::dst_addr(void)const " (?dst_addr@IP@Tins@@QBE?AVIPv4Address@2@XZ) mainwindow.obj:-1: error: LNK2019: unresolved external symbol "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl Tins::operator<<(class std::basic_ostream<char,struct std::char_traits<char> > &,class Tins::IPv4Address const &)" (??6Tins@@YAAAV?$basic_ostream@DU?$char_traits@D@std@@@std@@AAV12@ABVIPv4Address@0@@Z) referenced in function "bool __cdecl callback(class Tins::PDU const &)" (?callback@@YA_NABVPDU@Tins@@@Z) mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: virtual __thiscall Tins::BaseSniffer::~BaseSniffer(void)" (??1BaseSniffer@Tins@@UAE@XZ) referenced in function "public: virtual __thiscall Tins::Sniffer::~Sniffer(void)" (??1Sniffer@Tins@@UAE@XZ) mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: class Tins::PacketWrapper<class Tins::PDU *,class Tins::Timestamp> __thiscall Tins::BaseSniffer::next_packet(void)" (?next_packet@BaseSniffer@Tins@@QAE?AV?$PacketWrapper@PAVPDU@Tins@@VTimestamp@2@@2@XZ) referenced in function "private: void __thiscall Tins::SnifferIterator::advance(void)" (?advance@SnifferIterator@Tins@@AAEXXZ)
etc.......
can someone help me to resolve this out?

I got the solution for this i just cleared the build and rebuilted the project again and it worked for me:-)
Thank u

Hi,
So u did clean , then run qmake , then build and run
Which worked for u?.Thanks,
-
hi,
@Pradeep Kumari cleaned the makefiles in the project build folder and then builded the project in debug mode and then run....
but now i find a problem when it is run in release mode the same error as above is appearing on building and runing the project......... -
Hi,
Delete the build folder and then delete pro.user in the project folder,
then use the same way to build in debug and release mode.Thanks,
