靜態庫鏈接失敗

Question

我的操作系統是Windows 7旗艦版，x64。我用cmake，Visual Studio 12.0編譯了這個庫（https://github.com/mfontanini/libtins）。輸出是tins.lib。依賴項：Winpcap，IHPlpapi.lib和WS2_32.lib。 Winpcap似乎獨自工作，我得到了C：\ libtins \ Include中的所有內容以及C：\ libtins中除winpcap之外的所有.lib文件。 main.cpp源代碼來自庫例程。我無法理解有什麼問題，它似乎無法讀取一些功能。以下源代碼的編譯器是Qt Creator。

爲什麼庫無法與Qt Creator鏈接？此外，解決這個錯誤的解決方案是什麼？

Qt的項目文件是這樣的：

QT  += core 
QT  -= gui 

TARGET = libtins_test 
CONFIG += console 
CONFIG -= app_bundle 

TEMPLATE = app 
SOURCES += main.cpp 
INCLUDEPATH += C:/WpdPack/Include 
INCLUDEPATH += C:/libtins/Include 
LIBS += -LC:/WpdPack/Lib/x64 -lwpcap -lpacket 
LIBS += -LC:/libtins -lws2_32 -liphlpapi -ltins 

main.cpp中是這樣的：

#include <tins/tins.h> 
#include <map> 
#include <iostream> 
#include <functional> 
#include <QCoreApplication> 

using namespace Tins; 

class arp_monitor { 
public: 
    void run(Sniffer &sniffer); 
private: 
    bool callback(const PDU &pdu); 

    std::map<IPv4Address, HWAddress<6>> addresses; 
}; 

void arp_monitor::run(Sniffer &sniffer) 
{ 
    sniffer.sniff_loop(
     std::bind(
      &arp_monitor::callback, 
      this, 
      std::placeholders::_1 
     ) 
    ); 
} 

bool arp_monitor::callback(const PDU &pdu) 
{ 
    // Retrieve the ARP layer 
    const ARP &arp = pdu.rfind_pdu<ARP>(); 
    // Is it an ARP reply? 
    if(arp.opcode() == ARP::REPLY) { 
     // Let's check if there's already an entry for this address 
     auto iter = addresses.find(arp.sender_ip_addr()); 
     if(iter == addresses.end()) { 
      // We haven't seen this address. Save it. 
      addresses.insert({ arp.sender_ip_addr(), arp.sender_hw_addr()}); 
      std::cout << "[INFO] " << arp.sender_ip_addr() << " is at " 
         << arp.sender_hw_addr() << std::endl; 
     } 
     else { 
      // We've seen this address. If it's not the same HW address, inform it 
      if(arp.sender_hw_addr() != iter->second) { 
       std::cout << "[WARNING] " << arp.sender_ip_addr() << " is at " 
          << iter->second << " but also at " << arp.sender_hw_addr() 
          << std::endl; 
      } 
     } 
    } 
    return true; 
} 

int main(int argc, char *argv[]) 
{ 
    QCoreApplication a(argc, argv); 
     /* 
     if(argc != 2) { 
      std::cout << "Usage: " << *argv << " <interface>\n"; 
      return 1; 
     }*/ 
    arp_monitor monitor; 
    // Sniffer configuration 
    SnifferConfiguration config; 
    config.set_promisc_mode(true); 
    config.set_filter("arp"); 

    // Sniff on the provided interface in promiscuous mode 
    Sniffer sniffer("eth0", config); 

    // Only capture arp packets 
    monitor.run(sniffer); 
    return a.exec(); 
}

Answer 1

包括使用-L庫-l符號從來沒有爲我使用MSVC編譯器。但我不知道爲什麼。嘗試包括包含擴展名的完整路徑的庫。例如。

LIBS += C:/WpdPack/Lib/x64/wpcap.lib \ 
     C:/WpdPack/Lib/x64/packet.lib \ 
     C:/libtins/ws2_32.lib \ 
     C:/libtins/iphlpapi.lib \ 
     C:/libtins/tins.lib 

甚至包括這些庫的順序在MSVC的情況下也很重要。如果一個圖書館依賴於其他圖書館，則頂級圖書館必須位於最上方。即如果A.lib依賴於B.lib，則必須先添加A，然後再添加B.

Answer 2

這是因爲WpdPack中x64 libs集不完整。您可以嘗試32位或自己構建x64位。
