静态库链接失败

标签： c++ windows qt qt-creator

我的操作系统是Windows 7 Ultimate，x64。我用cmake，Visual Studio 12.0编译了库（https://github.com/mfontanini/libtins）。输出是tins.lib。依赖关系：Winpcap，IHPlpapi.lib和WS2_32.lib。 Winpcap似乎单独工作，我得到C：\ libtins \ Include的所有包含，以及C：\ libtins中除winpcap之外的所有.lib文件。 main.cpp源代码来自库示例。我无法理解问题是什么，似乎无法读取某些功能。以下源代码的编译器是Qt Creator。

为什么图书馆无法与Qt Creator链接？此外，解决此错误的解决方案是什么？

Qt项目文件是这样的：

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是这样的：

#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();
}

编译输出（Qt Creator）：

使用-L和-l表示法包含库对我来说从未使用过MSVC编译器。我不知道为什么。尝试将库包含在包含扩展名的完整路径中。对于前。

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

在MSVC的情况下，即使包含这些库的顺序也很重要。如果一个库依赖于另一个库，则顶级库必须位于顶部。即如果A.lib依赖于B.lib，则必须首先添加A，然后添加B.

这是因为在WpdPack中设置的x64库不完整。您可以尝试32位或自己构建x64位。
