C++ libtins 构建错误

Question

我正在尝试在 http://libtins.github.io 上的 litbins 构建数据包示例.

我已按照安装说明进行操作并能够 #include <tins/tins.h>正好。现在的问题似乎在于实际引用它的功能。尝试构建此类时:

#include <tins/tins.h>
#include <cassert>
#include <iostream>
#include <string>

using namespace Tins;
int main() {

    NetworkInterface iface = NetworkInterface::default_interface();

    NetworkInterface::Info info = iface.addresses();

    EthernetII eth("77:22:33:11:ad:ad", info.hw_addr);

    eth /= IP("localhost", info.ip_addr);

    eth /= TCP(13, 15);

    eth /= RawPDU("I'm a payload!");

    PacketSender sender;

    sender.send(eth, iface);
}

我收到这个错误:

Netbeans 使用的是 c++11，我已经通过 -DLIBTINS_ENABLE_CXX11=1 启用了 c++11 支持。我跑了ldconfig随着重新启动虚拟机，同样的错误。

我试过将类(class)与 g++ main.cpp -o main -ltins 联系起来得到这些错误 -

感谢帮助。

根据下面 dvnguyen 的回答，链接我的 main.cpp与 g++ app.cpp -o app -ltins -std=c++11解决了上述问题，但现在我留下了以下错误 -

我真的不知道我错过了什么。

从错误日志中的 undefined reference 消息我可以看出您没有将 lib 添加/链接到您的项目。我不知道你的 Netbean 项目设置，但如果你使用 gcc，你可以看到一个例子 here :

g++ app.cpp -o app -ltins -std=c++11
