编译一个快速修复程序

我正在尝试使用 QuickFix 库通过 FIX 协议连接到代理。我刚刚使用他们提供的文档构建了库，并立即使用他们的示例代码

#include "quickfix/FileStore.h"
#include "quickfix/FileLog.h"
#include "quickfix/SocketAcceptor.h"
#include "quickfix/Session.h"
#include "quickfix/SessionSettings.h"
#include "quickfix/Application.h"

int main( int argc, char** argv )
{
  try
  {
    if(argc < 2) return 1;
    std::string fileName = argv[1];

    FIX::SessionSettings settings(fileName);

    MyApplication application;
    FIX::FileStoreFactory storeFactory(settings);
    FIX::FileLogFactory logFactory(settings);
    FIX::SocketAcceptor acceptor
      (application, storeFactory, settings, logFactory /*optional*/);
    acceptor.start();
    // while( condition == true ) { do something; }
    acceptor.stop();
    return 0;
  }
  catch(FIX::ConfigError& e)
  {
    std::cout << e.what();
    return 1;
  }
}

但是，当我尝试使用以下命令编译它时：

g++ fix.cpp -fexceptions -finline-functions -lquickfix -lpthread -lxml2

我收到一堆错误：

我究竟做错了什么？

您需要提供一个实现MyApplication类并使用适当的 C++11 标志进行编译。

Your MyApplication对象通常需要派生自FIX::Application类是一个纯虚拟类，需要您实现一系列方法，例如onLogon(...) and toApp(...)

如果您只想让代码编译作为第一步，您可以尝试使用FIX::NullApplication类（在quickfix/Application.h 中定义）作为您的启动应用程序对象。
