我正在尝试使用quickfix库使用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;
}
}
然而，当我尝试用：
编译它时g++ fix.cpp -fexceptions -finline-functions -lquickfix -lpthread -lxml2
我收到了一堆错误：

我做错了什么？
答案 0 :(得分：0)
您需要提供MyApplication类的实现，并使用适当的C ++ 11标志进行编译。
您的MyApplication对象通常需要从FIX::Application类派生，该类是纯虚拟类，并且需要您实现一系列方法，例如onLogon(...)和{{1} }
如果您只想将代码编译为第一步，可以尝试使用toApp(...)类（在quickfix / Application.h中定义）作为起始应用程序对象。
答案 1 :(得分：0)
必须使用此预处理程序指令HAVE_STD_UNIQUE_PTR
您的应用程序必须为MyApplication类提供一个实现，并且该实现必须继承自FIX :: Application
