c++ - Interactive Brokers API C++ 控制台非常基本的东西

Question

IB API C++ 主题有多个答案，但我无法确定所需的答案。我正在努力通过控制台通过 C++ API 连接到 TWS。我不需要界面，只需要在最简单的层面上进行链接。

我正在尝试以下代码:

#include "EWrapper.h"
#include "EClientSocket.h"
#include "textbook_classes_.h" 
//in textbook_classes_.h/.cpp I have EWrapper inheritance with 
//required funcs overriding, 
//those I keep empty (ie:
// void test_EWrapper::tickPrice( TickerId tickerId, TickType field, 
// double price, int canAutoExecute) {}


int main()
{
 IB::test_EWrapper client;
 IB::test_EWrapper* ptr_client = new IB::test_EWrapper(client);

 EClientSocket test_socket(ptr_client);

 test_socket.eConnect( "", 7497, 0, false); //my port is 7497

 delete ptr_client;
 ptr_client = nullptr;

 return 0;
}

我得到的编译错误:

我很感激关于这个非常基本的事情的建议。

附言

我知道有两个非常流行的用户开发的 C++ API 选项:

https://github.com/rudimeier/twsapi

https://github.com/JanBoonen/TwsApiCpp

但它们也不能在我的 Win 机器上运行。

Answer 1

似乎有一个复杂的故事:
1 最好获取最新版本的 API(说真的，从昨天开始)。
2 最好在 VS IDE 中编译它，尽管可能手动更正 IBString.h 以删除 MS 相关声明。
3 不能在2015 VS toolset下编译，请改用2012。
4 你不能让它像从头开始编写几个对象实例化那样简单。最好从原始 IB 文件中删除不需要的内容。
