Question

我正在使用binance cpp api开发一个软件。

现在我遇到的问题是，在我的raspian和安装的代码块上，我无法使用提供的预编译.so库来存储binacpp。

所以我读到我需要为我的系统编译它并尝试运行make via terminal现在发生这种情况：

pi@raspberrypi:~/Desktop/patch/src $ make

现在错误列表更长，但我试图捕获终端错误的第一部分和最后一部分。

我尝试使用以下代码修补它：

#include <string>   
#include <sstream>

namespace patch
{ 
    template < typename T > std::string to_string( const T& n )
    {   
        std::ostringstream stm ;
        stm<<n ;
        return stm.str() ;

    }
}

我在另一个问题中读到，这可以在更换每个

时解决问题

 to_string()

与

patch::to_string()

我尝试了，结果非常相似（实际上截图来自编辑后）

我想要使用的API可以在这里下载：https://github.com/binance-exchange/binacpp

就像我说我正在使用覆盆子pi和rasbian。

和codeblocks。

先谢谢AD

Answer 1

正如错误消息所示，问题是呼叫不明确。除了the binacpp_utils.h file在全局范围内包含自己的to_string模板，和具有using namespace std语句之外，它不可能。这些都是重大错误，已经打破了C ++ 11工具链的构建。

您应该向图书馆的开发者提出问题。

与此同时，全局命名空间已被破坏，但您仍然可以在自己的代码中明确引用std::to_string。

to_string（const /＆amp; n）是ambiguos
