to_string( const /& n) 是 ambiguos

to_string( const /& n) is ambiguos

本文关键字：ambiguos string const to      更新时间：2023-10-16

我正在开发一个带有二进制cpp-api的软件。

现在我遇到了一个问题，在我安装的raspian和代码块上，我无法使用提供的预编译.so库来处理binacpp头。

所以我读到我需要为我的系统编译它，并试图通过终端运行make，现在发生了这种情况：

现在错误列表更长了，但我试图捕捉终端错误的第一部分和最后一部分。

我试着用以下代码修补它：

#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，这将解决更换每个时的问题

to_string()

带有

patch::to_string()

我试过了，结果完全一样(实际上屏幕截图是编辑后的)

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

就像我说的，我用的是树莓派和rasbian。

以及码块。

提前感谢AD

正如错误消息所说，问题在于调用不明确。不会，除非binacpp_utils.h文件在全局范围中包含自己的to_string模板，和有一个using namespace std语句。这些都是严重的错误，破坏了C++11工具链的构建。

您应该向库的开发人员提出问题。

同时，全局名称空间被破坏了，但您仍然可以在自己的代码中显式引用std::to_string。
