C4503警告？我如何解决/摆脱他们？ [英] C4503 warnings? How do i solve/get rid of them?

问题描述

这是我第一次尝试C ++ STL。我试图使用map构建一个多维关联数组。例如：

It's my first time trying out C++ STL. I'm trying to build a multidimensional associative array using map. For example:

typedef struct DA {
    string  read_mode;
    string  data_type;
    void    *pValue;
    void    *pVarMemLoc;
}DA;

int main()
{
    map<string, map<string, map<string, map<string, map<string, DA*>>>>> DATA;

    DATA["lvl1"]["stg1"]["flr1"]["dep1"]["rom1"] = new DA;
    DATA["lvl1"]["stg1"]["flr1"]["dep1"]["rom2"] = new DA;
    DATA["lvl1"]["stg1"]["flr1"]["dep1"]["rom3"] = new DA;

    IEC["lvl1"]["stg1"]["flr1"]["dep1"]["rom1"]->read_mode = "file";
    IEC["lvl1"]["stg1"]["flr1"]["dep1"]["rom2"]->read_mode = "poll";
    IEC["lvl1"]["stg1"]["flr1"]["dep1"]["rom3"]->read_mode = "report";

    return 0;
}

在VS2005中编译上面的代码时，我得到了170个C4503警告。
所有警告都是关于装饰名长度超过，名称被截断。
程序似乎运行良好，虽然。

When compiling the code above in VS2005, I got 170 of C4503 warnings. All of the warnings are about "decorated name length exceeded, name was truncated". The program seems to run fine though.

任何人都关心有一些时间来解释我是什么导致这些警告，我如何解决em？提前感谢：）

Anyone care to spare some time to explain to me what caused these warnings and how do i solve em? thanks in advance :)

推荐答案

如果你打算保留这个怪物的数据结构，可以对其他警告进行禁用：

If you intend to keep this monster of a data structure, there is little you can do about the warning other than disable it:

#pragma warning(disable:4503)
