'255' characters的Warning怎么解决

[happycock]

我只是用了STL啊，这怎么办啊？难道是我使用方法不正规？

你好好看看使用范例～只是使用不规范
有时候会得到 非预期的结果～

ignore it:
put following line at the very beginning of your .cpp files.
#pragma warning( disable : 4786 )

在IDE环境下编译STL程序时，可能会出现如下警告信息
warning C4786: '……' : identifier was truncated to '255' characters in the debug information
这是因为编译器在Debug状态下编译时，把程序中所出现的标识符长度限制在了255个字符范围内。如果超过最大长度，这些标识符就无法在调试阶段查看和计算了。而在STL程序中大量的用到了模板函数和模板类，编译器在实例化这些内容时，展开之后所产生的标识符往往很长（没准会有一千多个字符！）。
对于这样的warning，当然可以置之不理，不过也是有解决办法的。可以在文件开头加入下面这一行：#pragma warning(disable: 4786)。它强制编译器忽略这个警告信息，这种做法虽然有点粗鲁，但是很有效。

[xiaoyunet]

还是使用#progma waring(disable:4786)吧，免得掩盖了其他的警告。也并不粗鲁，明白了原因的警告忽略之，不算粗鲁。

这样的警告是disable不掉的，即使你用了disable:4786，我还是打了SP5 的，
我disable了N次，只有一次好了，但是过了一段时间又出现了
