     基本上都是这样的编译结果。

以前看见过一个文档解释怎样去除编译结果中无用的信息（重复的或者套话），从而得到简化的编译结果。就可以清楚地知道错误所在。

换个不那么远古的编译器

能不能不用这么长的标示符啊？自己把自己搞晕了， 怪谁

VC6对模板支持不好，这个“ identifier was truncated to '255' characters in the debug information”的警告是去不掉的，当它不存在吧

回复 4# hellioncu


    #pragma warning (disable : 4786)
加在#include之前

我怎么记得以前VC6里面，某些警告无法disable掉，包括这个4786

有个大师写过一个工具，可以将这种复杂的错误信息，变为最终的简洁的错误信息。

不过工具的名字我不记得了。因为我认为不能依赖于这种工具，还是靠自己，随着经验的增长，就可以定位问题了。
