     基本上都是這樣的編譯結(jié)果。

以前看見過(guò)一個(gè)文檔解釋怎樣去除編譯結(jié)果中無(wú)用的信息（重復(fù)的或者套話），從而得到簡(jiǎn)化的編譯結(jié)果。就可以清楚地知道錯(cuò)誤所在。

換個(gè)不那么遠(yuǎn)古的編譯器

能不能不用這么長(zhǎng)的標(biāo)示符啊？自己把自己搞暈了， 怪誰(shuí)

VC6對(duì)模板支持不好，這個(gè)“ identifier was truncated to '255' characters in the debug information”的警告是去不掉的，當(dāng)它不存在吧

回復(fù) 4# hellioncu

我怎么記得以前VC6里面，某些警告無(wú)法disable掉，包括這個(gè)4786

有個(gè)大師寫過(guò)一個(gè)工具，可以將這種復(fù)雜的錯(cuò)誤信息，變?yōu)樽罱K的簡(jiǎn)潔的錯(cuò)誤信息。

不過(guò)工具的名字我不記得了。因?yàn)槲艺J(rèn)為不能依賴于這種工具，還是靠自己，隨著經(jīng)驗(yàn)的增長(zhǎng)，就可以定位問題了。
