㈠ C++出現「無法打開預編譯頭文件」錯誤
出錯的原因是包含了預編譯頭文件stdafx.h。但其實這種簡單的命令行程序並不需要。
在創建工程的時候，在向導的第一個對話框里，勾選「空項目」復選框。這樣就不會出現這個錯誤了。
㈡ 用vc建立windows32api程序，編譯時顯示不能打開頭文件windows.h 怎麼弄
自己找到include 文件夾 新建個 txt文件 名字改成 windows.h
然後復制 粘貼進去保存

㈢ 單片機c語言編譯時無法打開自已寫的頭文件
你自己編寫的頭文件嗎？如果是你自己編寫的頭文件，包含進源程序時頭文件應該寫成" "符號進行包含，而不是< >符號，例如你自己寫了一個.h文件叫做def.h，要包含進去就要寫成#include"def.h"而不是#include<def.h>，<>是針對與於標准路徑，看看你是不是這個地方錯了，也可以把你的頭文件添加到標准路徑也可以
㈣ fatal error C1083: 無法打開預編譯頭文件:「Debug\a.pch」: No such file or dir
在 project->settings-> c/c++
Category 選pre compiled headers
選Not using precompiled header
應該就可以了吧
㈤ C語言源文件編譯時找不到頭文件
首先看看這幾個頭文件是否存在？
如果存在記下存放的路徑，檢查頭文件的配置，即查看makefile，看看頭文件尋找路徑是否有剛才的那個路徑。
如果不存在這幾個頭文件的話，那就去找找這幾個頭文件，有可能需要安裝一些庫文件
㈥ C語言，頭文件總是無法在編譯中出錯
可能是你編譯器設置的問題，看看設置的預設目錄是否正確。另外當前目錄包含頭文件用雙引號不用尖括弧即：
#include "stdint.h"
