头文件找不到

[刨冰雨]

小弟 win7 64 bit 装了 MinGw(如下) 老是找不到头文件。大虾们帮忙看看

因在MinGW 裡 dos.h中， 沒有定義 date
MinGW Include 中的東西有些會缺少了

[刨冰雨]

[ecsape]

这个不行的
g++ -o Sample8_24 Sample8_24.C -ID:\Program Files (x86)\MinGW\include\


[kazuhikolui] 说的对

仔细看了看 MinGW 的 dos.h 没有发现有关date的东西。

在WIN下有没有更完美的编译环境？

回14楼：
我觉得cygwin还不错，就是太庞大。

MinGw？没听过·······来学习的····

[skyworth98]

你的头文件放在哪儿了？
如果不在当前目录下，或者默认库路径下，你就需要指明头文件路径
貌似是/I

[刨冰雨]

在 D:\Program Files (x86)\MinGW\include\ 目录下是可以找到 dos.h

但程序提示找不到、

环境变量也没问题D:\Program Files (x86)\MinGW\bin;

[G_Spider]

struct date today; 找不到结构体的参照

[hyztcy]

大哥，你自己写的头文件在哪呢？没声明的东西当然编不过去。。

[刨冰雨]

#include <dos.h>
#include <stdio.h>

这两个头文件不是都是C的吗？

struct date today; 这个结构体不是 dos.h 里面的吗？

[owenalen525]

学习了！！

[刨冰雨]

#include <dos.h>
#include <stdio.h>


这两个头文件不是C的吗？

struct date today; 这个有错吗？

[刨冰雨]

#include <dos.h>
#include <stdio.h>


这两个头文件不是C的吗？

struct date today; 这个有错吗？

嘿嘿，TC都没问题,~~~~

[anniue]

看样子是没找到结构体Date的定义了，查找一下date结构体，定义在哪个头文件下，然后再引用进来。

试试：g++ -o Sample8_24 Sample8_24.C -ID:\Program Files (x86)\MinGW\include\
