如何在源代码中声明include目录以外的头文件呢?

nathanial

例如在include/sys/下的头文件.

ysok

#include <sys/***.h>
试试

antijp

还有搜索顺序的问题，譬如
[code:1]
#include <stdio.h>//从Include的路径开始搜索
#include "stdio.h"//从当前路径开始搜索
[/code:1]

cxx

build with -I option

-Idir   Append directory dir to the list of directories searched for include files.
