如何设置include目录?

1、项目右键->properties ->general ->paths and symbols，点击add，添加编译器路径

这样可以设置include路径，但是每次建完项目都要改。

2、eclipse中有个project的菜单, 里面有个build project编译下就可以.这个是因为, 必须先编译, 才可以。

问题：splint *.c时报错Cannot find include file stdio.h on search path

解决：

include环境变量里增加stdio.h所在的路径，即：D:\MinGW\include

【1】include头文件路径

除了默认的/usr/include, /usr/local/include等include路径外，还可以通过设置环境变量来添加系统include的路径：

# C

export C_INCLUDE_PATH=XXXX:$C_INCLUDE_PATH

# CPP

export CPLUS_INCLUDE_PATH=XXX:$CPLUS_INCLUDE_PATH
