出现错误Cannot find include file std

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
