本文详细介绍了在MINGW环境下，C和C++头文件的路径设置，包括C_INCLUDE_PATH和CPLUS_INCLUDE_PATH的配置，以及库目录和可执行程序目录的设定，旨在解决找不到头文件的报错问题。

报错主要就是头文件目录下找不到相应的头文件！！

C头文件目录%MINGW_PATH%/include下有头文件，里面有strcpy等c函数的声明。
C++头文件目录%MINGW_PATH%/lib/gcc/mingw32/4.4.0/include/c++下有头文件，里面有std::string类的声明。
//家目录
MINGW_PATH=D:/MinGW

//C头文件目录
C_INCLUDE_PATH=%MINGW_PATH%/include;%MINGW_PATH%/lib/gcc/mingw32/3.4.5/include

//C++头文件目录
CPLUS_INCLUDE_PATH=%MINGW_PATH%/include/c++/3.4.5;%MINGW_PATH%/include/c++/3.4.5/mingw32;%MINGW_PATH%/include/c++/3.4.5/backward;%C_INCLUDE_PATH%

//在QTSDK带的MinGW中C++头文件目录均在lib文件夹下
CPLUS_INCLUDE_PATH=%MINGW_PATH%/lib/gcc/mingw32/4.4.0/include/c++;%C_INCLUDE_PATH%

//库目录
LIBRARY_PATH=%MINGW_PATH%/lib;%MINGW_PATH%/lib/gcc/mingw32/3.4.5

//可执行程序目录
PATH=%MINGW_PATH%/bin;%MINGW_PATH%/libexec/gcc/mingw32/3.4.5
