??? 虽说VC是Windows下C++开发的首选工具，但有时候写一些小程序，我还是更倾向于使用一些轻量级的开发工具。比如最近研究Lua嵌入C++，有时候只是写一些很小的程序，这时候Visual Studio就显得太过臃肿了，于是我选择了EditPlus+MinGW的方法。搞了两个晚上，终于搭建好了环境，在这里总结一下，以备将来查看。
??? MinGW的安装比较简单了。我偷懒直接下了个自动安装程序，他会自己去下载最新的包，并解压到正确的位置。为了更方便的使用，还需要配置环境变量，google了一下，还挺多。要是每到一台机器都要这样配置的话，那不是很累。本着计算机能完成的工作绝不自己做的原则，我决定写个js脚本配置环境变量。最开始采用了修改注册表的方法，但是后来发现这种方式修改环境变量是不能立即生效的。又google了一下，改用WScript的shell对象来直接修改环境变量。
?
??? 要配置的环境变量：
??? MINGW_PATH = “MinGW的主目录”
??? C_INCLUDE_PATH = "%MINGW_PATH%//include;%MINGW_PATH%//lib//gcc//mingw32//3.4.5//include ";
??? 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% ";
??? LIBRARY_PATH = "%MINGW_PATH%//lib;%MINGW_PATH%//lib//gcc//mingw32//3.4.5";
??? PATH = "%MINGW_PATH%//bin;%MINGW_PATH%//libexec//gcc//mingw32//3.4.5;";
??? 写成js脚本，把这个脚本放到MinGW的主目录里，双击运行就可以了。?
function GetCurrPath ()
{
??? fso = new ActiveXObject ("Scripting.FileSystemObject" );
??? currFolder = fso . GetFolder ("." );
??? return currFolder . path
}
//取得当前路径
MINGW_PATH = GetCurrPath ();
C_INCLUDE_PATH = "%MINGW_PATH%//include;%MINGW_PATH%//lib//gcc//mingw32//3.4.5//include " ;
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% " ;
LIBRARY_PATH = "%MINGW_PATH%//lib;%MINGW_PATH%//lib//gcc//mingw32//3.4.5" ;
PATH = "%MINGW_PATH%//bin;%MINGW_PATH%//libexec//gcc//mingw32//3.4.5;" ;
var WshShell = WScript . CreateObject ("WScript.Shell" );
var WshSysEnv = ? WshShell . Environment ("SYSTEM" );
WshSysEnv ("MINGW_PATH" ) = MINGW_PATH ;
WshSysEnv ("C_INCLUDE_PATH" ) = C_INCLUDE_PATH ;
WshSysEnv ("CPLUS_INCLUDE_PATH" ) = CPLUS_INCLUDE_PATH ;
WshSysEnv ("LIBRARY_PATH" ) = LIBRARY_PATH ;
PATH = PATH + WshSysEnv ("PATH" );
WshSysEnv ("PATH" ) = PATH ;
WScript . Echo ("MinGW环境变量设置完成！" );
?
??? 接下来是Lua环境，下载Lua的bin和lib以后，做成下面的目录结构：
Lua
│
├─bin
│????? bin2c.exe
│????? lua.exe
│????? lua5.1.dll
│????? lua51.dll
│????? luac.exe
│????? wlua.exe
│
├─include
│????? lauxlib.h
│????? lua.h
│????? lua.hpp
│????? luaconf.h
│????? lualib.h
│
└─lib
??????? lua5.1.lib
??????? lua51.lib
?
??? 然后仍然是js脚本配置环境变量：
function GetCurrPath ()
{
??? fso = new ActiveXObject ("Scripting.FileSystemObject" );
??? currFolder = fso . GetFolder ("." );
??? return currFolder . path
}
//取得当前路径
LUA_HOME = GetCurrPath ();
LUA_BIN = "%LUA_HOME%//bin;" ;
LUA_INCLUDE = "%LUA_HOME%//include;" ;
LUA_LIB = "%LUA_HOME%//lib;" ;
var WshShell = WScript . CreateObject ("WScript.Shell" );
var WshSysEnv = ? WshShell . Environment ("SYSTEM" );
WshSysEnv ("LUA_HOME" ) = LUA_HOME ;
//bin加入path
WshSysEnv ("PATH" ) = LUA_BIN + WshSysEnv ("PATH" );
//include加入MinGW
WshSysEnv ("C_INCLUDE_PATH" ) = LUA_INCLUDE + WshSysEnv ("C_INCLUDE_PATH" );
//lib加入MinGW
WshSysEnv ("LIBRARY_PATH" ) = LUA_LIB + WshSysEnv ("LIBRARY_PATH" );
WScript . Echo ("LUA环境变量设置完成!" );
??? 有时候设置好了却不生效，重启一下就好了。先写个Hello World测试一下。
#include <lua.hpp>
#include <iostream>
using namespace std ;
int main ()
{
??? lua_State * L = lua_open ();
??? lua_cpcall (L , luaopen_base , 0 );
??? if (luaL_loadfile (L , "test.lua" ) || lua_pcall (L , 0 , 0 ))
??????? cout << lua_tostring (L , - 1 )<< endl ;
??? lua_close (L );
??? system ("pause" );
??? return 0 ;
}
??? test.lua:
print (" Hello World!" )
??? makefile:
all : main.exe
#all:rebuild
??? main.exe
main.exe : main.o
??? g++ -o $@ $^ -llua5.1
main.o : main.cpp
??? g++ -c main.cpp
clear :
??? -del *.exe *.o
rebuild : clear main.exe
??? 直接make，编译、连接、运行一次搞定。
g++ -c main.cpp g++ -o main.exe main.o -llua5.1 main.exe Hello World! 请按任意键继续. . .
