windows安装mingw和LuaJIT

先下载mingw64压缩包(不建议下载exe安装包，在线安装太慢)，地址如下：

https://nchc.dl.sourceforge.net/project/mingw-w64/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/8.1.0/threads-posix/seh/x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z

下载之后解压到某路径，然后将其中的bin路径添加至系统path路径，例如E:\Program Files\mingw64\bin

检查是否安装成功：

C:\Users\cord>gcc -v Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=E:/Program\ Files/mingw64/bin/../libexec/gcc/x86_64-w64-mingw32/8.1.0/lto-wrapper.exe Target: x86_64-w64-mingw32 ...... Thread model: posix gcc version 8.1.0 (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 2，编译安装luajit

下载luajit：

解压LuaJIT-2.1.0-beta3.zip并用cmd进入文件夹执行编译命令mingw32-make：

E:\>cd LuaJIT-2.1.0-beta3 E:\LuaJIT-2.1.0-beta3>mingw32-make "==== Building LuaJIT 2.1.0-beta3 ====" mingw32-make -C src mingw32-make[1]: Entering directory 'E:/LuaJIT-2.1.0-beta3/src' "HOSTCC host/minilua.o" ....... "CC lj_lib.o" "CC lj_alloc.o" lj_alloc.c:154:14: warning: 'DIRECT_MMAP' defined but not used [-Wunused-function] static void *DIRECT_MMAP(size_t size) ^~~~~~~~~~~ ... "CC lib_init.o" "DYNLINK lua51.dll" "CC luajit.o" "BUILDVM jit/vmdef.lua" "LINK luajit.exe" "OK Successfully built LuaJIT" mingw32-make[1]: Leaving directory 'E:/LuaJIT-2.1.0-beta3/src' "==== Successfully built LuaJIT 2.1.0-beta3 ===="

编译完成之后，将src下面的luajit.exe和lua51.dll两个文件拷贝到新建的E:/LuaJIT文件夹下面，并将src下面的jit文件夹拷贝到E:/LuaJIT/lua下面，整体目录结构如下：

E:\>tree /F luajit 卷 E 的文件夹 PATH 列表 卷序列号为 5EA5-2C1D E:\LUAJIT │ lua51.dll │ luajit.exe │ └─lua └─jit bc.lua bcsave.lua dis_arm.lua dis_arm64.lua dis_arm64be.lua dis_mips.lua dis_mips64.lua dis_mips64el.lua dis_mipsel.lua dis_ppc.lua dis_x64.lua dis_x86.lua dump.lua p.lua v.lua vmdef.lua zone.lua

最后将E:/LuaJIT加入path路径。

检验安装结果：

C:\Users\cord>luajit -v LuaJIT 2.1.0-beta3 -- Copyright (C) 2005-2017 Mike Pall.

测试：

创建一个lua脚本test.lua

print("hello world")

然后使用luajit进行编译生成bytecode ：

E:\Test\lua>luajit -b test.lua 1.lua

会发现路径下生成了1.lua的文件

附：如果使用luajit的时候出现luajit: unknown luaJIT command or jit.* modules not installed的错误，说明lua模块放置的路径有问题，可以通过luajit -e "require('jit.bcsave')"命令测试一下luajit的模块搜索路径：

E:\Test\lua>luajit -e "require('jit.bcsave')" luajit: (command line):1: module 'jit.bcsave' not found: no field package.preload['jit.bcsave'] no file '.\jit\bcsave.lua' no file 'E:\LuaJIT\lua\jit\bcsave.lua' no file 'E:\LuaJIT\lua\jit\bcsave\init.lua' no file '.\jit\bcsave.dll' no file 'E:\LuaJIT\jit\bcsave.dll' no file 'E:\LuaJIT\loadall.dll' no file '.\jit.dll' no file 'E:\LuaJIT\jit.dll' no file 'E:\LuaJIT\loadall.dll' stack traceback: [C]: in function 'require' (command line):1: in main chunk [C]: at 0x00402060

也就是安装后的jit文件夹最好放到编译包luajit.exe的同级包的lua文件夹下
