windows安裝mingw和LuaJIT

1，安裝mingw64

先下載下傳mingw64壓縮包(不建議下載下傳exe安裝包，線上安裝太慢)，位址如下：

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

下載下傳之後解壓到某路徑，然後将其中的bin路徑添加至系統path路徑，例如

E:\Program Files\mingw64\bin

檢查是否安裝成功：

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，編譯安裝luajit

下載下傳luajit：http://luajit.org/download/LuaJIT-2.1.0-beta3.zip

解壓

LuaJIT-2.1.0-beta3.zip

并用cmd進入檔案夾執行編譯指令

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 ===="           

編譯完成之後，将src下面的

luajit.exe

和

lua51.dll

兩個檔案拷貝到建立的

E:/LuaJIT

檔案夾下面，并将src下面的

jit

檔案夾拷貝到

E:/LuaJIT/lua

下面，整體目錄結構如下：

E:\>tree /F luajit
卷 E 的檔案夾 PATH 清單
卷序列号為 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           

最後将

E:/LuaJIT

加入path路徑。

檢驗安裝結果：

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

測試：

建立一個lua腳本

test.lua

print("hello world")           

然後使用luajit進行編譯生成bytecode ：

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

會發現路徑下生成了1.lua的檔案

附：如果使用luajit的時候出現

luajit: unknown luaJIT command or jit.* modules not installed

的錯誤，說明lua子產品放置的路徑有問題，可以通過

luajit -e "require('jit.bcsave')"

指令測試一下luajit的子產品搜尋路徑：

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           

也就是安裝後的jit檔案夾最好放到編譯包

luajit.exe

的同級包的lua檔案夾下
