如何用庫「lfs」構建lua 5.3？

在我的項目中，我通過在lua的Makefile中添加lfs.c和lfs.h來構建帶有庫「lfs」（https://github.com/keplerproject/luafilesystem）的Lua5.1，它運行良好。如何用庫「lfs」構建lua 5.3？

但升級到lua5.3後，它不能是這樣的：

$ lua test.lua 
lua: test.lua:1: module 'lfs' not found: 
no field package.preload['lfs'] 
no file '/usr/local/share/lua/5.3/lfs.lua' 
no file '/usr/local/share/lua/5.3/lfs/init.lua' 
no file '/usr/local/lib/lua/5.3/lfs.lua' 
no file '/usr/local/lib/lua/5.3/lfs/init.lua' 
no file './lfs.lua' 
no file './lfs/init.lua' 
no file '/usr/local/lib/lua/5.3/lfs.so' 
no file '/usr/local/lib/lua/5.3/loadall.so' 
no file './lfs.so' 
stack traceback: 
    [C]: in function 'require' 
    test.lua:1: in main chunk 
    [C]: in ?

test.lua：

local lfs = require"lfs" 
function attrdir (path) 
    for file in lfs.dir(path) do 
     if file ~= "." and file ~= ".." then 
      local f = path..'/'..file 
      print ("\t "..f) 
      local attr = lfs.attributes (f) 
      assert (type(attr) == "table") 
      if attr.mode == "directory" then 
       attrdir (f) 
      else 
       for name, value in pairs(attr) do 
        print (name, value) 
       end 
      end 
     end 
    end 
end 

attrdir(".")

我已經檢查了最新的「勞動力調查」圖書館是Lua5.3支持的。

我的操作系統是MacOS的10.12，這裏是我使用

您是否在linit.c中添加了lfs？ – lhf

@ lhf非常感謝，這是重點。但是我沒有在我的舊lua 5.1項目的Linit.c中看到這個代碼，這很奇怪...... – BlackOrange

您需要添加lfs到linit.c和重建。

這是我做了什麼和它工作得很好：

linit.c

添加LFS本節：

static const luaL_Reg loadedlibs[] = { 
    {"_G", luaopen_base}, 
    ... 
    {LUA_LFSLIBNAME, luaopen_lfs},

和lualib.h加入

#define LUA_LFSLIBNAME "lfs" 
LUAMOD_API int (luaopen_lfs) (lua_State *L);

然後照常建造。希望這可以幫助。
