luac.out: incompatible precompiled chunk

I used luac to compile my lua code. The luac version is 5.2.2, and my app native lua is 5.2.2.

My lua code

function hello()
    print("hello test luac ")
end

hello()

The precompiled code:

When I dofile the precompiled code I got error like this:

LuaScriptException: /Users/rik/Desktop/cardGame/client/CardRelease/svn.sh/Assets/StreamingAssets/Lua/luac.out: incompatible precompiled chunk
NLua.Lua.ThrowExceptionFromError (Int32 oldTop)
NLua.Lua.DoFile (System.String fileName)

How can i use precompiled lua code in my app?

Solution

  • The platforms where you've precompiled the Lua script and where you're trying to load it are incompatible in the sense that they have different word sizes or endianness. Lua bytecode is not portable across architectures.
