Lua在iPhone上？ [英] Lua on the iPhone?

问题描述

我想在iPhone上使用Lua。在Mac OS X上，在普通（非iOS）Cocoa应用程序中，我使用了以下代码：

I am trying to use Lua on the iPhone. On Mac OS X, in a normal (non-iOS) Cocoa application, I used the following code:

lua_State* l;
l = lua_open();
luaL_openlibs(l);
luaL_loadstring(l, "print(\"Hi from Lua\");");
lua_pcall(l, 0, 0, 0);

我从lua.org/ftp下载了Lua 5.1.4并将其编译为Mac OS X.
在Xcode项目中，我使用添加现有框架添加 liblua.a ，并使用添加现有文件添加包含目录。

I downloaded Lua 5.1.4 from lua.org/ftp and compiled it for Mac OS X. In the Xcode project, I used "Add Existing Framework" to add liblua.a and I used "Add Existing Files" to add the include directory.

这按预期工作，并打印字符串：来自Lua。
当我在iOS项目中尝试相同的事情时，它会给出错误：

This works as expected, and prints the string: "Hi from Lua". When I try the same thing in an iOS project, it gives the errors:

"_luaL_newstate", referenced from:
_main in main.o
more of the same thing...
symbol(s) not found
collect2: ld returned 1 exit status

似乎.a文件未链接到iPhone应用程序。
有人知道如何使这项工作吗？

It seems that the .a file is not linked into the iPhone app. Does anybody know how to make this work?

（顺便说一下，如果它有Lua，我真的不在乎Apple可能不接受我的应用程序在它。）

(By the way, I don't really care that Apple might not accept my app if it has Lua in it.)

推荐答案

你需要为ARM编译Lua .a，而不是Intel。如果Lua库使用autoconf，您可以使用我最喜欢的iphone / autoconf构建器： build_for_iphoneos 。如果它不是autoconf，那么你可以使用该脚本来了解如何攻击它。有时您可以构建一个静态库Xcode项目，将所有文件转储到其中并点击构建。如果构建足够简单，它将为您完成大部分工作。

You'll need to compile the Lua .a for ARM, not Intel. If the Lua library uses autoconf, you can use my favorite iphone/autoconf builder: build_for_iphoneos. If it's not autoconf, then you can use that script to get an idea of how to attack it. Sometimes you can just build a Static Library Xcode project, dump all the files into it and hit build. If the build is simple enough, it'll do most of the work for you.

我知道它对您的使用无关紧要，但基于Lua的工具是通常可以在应用程序商店发货。您无法在运行时下载任意代码并进行解释。

I know it doesn't matter for your use, but Lua-based tools are generally shippable on the app store. You just can't download arbitrary code at run time and interpret it.
