luajit 2.0.0 IOS编译和加载

1：please run at terminal:

注意IOSVER和SIMVER必须和自己实际环境一致

LUAJIT=./LuaJIT-2.0.0
DEVDIR=`xcode-select -print-path`/Platforms
IOSVER=iPhoneOS6.0.sdk
SIMVER=iPhoneSimulator6.0.sdk
IOSDIR=$DEVDIR/iPhoneOS.platform/Developer
SIMDIR=$DEVDIR/iPhoneSimulator.platform/Developer
IOSBIN=$IOSDIR/usr/bin/
SIMBIN=$SIMDIR/usr/bin/

BUILD_DIR=$LUAJIT/build

rm -rf $BUILD_DIR
mkdir -p $BUILD_DIR
rm *.a 1>/dev/null 2>/dev/null

mv $LUAJIT/src/libluajit.a $BUILD_DIR/libluajit32.a

libtool -o $BUILD_DIR/libluajit2.a $BUILD_DIR/*.a 2> /dev/null

2: please add libluajit2.a into ios project.

The libluajit2.a is in LuaJIT2.0.0/build folder.

3: The luajit header files:

mkdir -p $BUILD_DIR/Headers
cp $LUAJIT/src/lua.h $BUILD_DIR/Headers
cp $LUAJIT/src/lauxlib.h $BUILD_DIR/Headers
cp $LUAJIT/src/lualib.h $BUILD_DIR/Headers
cp $LUAJIT/src/luajit.h $BUILD_DIR/Headers
cp $LUAJIT/src/lua.hpp $BUILD_DIR/Headers
cp $LUAJIT/src/luaconf.h $BUILD_DIR/Headers

4:效果

luajit在IOS只对解释器进行了优化，编译器由于权限问题，不能运行。从我测试结果来看，使用luajit后效果还是比较明显的，对比测试可以明显感觉到速度变快了
