在cocos2d-x中使用luajit(2)

< -o $@ $(OBJ_DIR)/%.o: ../%.c $(CORE_MAKEFILE_LIST) @mkdir -p $(@D) $(LOG_CC)$(CC) $(CCFLAGS) $(INCLUDES) $(DEFINES) -c $< -o $@
显然对于linux来说，直接使用了lua而非luajit，既然我们要使用luajit，那么有两种选择，一种是将这里Makefile里的lua全部换成luajit，另外一种是将这个Makefile里的lua部分删除，将一个so文件分成两个。因为对luajit不是很熟悉，所以我们采用第二种。新的Makefile文件如下

TARGET = liblua.so

INCLUDES += -I.. -I../luajit/include -I../tolua \
        -I../Classes -I../../../CocosDenshion/include -I../../../extensions -I../../../external/chipmunk/include/chipmunk

SOURCES = ../tolua/tolua_event.c \
          ../tolua/tolua_is.c \
          ../tolua/tolua_map.c \
          ../tolua/tolua_push.c \
          ../tolua/tolua_to.c \
          ../cocos2dx_support/tolua_fix.c \
          ../cocos2dx_support/CCLuaBridge.cpp \
          ../cocos2dx_support/CCLuaEngine.cpp \
          ../cocos2dx_support/CCLuaStack.cpp \
          ../cocos2dx_support/CCLuaValue.cpp \
          ../cocos2dx_support/Cocos2dxLuaLoader.cpp \
          ../cocos2dx_support/LuaCocos2d.cpp \
          ../cocos2dx_support/CCBProxy.cpp \
          ../cocos2dx_support/Lua_extensions_CCB.cpp \
          ../cocos2dx_support/lua_cocos2dx_extensions_manual.cpp

include ../../../cocos2dx/proj.linux/cocos2dx.mk

TARGET := $(LIB_DIR)/$(TARGET)
SHAREDLIBS += -lextension

all: $(TARGET)

$(TARGET): $(OBJECTS) $(CORE_MAKEFILE_LIST)
	@mkdir -p $(@D)
	$(LOG_LINK)$(CXX) $(CXXFLAGS) $(OBJECTS) -shared -o $@ $(SHAREDLIBS) $(STATICLIBS)

$(OBJ_DIR)/%.o: ../%.cpp $(CORE_MAKEFILE_LIST)
	@mkdir -p $(@D)
	$(LOG_CXX)$(CXX) $(CXXFLAGS) $(INCLUDES) $(DEFINES) -c $< -o $@

$(OBJ_DIR)/%.o: ../%.c $(CORE_MAKEFILE_LIST)
	@mkdir -p $(@D)
	$(LOG_CC)$(CC) $(CCFLAGS) $(INCLUDES) $(DEFINES) -c $< -o $@

但是这样一来就没有luajit了，怎么办呢？当然需要编译一个libluajit.so出来了，这个其实很简单，在${COCOS_ROOT}/scripting/lua/luajit/LuaJIT-2.0.1

然后make就会在src下产生一下libluajit.so出来，只需要将这个文件拷贝到${COCOS_ROOT}/lib/linux/release以及${COCOS_ROOT}/lib/linux/debug下即可

到这里，其实已经将luajit准备好了，但是我们需要将工程里的Makefile文件进行一点小的修改，以${COCOS_ROOT}/samples/Lua/HelloLua为例

新的proj.linux/Makefile如下

EXECUTABLE = HelloLua

COCOS_ROOT = ../../../..
INCLUDES =  -I../ -I../Classes -I$(COCOS_ROOT)/CocosDenshion/include \
    -I$(COCOS_ROOT)/scripting/lua/luajit/include \
    -I$(COCOS_ROOT)/scripting/lua/tolua \
    -I$(COCOS_ROOT)/scripting/lua/cocos2dx_support \
    -I$(COCOS_ROOT)/extensions \

SOURCES = main.cpp ../Classes/AppDelegate.cpp 

SHAREDLIBS += -lcocos2d -lcocosdenshion -llua -lluajit -lextension
COCOS_LIBS = $(LIB_DIR)/libcocos2d.so $(LIB_DIR)/libcocosdenshion.so $(LIB_DIR)/liblua.so $(LIB_DIR)/libluajit.so
